Had my 12 month service yesterday and the dealer told me they had logged the problem with Honda and would be in touch when it is my turn. I reported the ping 6 months ago but apparently it doesn't pay to be patient!

Anyway they did some testing and the service report says,

"Checked and Confirmed post combustion sound at about 1,500 to 3,000rpm light throttle, carried out tests as per bulletin (fuel colour yellow premium) and logged all information with Honda technical will call when counter measure part and software is made available".

I have also noticed a couple of times that under certain conditions if you plant your foot the engine bogs down for a second or two before bursting back to life. I think I read somewhere that this problem is also related to the knock sensor. Any one know if this is correct?

That's the electronic throttle. Happens to the previous CL9 as well.

Do you feel any difference? I wonder if you don't have the problem, will they still change it?

The knock sensor has been ordered & I will be notified when it arrives. My dealer has told me that customers who complain about pinging will all receive software update & knock sensor, for customers who dont complain, the software update alone will be carried out as they come in for routine servicing. As for any differences, I can honestly say nothing that is noticeable, driveability & economy are exactly the same. The only possible exception & I can't say this with total honesty as i rarely give the car its head, but on the 1 occasion I have since the update it appears the rev limiter cuts in earlier. On previous occasions i have had no trouble taking it to 7500rpm in sport mode before i use the paddle shift, ( i had read that the limiter cuts in at 7900), but last lime I tried the limiter cut in about 7400RPM...... no great drama for me, i will just lower my shift point a little.

Good to hear theyve finally come up with a solution to the pinging.
I have a manual CU2 (now 11000kms old).
I registered my pinging issue with Honda Australia on advice from my Honda dealer of purchase and I havent been notified as yet. Will chase it up.

Which dealer did you go?? I went to Burswood. They did my car few months ago and since then i can hardly hear the ping.

I had a CU2 which I purchased in July 2008, which had the pinging issue. I was on the list of those awaiting the fix. Whilst it was annoying, I absolutely loved the CU2 in every other respect. Anyway, because of the government 50% investment allowance on new vehicles, I got the opportunity to trade up to a new car at very little changeover cost. I looked at all the pros and cons and decided to change a CU2 for a CU2. My old one had 27,000km on it at changeover (I do a lot of kms).

At delivery I straight away noticed the new car had the same pinging issue. I had raised this issue in negotiations and so handed it straight back to the dealer and said I either want the ping fixed or a new car that doesn't have the noise.

Long story short, I had the fix applied to the new car (software plus knock sensor) and it has made a big difference. To be honest I think there has been a *hint* of a ping a couple of times, but if I wasn't listening for it I would never have noticed it. I have exhaustively tested it under conditions which previously would have had it pinging its bum off and have been unable to fault it. This has been a really drawn out and annoying issue with my previous CU2, but I'm happy to report that in my new car it is now sorted out and I am enjoying the car immensely.

Hey guys,

I just got a phone call from my dealer, my knock sensor is here and I have my CU2 booked for next week. Hope this will solve the problem coz my car is pinging on 1500, 2000, 3000, 4000.... rpm :eek:

I will post some information when the fix is applied, wish me luck ;)

Gday to All

Im having a 10,000 km's service this Friday.

Also i was advised the new sensor will be applied to my car and any new software.

Anyhow the previous software did not fully resolve the post cumbustion noise.:eek:
The car will then be driven to the Gold Coast so it will allow me to monitor if the annoying ping is still there.
I will also provide you some fuel consumption figures.
All the best to you all and remember to keep pestering Honda.

Reported the pinging problem to my dealer who will register the car to receive the software update and new knock sensor.

I have actually filled up my CU2 with Caltex Vortex 95 over the previous week as a) it was really cheap petrol that day b) test see how it compares to Ultimate 98

I need to do more testing but it seems with the Vortex 95 the metallic ball rattling sound seems to be louder with full tank and progressively diminishes as the fuel reaches 3/4 empty (I still had a bit of Ultimate 98 left from previous fill)

Gonna go back fill up with Ultimate 98 today and see what happens.

Best of luck with the updates Vid, Hope it is as successful as mine was. get it up into the hinterland on a few hills, that will test it out. 6.47L/100 is the figure to beat, lets see if yo can manage it?

Okay, an update - drove until the tank's nearly empty and re-filled with Ultimate 98, definitely less pinging noise than the Vortex 95 and the engine feels like it's running a lot smoother as well.

Can still hear pinging noise but my hearing's very sensitive and I don't think it'll bother anyone else.

Hello People

I have been informed by a dealer that Euro MY10's don't have the so called Pinging issue , it was only a certain Vin range. You mob think that this dude is pulling my leg?

Went to dealer this morning, and saw a lady came and said to the dealer that she came for the "post combustion recall". I asked her what and how she got the info, and she said the dealer just rang her to bring the car in for this (eventhough she didnt know anything about the pinging problem).

I've then asked the service manager, he said that they are recalling the CU2 based on VIN. He checked my VIN number and told me to wait until its my turn soon.

Note that this lady never reported any pinging issue to the dealer, nor to Honda Oz, but she still get the "fix".

OK, had my car fixed yesterday.

They changed the knock sensor, ECU and transmission SW, this is what I've been told.
Was driving the car since yesterday and I'm happy with the results so far.
NO PINGING NOISE at the moment, I really hope this will remain as it is.

Service centre told me the car will learn its settings for next few tanks of fuel and it should work without any issues. I did noticed some change in the shifting, like the car became more smooth to drive. Didnt notice any improvement in power, but its still early to discuss.

had to sell the evo due to p plate restrictions and got busted so had to buy a euro and thought might as well buy a brand new 1 it seems appealing

all i really want is for the noise to disspear i couldnt care less of whats casuing it or why it is making the noise but telling me bollocks like fuel quality i just cant accept that as an cause of the pinging thats how i feel anyways from my common sense

the person i have contacted her name is

very helpful lady relpied emails on a fast pace and promptly, even thought i got abit peed sometimes but cant blame her she dosnt own honda. i guess we all gotta understand these people are just told what the problems are and are rlying to us seeing they are a customer service spepcialist. When we speak to them please keep our cool and know that they are only our first point of contact but i guess gotta be pushy to get results.

and just on a note my EURO has never even touched 95Octane unless on Delivery thats what it had but ever since first tank went empty the car has been running on MOBILE 8000 and Shell V-Power
When was told the FUEL quality i even Tried the V-Power Racing 100Ocatne which i put in the evo sometimes when i go on cruises
that did not stop the pining either that basically kept me on thinking its the gear a few of my mates said it's the gear as well when i told them to test drive but o welps i aint no mechanic lol. just have to go by what im told by the techs i guess

I've just emailed Irene as well, hoping she'll come back to me with the positive confirmation on the availability of the fix and I'll keep everyone here updated.

Hey mate,

Did you just go to the centre and ask them to apply the fix? 'cos I'm going to do the service soon, though I've asked them to keep me updated on this issue, not sure if they would apply the fix during the service without being asked. What's the process? Thanks!

Well, so far and as I know the process is as follows.
1. You go to ur dealer/service, they check the car, take fuel samples bla bla bla
2. Ur dealer will send the report to HA
3. HA will request knock sensor for your car
4. When the knock sensor arrives in AUS, you will be contacted by ur dealer and ur car will be booked for repair.

Above process applied for me, I think it will be the same for everybody.
At this stage have the car 3 days after fix was applied, no pinging is heard, however, less power I notice and increase in fuel consumption. But for this statement I believe is too early as I was adviced by service manager that the car will be in learning process for next few weeks/tanks :)

Cheers

^^^ Like I sed, the dealer told me to wait until the recall is out (not for long now, according to him). So, when I report this problem, they didnt (or at least, I thought they didnt) do testing, etc as reported. Cause, according to the service manager, HA has inform them that there will be recall to fix this issue.

Post Combustion Noise

Guys

Last Friday 11th Sep

I had a new computer, knock sensor, and some manifold adjustment performed
as a countermeasure for the post combustion noise.
I was advised to fill car with 98 RON for 3 fills.

Anyhow i tested it myself and im happy to report that the noise is 98% corrected, basically if you had the radio on you would not hear it all.
It would help if you are slightly deaf :zip:, as my hearing is very acute especially when it comes to the CU2.
The latest Honda bulletin will indicate to dealers to start calling customers
to bring problem Euro's back for the countermeasure.
I must say Capital Honda were very professional and treated me like Gold :cool: ....:thumbsup:

I wish you all well with your dealers

LOL, I believe u are a gold for them, bearing in mind u left at least 40k with them ;)
So when you are saying at least 98%, can you still hear something? coz I had mine fixed too on friday and I cant hear any pinging and Im not deaf especially when it comes to my CU2 too :P
About 98 or 95, I was adviced by my dealer to keep using the same fuel I will be using in future as the car will be learning for next few refills.

Anyway, noticing the car running more smooth on a start and increase in fuel consumption in general I am happy that I dont have the ping anymore

I would definetely purchase the car, it is the best car Ive owned so far and even if there was no fix for the pinging I still purchase the car. Thats my own opinion. Many ppl here will agree with my words and I know even ppl that are not bothered to fix the pinging too. Car is awesome to drive and the fact there is resolution on post combustion sound makes it more cool.

Thanks mate! I just got a call from my dealer and was asked to bring my car in and they will do the fix and service on the same day, 'cos the fix will take a whole day according to the call. Apparently, they still keep my report about the issue, though they hadn't contacted me ever since I reported it officially in Jan last year.

I'm getting excited to see the annoyance to be fixed finallly! But I'd better chill I reckon.....

Will keep you guys updated after the fix on next Thursday. Cheers.

A bit of an update: I had the fix applied about 2 weeks ago. It's much improved but there is still a very slight noise there under gentle acceleration. Hard acceleration is fine (which is interesting as this used to have it pinging wildly). I'm on my second tank of 98 RON fuel since the fix. Probably wouldn't notice the noise at all if I wasn't listening for it and can't hear it with the radio on.

Got a call from my dealer today to tell me that my car had arrived so I dropped in to take it for a drive as I'm not officially taking delivery until Oct 12th.
Happy to report that there was no sign of any noise. Mine is a MY2010 so it's probably had the fix applied.
Also happy to report that the rear parcel shelf is now black.

OK there is no drop in performance at all, the car feels very smooth through the gears.
Im actually no longer concerned about the noise
as it is no longer a problem...

I have covered 10K and the motor can only get better.
Im not sure if any Auto owners have issues with sluggish performance
all i can report is that the manual does it's job extremely well, when it hits 4000 rpm:cool:
my trip to the gold coast next week will give me ample time to monitor consumption and speed in overtaking.
I will post some stuff to you guys after that....

He said in My10 model the pinging issue is fixed from factory.

I hope what he said is true....

I have been told the same from the dealer, the MY10 don't have the pinging issue.

However, I do hear some sound from the engine when accelerating, usually above 2000 rpm, not sure whether is the post combustion sound. Will be in for 1st service tomorrow, will let them to check that.

If its like a rattle noise, 99% is the pinging issue. Moreover 08, 09 and '10 models coming out of the factory with the issue. Dont worry, just ask the service to check it and they will fix it in future :)

FYI - havent been on this site for a couple months - Called Honda on monday complaining again about the pinging as they initially said it would be all sortted by July / August. Got a call on Wednesday saying the 'kit' was now in store for my car (i was on a list for the fix since march this year)... took the car in for 1/2 day on Thurs... now runs extremely well, ultra quite and smooth. Better than when picked up new!! Not a sound from the engine and no sign of pinging whatsoever! They tell me they changed the knock sensor and reprogrammed the computer. They also tested my fuel to double check i was running on premium!! (cheeky buggers)

Most importantly, there is no difference in power and/or fuel consumption!.... If your car is pinging, CALL HONDA and demand the fix - they are now capable of making your car run HEAPS better!!! Keep on their back - if you dont call them, they wont call you! Cheers...

I'd like to see them do that: More like bluffers. The test for the Research Octane Number (RON) requires a special single cylinder test engine that is very expensive and tends to be owned by car manufacturers and engineering departments of some Universities. I doubt a humble dealership would own one or have ready access to one.

It reminded my of a local dealership who used to go racing at the local raceway just so they could spy on which of their customers were racing their cars and then telling them that their warranty was void. Legally all rubbish as they would need to establish that any damage was actually caused by the customer's actions.

Have my car in for 1st service today, confirm that my MY10 model have the pinging problem. Booked in to have the "kit" installed aka FIX next Thursday, because they have to order the parts from Honda.

Don't know about Honda, but my dealer is taking this problem very seriously and they are really doing a good job. So, i'm happy :)

Pick a steep hill, and accelerate hard uphill and see what happens.... My Euro still pings with 98 RON and fuel treatment the dealer put in.

Has anyone tested this?

Off topic: The dealer also did an engine flush at the 6 month service and didn't replace the oil filter (doesn't seem normal, does it?). Will be calling him up on Monday to find out WT* they did???

I tested mine in pretty much all possible conditions, no ping at all.
P.S. I am driving the car with Caltex Premium 95 all the time.

Alright, in Perth here, Prestige Honda's got the knock sensor and software fix ready to go - gonna do the fix at the same time with my CU2 10,000km's service next week on Friday!

Wish me luck!

I dare say when pushed hard, most Euros are likely to ping....

Here is what Honda Australia had to say about this issue:

Honda Dealer - "I’ve had a call first thing this morning from my Honda Technical contact in Melbourne instructing me to pass on to you that the vehicle will require an extended learning phase of 3 full tanks of high quality fuel 95 & higher and then we need to reassess the situation."

So, there you have it....A pretty lame response to a very serious problem.

note that all honda dealer that have install the fix to CU2 owner said the same thing consistently, so it might not be a lame response afterall...

So what's this learning phase for then? If we have been filling up the car with 95 and / or 98 RON then is it still necessary?

I think overall that the Euro CU2 can't take fuel lower than 98 RON despite being stated as able to do so.

I've been running on Ultimate 98 and this has minimised any pinging so far to the point that it's not even audible.

I am now on my third tank of BP Ultimate 98 since the fix. Still a very slight ping there under moderate acceleration, but it seems fine under heavy acceleration (even under load up a steep hill). I'm not sure about this "learning" phase - if anything the noise is slightly worse on tank 3 than tank 1, but it's still very mild.

It is still necessary, if they change the mapping it takes time for the system to learn. Same if you keep changing fuels.

I stick to Caltex 95 RON and the car seems happy on it, on the odd occasion I have used 98 I noticed no difference at all.

Thanks for the info Sludge, I'll post here once I've got the car fixed next week and serviced and let's see how it goes from there!

Over a distance of 18,000km I have used Caltex 95 exclusively apart from 2 tanks of 98 that I tried several months ago (Which made no discernible difference). I have only had the software update so far - knock sensor has not been replaced yet and my pinging problem has been completely eliminated.

Thats a worry...My dumbarse service advisor told me its not pinging but post combustion detonation and hear this..The cu2 is not ivtec and does not have vtec on the exhaust side for fuel economy reasons. He also says to get the increase in power over the cl9, honda had to play with ignition timing and air/fuels.

Buddah, excuse the noob question but just wondering: most of those that still have some mild pinging have had both the software update and knock sensor replacement. Do you think there is any significance that you only had the SW update and your pinging is completely fixed? Could the software update on its own be more effective than software + knock sensor replacement?

I can't answer that with any certainty, when my software update was done I was told a knock sensor had been ordered & I would be advised when they received it. I haven't followed up on it yet as i no longer have the problem (I have done over 3,000km since the software update). It is therefore no longer an issue for me personally, but in saying that i think i did hear it very faintly on 1 occasion only for 1 or 2 seconds.

What disappoints me more is the reported response from some dealers over this problem. All I can suggest to those who get such a response would be to find another dealer.

It's been a while since I checked in.

I've had the fix done about 300ks ago and it's been perfect since. No pinging at all and feels more powerful.

I'm pleased with the outcome.

Had my upgrade done at the belated 30k service. No pinging evident at all & also feels slightly more responsive than before.

All good

Excuse the n00b question, buddah51au - but this "learning" will it be lost when say the battery is cut?
24-09-2009, 01:02 PM

To my knowledge once the Battery is cut the learning process needs to re-start

True but the base settings stay the same; i.e. there are default maps.

It's interesting how many people are finding an increased responsiveness after this software update. I have a CL9 and it always feels more responsive after an ECU reset. This increased responsiveness you feel would probably not be due to the actual software update. It will be a short lived thrill.

^^ My CL9 always goes noticeably better after a service. It's all downhill after that because I tend to drive for economy so it learns that.

I live in NZ and I had my knock sensor and ECU update done today. It was quite bad before the update and I'm happy to report it seems pretty good now. The car did seem a bit more responsive and the a/t seemed a bit smoother also. I'm looking forward to spending some more time in the car to see what the lasting impression is.

Cheers,

David.

Yeah! As promised, I got the knock sensor replaced and software updated yesterday. So far, I feel greatly relieved enjoying the beautiful and smooth accelerating sound as it should have been for the whole last year.

I do feel it's more smoother when I push it to the extent around which I used to hear the annoying rattling. After almost a year suffering from hearing it, I know it so well that even though it wasn't 'reproducable', when it started making to pesky noise, I was just so confident to know how much I pushed the pedal and in what specific situation I would hear it. Sadly and ironically, I'm just so used to it and even my mind still tried to make the short-gone noise instead......I reckon the trauma would stay a bit longer than I thought.

I'll definitely keep monitoring it and update here. Hope we all have it fixed in peace.

Cheers!

It is my understanding that the base settings on the ECU are set for maximum performance meaning constant full throttle driving. As this is not constantly repeatable with road driving, nor would many of us drive our cars in such a manner for that matter, once the ECU is reset which can be done by disconnecting the battery it will take a few weeks for the ECU to learn our individual driving habits.

As we all drive differently, whether it be spirited driving or driving with economy in mind I always suggest to people to try and use the complete rev range at least once a week providing the engine is hot & of course it is safe to do so in the area you drive.

I have had a number of discussions with Fair trading in NSW, it seems that whilst everyone here is happy to have a whinge and wait, no one is willing to step up to the plate.

Fair Trading require anyone that has this problem to report it, so that they can exert some pressure.

If you are serious about getting your car fixed, take the right steps!

I've been doing some more driving and I have some further feedback.

My car suffered from the 2.5k light throttle issue and also noticeable pinging when I nailed the throttle at 4-5k. Less obvious was a general hard/loud note to the engine when reved out. I've previously self tuned a DC5R with K-Pro and based upon what I was hearing from my Euro I would put the noise down to a slight lean mixure with mild over advanced spark.

So far the 2.5k light throttle issue seems gone as is the 4-5k issue. I was really hoping that the changes were going to help the hard/loud engine note and I'm happy to report it does seem to be making big strides in that area. I think it's improving each time I drive it and the engine note seems much sportier and tuneful.
