Evening all,

Had the Z3 MOT'd and serviced today, sailed through which is always nice to hear. The car is still at the garage as I'm picking it up tomorrow morning, however on the phone today they mentioned the timing chain is stretched and could do with replacement, but they would chat to me more about it tomorrow. A quick Google shows that 90,000 miles is about the right time to replace (my car is on 97,000), so it sounds reasonable enough.

Does anyone know roughly how much I should expect to pay for replacement?

Thanks in advance.

Thanks all, always good to have a second opinion.

So it's possible to simply adjust the tension of the chain? Also is it easy to identify if it is too slack?

Used the garage for years and also a good friend of my parents works there, so I'd hope they wouldn't try and pull a fast one, they've done a few freebies for me before etc!

Also I spoke to the receptionist who may not have gotten the full story from the mechanic, so I'll have to see what he says tomorrow about it, it might just be a case of letting me know it's not as tight as it could be? I'll have to report back smile

Right, got the car back now all serviced and MOT'd.

The engine management light was on (I thought it was related to the servicing becoming due but obviously not), and the source of the error came from the sensor for the chain. They're not going to do any work on it at the moment or without a thorough investigation of what is causing it, but they said a possible cause is the chain becoming stretched and therefore knocking the timing out a little and confusing the ECU in to over fuelling?

Anyway, all error codes reset and light turned off, now just going to wait and see if/when it crops up again and then diagnose from there.

OK thanks for the extra info. I would certainly suspect the camshaft position sensor being duff rather than the timing chain.

Is it an easy DIY job to replace? If so, and the light comes on again I would rather replace that seeing as it's a much cheaper possible fix.

Also anyone know of a good specialist around Notts? I'm not in East Sussex if you are referring so some garage with a bad reputation?!
