NEW 2009 Euro Luxury Auto Pinging

[aaronng]

I am still not convinced some of the problem is not timing chain related, which is a known problem area on K series engines.

Never heard of the timing chain problem on the K-series. Only the weak OEM timing chain tensioner. What is the timing chain problem?

it has never been a big problem, but it is a known problem where on occasions you get some timing slight timing chain slap as the variable intake cam drive gear goes though its normal few degrees of movement. Often it is associated with a weak timing chain tensioner. The normal fix in my time was replacement of chain, guides & tensioner.

Hi guys, thought I would post an update on here for others' information.

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.

I have only had the software update done, still waiting for the knock sensor & after a little over 2500km since the update I regard the pinging issue as solved. So basically i am not worried about the knock sensor, but will take it if & when the time arrives.

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.
