Those values, even the "improved" ones don't seem right. I can cruise at 68mph along A roads for approx. 35 miles and achieve ~75mpg, if I push it, I still get ~65 mpg, according to the trip data. My only gauge is I had a A4 BB 2.0 diesel and for the same amount of fuel and journey, I'm now getting ~100 extra miles per tank. I only use Esso standard fuel with the required dose of Archoil. There could be something more sinister going on there. Edit: what's the service history? I changed the air filter and spray cleaned the MAF sensor shortly after getting mine, but I don't recall the MPGs ever being as low as you're seeing. I also think my car has the latest version of software.

The DPF cleaner will not solve the issue. The issue Is the EGR cooler, unfortunately.

That's broken from the radiator mate. You need to replace the radiator. There's no way I'd be driving that 15 miles, get it towed.

I bought a 12 year old focus several years ago with 50k on the clock original timing belt, sold it to a friend who put another 60k on it over the space of several years. He never had the belt changed. He sold it back to me in 2021 cheap, so cheap I give it to my ex girlfriend who needed a car, anyway to cut a long story short she sold it last year with over 120k on the clock and I see it on Facebay a few months later with a suspected snapped belt! The car was a 2005 model so the belt lasted well past its use by date and recommended mileage. I've seen a few manufacturers giving two intervals lately I.e 80k warranty and 120k out of warranty. Personally I've always done the belt on the cars I care about on mileage alone and not had a belt snap on me yet. I think someone that uses their car alot is gonna hit the mileage long before the belt is considered out of date and those that don't use the car a lot don't do enough miles for the belt to be that badly degraded in the time frame.

This is illogical to me, and I believe it is engineeringly unsafe, and wouldn’t be for me. While noting David’s - Itspointless- comments, I’m afraid I would have to counter the view that …’so age isn’t an issue’. It can, and is indeed an issue. The ongoing serviceability of a completely unstressed belt stored in a box for say 5 years, cannot be compared with a fitted belt which has been subjected to hundreds of highly stressed stop/ starts every week, sometimes in sub zero temperatures. If (in caps) Audi U.K. and I then guess Audi Global ( rather than a dealer) are saying there is now only a mileage limit, then how many of us doing short but regular low mileage trips around town etc. would be prepared to chance our engines ,when running on a 20 + year vehicle? Darren’s dealer’s phone call is interesting, and I’m not sure whether it was an out-of-the-blue call, or it was as a result of Darren having made a prior enquiry -? Audi economics?? Profit is made by the Audi dealer when fitting new belts and VAG make a profit on resale of the belt kits manufactured for them. However, if a belt fails, the potential for revenue is considerably higher where the vehicle is declared beyond economical repair and has to be replaced, or a very expensive engine replacement arranged - potential for far more profit! Now the Audi Economics makes logical sense - to Audi!! Sorry folks but it still doesn’t to my pocket. Additional point to consider - renewing the auxiliary belt -? I can see this timing belt scenario becoming an ‘inherited issue’ for buyers in the future, as the baby is passed on as the purchaser’s responsibility. Kind regards, Gareth.

I know on my A6 2.5tdi it's 8 years. Which has never been a problem.

Well it seems after a visit to audi and buying a genuine oil filter! The union is part of the filter itself, no more filters from ebay I guess. Oil pressure warning has stopped.
