I have used this on all my diesel vehicles, range rovers, JD tractors, Scania Trucks and a nice selection of Audis. Does what it says on the tin
and noticeably quieter!
my 2018 allroad 272 has the same issue and is going in to Audi to be fixed under warranty. they say the cost of the item is minimal but is engine & transmission out and will take them a week! they said it is a well known issue and have done them frequently.
Staggered Precision Hubcentric wheel spacers in black with Locking wheel bolts, 15mm/20mm for A7 C7 for genuine Audi Alloys can be found here
not suitable for Allroad - thats why they are for sale!
for the avoidance of doubt the car is not included in sale
Had a DTUk item on my BiTdi (313) provided you didn't push it too much it was ok. Unfortunately when you wanted the beans it would sometimes just cut out. Not quite what you needed there. Seemed to regen more frequently too. When it was working it was quite effective.
