Audi RS3 timing chain

[JamieMD]

Just looking for a bit of advice on timing chain…mine has got 89k at the minute and hearing a bit of a rattle… can anybody advise what to listen out for? Don’t want to leave it till last minute…I’m wanting to keep it for while so I know I should probably do it soon??? Thanks in advance.

How does the car's history fare against the maintenance schedule? If it's overdue a new tensioner and a rattle has developed, I'd get it done asap.

Thanks for the advice

They usually rattle badly when you start the engine when it's cold especially if the car hasn't been used for a few days. My Mercedes timing chain is on it's way out and after idling for 10 seconds or so the clicking noises start because the oil pressure has dropped.

I don't know about VAG diagnostics but with Mercedes you can read the camshaft adaptation value to give you an idea as to how much compensation is being done
