Hi

I have a 2015 facelift Audi Q7 3.0TDI with 70k miles, and I’ve just. heard the dreaded cold start chain rattle last few weeks, almost daily. Cold start only, it makes the rattle for 1-3 seconds. No other symptoms , drives fantastic.

Is there anything I can do to either stop the chain from getting worse ?

Anyone know of a specialist who won’t charge me an arm & leg ?

At only 70k ? has it been clocked or something ?

I'd like to think you'd be getting at least double that before it would be of any concern

From various YT videos, it is no small task. ie. Full engine out job. I'd be near tempted to change vehicle.

How long since it had an oil change?
Certainly something i'd try first with some good quality oil before condemning the timing chain.

I have the same engine in an A4 Allroad. I bought the car at 86k at the end of last year and it had an occasional rattle which didn't get worse but became more frequent. I understand its the tensioners losing pressure rather than chain stretch in my particular scenario. The car has just clicked over 102k.

From the reading I've done on the issue, I was hoping that being a later car it could be cured by changing the top tensioners that can be accessed without engine removal. My specialist advised against this and the car is currently with them to get this sorted. The diesels are generally quite happy rattling away and there doesn't seem to be much info suggesting they actually fail but I personally would rather it didn't rattle.

I'm having a few extra preventative bits done as per their recommendation while the engine is out but I was advised a basic timing chain job (chains, sprockets, tensioners, bolts) would be £2700+VAT - I'd imagine a Q7 would be in a similar ballpark. They seem to do a few of these so if you are anywhere near Norfolk, drop me a line as I would recommend. They've been very good since I've got the car and seem to understand the car better than Audi themselves in certain aspects at least, in my experience.

I've got a Q7 2015 with the same issue
I'd prefer not to spend the money but don't want to end up with a scrap motor
Can you advise of your specialist as i'll be in the Norfolk area in May and would appreciate talking to them
Cheers

Any chance you could point me in the right direction as to who done the job for you?

I'll second this.

Try Motul 8100 oil and also have a good look at the old oil coming out. Use a genuine oil filter as well.
