A7 PPI problems
Hi all. I have finally found what I think is my next car. A 2015 A7 Prestige. But the PPI at Audi revealed the following.
1 The oil drain plug is leaking. Is it common? Could it be just the crush washer or is it possible the threads in the pan are bad? Is there a simple fix for stripped threads? Heli-coil maybe?
Can the lower pan be replaced without dropping suspension parts?
2 the back glass sensor. Someone tinted the back glass and may have damaged heater wires. Can they be repaired? Is it possible to remove tint without further damage?
It has a bad motor mount but that is covered under warranty. Any advice is greatly appreciated.

An oil drain plug leak is never common. It could be a bad crush washer or stripped threads. First thing I would do is to loosen the plug a few turns without removing it and retightening it. If the threads are stripped, you would feel it. If the threads are stripped, I would replace the oil pan. It doesn't look to be that hard of a job. It can be replaced without removing suspension parts.

Tenspeed is spot on. Even if a horizonal defroster heating line is bad, its not a big deal. You may never notice it. I remember the tape and painting fix, but that was 30 years ago.......
Is the oil drain plug really leaking? Or just a wet weeping? Maybe the last numpty who changed the oil reused the oli washer or forgot the washer altogether. Due to accessible location and size, its not easy to cross thread. What do the service records show on who did the work? Audi dealer or jiffy blupe.
If i remember correctly, the pan is cheap, just pressed sheet metal. Easy swap. Must use new o ring for the Hella oil sensor on the bottom.
