Hello everyone,
When I purchased my A8 D2 2002 3.7 sport 2.5 years ago the gearbox was 100% dry. No leaks at all. I changed gearbox oil at Reading Audi as soon as I purchased car and everything was dry for at least another couple of years.
Yesterday I got under car and what I surprise: 4 leaks! All three output shaft seals + input shaft seal (not sure if it is engine or gearbox though).
All 4 seals -- is this coincidence? Is this a sign of major failure? Car drives tip top. Well, gear changes are not 100% smooth, so yes we have some small sings of age, but I think it is not abnormal.
I have long term relationship with this car, so what would you recommend? I understand I'm looking at gearbox out job and that means exhaust out too. Because gearbox is out will it be wise to completely overhaul it? Or should I just relax and keep on killing the gearbox until it fails completely and then start some planning
Should I have an appointment with a ZF gearbox specialist to take a look at leaks, test drive the car and advise?
Your comments are very welcome.
