NEW 2009 Euro Luxury Auto Pinging

I've solved my pinging issue with my car, and no I didn't sell it to get something else.

I've clocked over 700km after a small change and since then the car hasn't ping once. I've filled up 1/2 tank of fuel from different servos about 4 times now just to discount that its not a servo related issue.

After a spirited drive up and down the Nasho this afternoon and being stuck behind slow moving traffic I can successfully say that I haven't heard the car ping.

I drove in normal and sports mode and I use the air con all the time. Wow its good not to have to worry about the pinging from the engine anymore.

Hell yeah, I took it to Nasho on the weekend, and clocked 16 litres/100km in spirited driving hehehe. I'm going to retract my comment on what a sh!t car the CU2 is. After the pinging has been solved, I played around with the tyre pressures - now running 38psi all round and this really transform the car. No more spongy ride. Even at 38PSI the stock suspension handles the bumps without bottoming out. Handles off camber corners really well at spirited driving.

You need to rev the **** off the engine, ie keep it about 5000-7000rpm and the CU2 is actually a very nimble drive. I just wish there is a way to turn off the electric power steering at above 70km/h. The steering is still too light and numb for my liking.

So how did you fix the issue? or am i blind.. :D

I have an MY13 CU2 6MT which is pinging. For reference I've always filled up with 98 (BP/Shell) from metro service stations that get plenty of traffic.

The car seemed ok for the first 1000km, it became noticeable around the time the 1500km service was done. Nothing was noted during the inspection.

A week after the 1500km service was done I took it in to have it checked, the service manager had a quick listen and told me to mention it when I dropped it in for the 6 month/10,000km service.

During the next two months it became even worse, especially when it was cold. At around 3000-3500rpm it literally sounded like a diesel, so I pretty much avoided driving the car unless absolutely necessary.

Two weeks ago, with just on 2000km on the clock I took it back again, booked in to be checked over on the 5/10. They noted a misfire/ping starting at around 3100rpm. They replaced the plugs, checked the injectors (fine), tested the fuel (fine) and the operation of the knock sensor. They added some injector cleaner and gave it back to me to see how it went. It seemed ok driving home from the dealership, but the next morning it was back to how it was before.

On the 10/10 I took it back in, they had it 3 days so they could test it while hot & cold, apparently were in contact with Honda's technicians most of the time trying different things to fix it. I picked it up on the 12th, was told to run out the remaining fuel (2/3 tank) and then fill with BP. The service manager pretty much admitted that fuel wasn't going to be the cause, since it was fine sometimes. During the time it was in they damaged the centre console and left something loose under the dash, they've said they'll fix it though.

The next day, it was just as bad as it was before it went in. At 3000rpm it sounds like a tractor. They promise no damage is being done, but I'm not convinced.

At this stage I'll play their game, run the fuel out and try a different brand, but I'm fairly certain it'll make no difference.

Does anyone have any advice on how to proceed?

38psi is like 2.6 bars? That's a bit higher than the 2.2 recommended for usual driving. Gotta try this though :) The CU2 just begs to be driven hard.

As for pinging, would it be a high pitched ringing sound or a low pitched clatter? CU2's here in China are tuned only for RON93 so I'm wondering if pinging is happening on the crap fuel.

Im so suprised this is still and issue with the Euro! I had the knock sensor and software upgrade completed under warranty in October 2009 with the 12month/20k service. No pinging evident there after. My MY09 6MT Standard has now covered 50thou kms and I run either 95 or 98 octane fuels without the post combustion noise.
Also, like BigBen's post above I run 38psi as recommended in the Falken tyres that Ive fitted now as replcements to the original Bridgestones.

I had the same problem with my non euro Accord (new shape) for almost 3 years. It has been back to the dealer countless times with no luck until my bad battery blew my ECU which was replaced under warranty and it has been fine since.

2.2 bar feels like a boat floating in rough waters.

No damge is done...i would get that in writing from them.

To follow up on this:

I ran out the remaining fuel as instructed and filled it with BP ultimate, but still had the same issues.

I dropped it back in on the 29/10, this time they had it for four days, during which they did replace the scratched console trim. When I picked it up it still had the same problems, I took it for a drive with the foreman who noted exactly what was happening and said they'd replace the knock sensor and make some further adjustments.

15/11 it went back in. Today it had been eleven days and not a single call, so I called to ask what was going on, the service manager told me the knock sensor hadn't come in, but it should be there in a few days.

This evening I called Honda Australia and lodged a complaint as I felt it's past the point of being a reasonable amount of time since the dealer was made aware of the problem and at this stage they still haven't fixed it.

Picked up the car today. It's still pinging.

The service department have said they've done everything they can, so now an inspector from Honda Australia will need to look at it. Looks like it'll either need to be a new engine, a new car or a refund.
