Recently purchased a 2013 A6 Avant 2.0 TDI (private), after a few 100 miles one of the injector clamp bolts came loose, have removed this to find about 5mm of thread stripped and intact in the thread of bolt, replaced the bolt with a new one to get the car running and seems to be running fine however I am weary as obviously there is now less thread to retain the new bolt. Does anyone know how deep the thread is for the clamp retaining bolt and do you think I should get this professionally repaired. I am assuming this will be something similar to a helicoil insert. Any help/advise would be appreciated, I am also interested to know if anyone else has had a similar issue and a rough guess as to how much i could expect from a garage bill.
So I have my Audi A4 Avant tdci and all is good. But what I would like to know is how to set the car up so that when it starts that the gears are set to E mode so it displays E1, E2 etc. The only way I can gwt it to do this is to change the drive select to economy every time, and its a bit annoying.
Otherwise a great car, heated seats where have you been all my life, just like a leccy blanket. Thumbs up 👌🙂
The engine judder could be caused by any number of things, but a rusty exhaust is not one of them. The judder must be bad if it cracked an engine mount, and may also be responsible for a cracked exhaust.
The steering wheel wobble is most likely the road wheels are still not balanced. Have you hit the kerb? Other causes are worn steering or suspension joints, or loose bearings but as they are all MOT failures I hope the dealer has checked them.
Fluid of any sort should not be leaking onto the exhaust.
A stink of petrol at the rear of the car suggests a faulty breather, a leak from the tank, or a poor seal at the filler cap.
All in all you have bought a dog. I suggest you return it and demand a refund.
