Hi All,

I'm new to the forum but have been lurking on here for 3 weeks since buying a 2006 2.2 ES.

Appologies if this has been asked before, but I couldn't find anything like it.

My car needed a clutch/DMF when I bought it, but I knew and got it cheap. I drove the car for a week, got used to it and then booked it into a local clutch specialist who seamed to know what he was talking about and said he had done lots of these before. He didn't even need to lookup prices and quoted them straight away so sounded fairly experienced with these cars.

When I got the car back the engine was making a noise like pinking whenever I was on the throttle. Before the clutch was done the engine was very quiet, just had a bit of turbo whine.
I took the car back a few days later and the garage said they could not hear a noise, but would check it over. They found nothing wrong and said the car sounded better than most of the diesel Civics they see.
I was not happy, so they suggested I take the car to another Independant garage nearby for a second opinion.

I didn't expect this guy to find a problem either but he described the noise as 'hissing' and thought there was a leak on the boost pipe. When he had the car in for a propper look he found nothing wrong, but now thinks that the flywheel pickup sensor is 'out' causing the engine management to inject fuel incorrectly. He suggested taking the car to a Dealer to get it adjusted.

I went back to the clutch place to see what they would do, but they don't work on Saturdays.

I'm not sure what to do now, as I don't really want to have the car tweaked if the problem is a dodgy flywheel, but as I don't know the cars history the car may have been tweaked in the past which is causing the problem now.

On the other had if the new flywheel is not right it needs to be sorted, so should I get the clutch place to get on to the flywheel supplier to see if they have a problem? Even if there is will they admit it?

Has anyone else had a similar problem?

Any help would be greatly appreciated.

Sorry for the long story!

Ian

The mechanic is talking about the start of injection.
If its too early you get more power but more clatter too.
Weather can cause this.among other things..not necessarily the clutch.

Go out at midnight when its cool to check this 1st.

Soi works off the cranksensor AFAIK.
The pickup sensor would probbaly be for vehicle speed.

The mechanic seamed to think the trigger on the flywheel was out a bit and that was what was causing the problem. Can Honda dealers tweek the engine management for that?

The noise is there all the time, but it does seem worse when the weather is warmer.

Like I said they dont use the flywheel for the engine firing/injection.
They use the gear behind the front pulley and the cam sensor ;)

Ok, I'm with you now.

So it's not likely replacing the DMF caused a problem with the crank position sensor then. The noise is there all the time since the clutch/DMF was done, so I guess it needs to go to a Dealer then.

Thanks for clearing that up.

Took a while, but I finally got this sorted.

The car went to the dealer who diagnosed the problem at the second attempt. It turned out to be that the grommet around the steering column where it goes through the bulkhead was not fitted correctly and was letting exhaust and Turbo noise into the car.

So a cheap fix in the end, just a pity it took nearly 2 months to find it.

Hope this helps someone else.

Thanks for the update.
Ironically chip had the same issue where someone forgot to put a bulkhead grommet back in.

Hi - could you take an image of your footwell to show me how yours looks? I think I've got the same issue - is there a way to send images on this forum?
