As of course an under engineered part will only give problems in a "tiny" number of vehicles.
Hopefully Audi will contribute towards the repair, though from what I have read they can be less than keen, not unusual for VAG, BMW or Mercedes.
Do some research on American based VAG forums as from memory our American cousins had a bit more luck getting paid out.
The service intervals became like a Chinese harvest.
8000, no 10,000, no 12,000, then 14,000, then 15,000 and now 18,000 on some.
In reality the oil is so dirty at 12k, you are on borrowed time after that.
Police diesels have oil every 8000, just like the old days regardless of exaggerated service intervals.
They know how to get 200k+ out of a diesel engined car
The usual result is premature wear for a lot of engine components but as long as it makes it out of the warranty period it suits the vendor.
People tend to prefer cars with longer service intervals as it appears they are saving money.
Which manufacturers are they ? The VW Group, so VW, Aud,i Skoda, Seat (not sure about Bentley) all say for the average 10,00 a year man change oil once a year . Only for the higher mileage driver do they stretch the service to 18,000K and that subject to control of the monitoring system.
I knew a mechanic who owned a Corsa C 1.2 16v from new and so did their neighbour. On his own Corsa he done the oil changes at approx 6k intervals and if i remember vauxhall recommended ever 12k.
He changed the timing chain at 120k miles on it and said the engine was fairy clean inside.
His neighbours timing chain was rattling it's head off at 80k miles and when he stripped it down to change that, it was all sludged inside a lot of areas with lots of carbon deposits.
His own car was serviced by himself and his neighbours had FSH with Vauxhall up to that point.
There was a few reports as well of mechanics changing oil filters on Corsa Ds with same engines and the oil filter had broken down so much it was almost like a paper mache texture
Oil pressure warning light came on so stopped car. Car was taken to Local vw/audi specialist, told turbo, oil pump, and chain all damaged and engine damaged too around 3k to fix, and car not worth much more so I've lost it. Just so gutted, no warnings or anything..
After reading all the comments on here I'm firing off an email to VW.
