I used the chain replacement kit listed on Deutsche Auto Parts as a rough guide to what I should expect to be replaced and they do not include timing gears in their kit. I asked LVS to check for any other worn parts that might need replacing while there was access to them so I can only assume that the gears themselves were fine to be reused.

Thanks for the info. Interested in your new block 93 values when you get them. Will be taking mine over the week end. I am based near Lincoln so it was also of interested where you took your car.

Checked block 93 this morning and I’m now reading -1.36 with the new chain on, so back in to the good zone according to the briskoda thread. Remember to check the value at idle when the engine is fully warm.

Fantastic reading. New chain has worked well. Would be really pleased with that value. Thanks for the reminder about warm engine. Been struck down with manflu  :sick: so the test will have to wait a bit.

Finally got out today to go shopping and did the VCDS check at the same time. Block 93 value is -1.78 at idle with a warm engine (90 degrees C) and revs 760rpm. Seems I am OK at present but might get the tensioner visually checked out through the inspection hole to see how many teeth are showing at the next service.

Sweet, looks like a healthy chain then. Deffo worth the physical inspection through the hole to check the tensioner extension and revision. Block 93 is only an indicator of chain wear as far as I understand it, it won't help in checking for possible tensioner issues.

Yes pleased with the figures. Thanks for the heads up on the tensioner Seabrook132. Not long to the service so will get the tensioner checked out then. Might replace it for peace of mind because I think mine is the original.

So i think it has finally happened to me :(

Got the rattle on startup and sounds like a diesel engine. Had RAC out and they plugged cpu and got can’t remember the exact codes but guy said the time is off which might suggest problem with the timing chain.

Weird thing is a lot of people noticed the problem for the first time when starting their cars. I was on the M1, dropping down to 4th and then when I put my foot down there was no power. Still managed to drive but nowhere near the acceleration. Only when I got home I noticed the engine sounded like a tractor.

Going to book it in with VW tomorrow. Does anyone have any advice on how I should approach them? I bought it from this dealer two years ago and have had a few issues with it already. Engine still started so I’m guessing it’s not a total rebuild? Hoping it’s not as bad as that!

Thanks

Check out page 56 on this thread, your symptoms sound very similar to mine a few years ago. My chain had stretched, required a new chain (revised part), tensioner  (revised part), guides  etc etc.  Also see page 14 for my previous tensioner problem a few years earlier with part numbers etc.

Good luck

Mike

Thanks Mike, vw mechanic looked at it today and confirmed stretched chain and the tensioner has gone - just like yours. Going to give me a quote in the morning of the work but already know labour is £140 per hour!!! Said need to check if anything else was damaged. I just want to get rid now, very bad experience of buying a used VW
