[CU2] funny noise from the engine when slow accelerate

[eur001]

I was in Perth last week and went with a friend to a dealer on the Leach Highway. My friend was interested in the CU2. We chatted with a youngish salesperson who seemed to know his stuff. Then I asked him directly about whether the pinging problem had been solved. He paused and then acknowledged that there was a pinging problem. But then he went on to say that Honda had solved it as they had discovered that owners had actually been fuelling up with 91 RON ULP instead of 95 RON PULP.

Well, I thought to myself: 1. He confirmed the existence of the pinging problem; and 2. He still wanted to sell my friend the CU2 no matter what.

So your friend end up buying the car??

Pinging.

I also have it, 2009 Accord Euro Automatic. Happens when under load at about 1800- 2500 rpm. At 1000km, service guy heard it immediately, said that should wait for 10,000km service because loosening up of engine may correct it. Car has only ever had 98 unleaded, so I doubt it is related to that.

Car is eerily quiet anyway, much quieter than the new Mazda6 I test drove, so it is most annoying on the freeway in cruise because engine sits at 2000 rpm and pings the whole way!

Have written to Honda.

That's a new one. Could you please tell me which dealer told you this/
