Oil leak
Probably asked many times and a very vague question
Not a mechanic so not sure Leak dripping around sump area Managed a quick look under and the sump bolt looks very rusty and so do the bolts that seal the lower sump up Also bit of oil around the right of the sump? on front diff? Gear box? Have no oil warning and checked levels are all good so far. It has had this long life service so I’m assuming no one has touched any serviceable parts Looking for a mechanic around Leicester area who would be good with these cars? Any recommendations would be great Thanks

I'll bet it's the final drive output seals.

Just had my mate look at the leak
Looks like the driveshaft seal on the drivers side - any particular brand I should go for?or any part numbers? Also need a passenger side CV boot. He does advise the my gearbox sump pan is rusty so might be worth changing- any advice on where to get a sump pan and a service kit for the gearbox? Thanks in advance

All the parts you need are on autodoc and spare parts catalog is on 7zap.com
For stuff like output shaft seals etc I would only use genuine vag. For the CV boot i used LÖBRO on mine, have 3 sitting on the shelf just in case the others get torn, they are on autodoc too. If you gonna take the gearbox pan out, you might as well service the gearbox, once again autodoc has a kit. You can get a second hand sump and get it powder coated, a new one is probably available from TPS/Audi tradition for a lot of money so not worth it.

Thanks for the info
The only problem with AUTODOC is the delivery time - still waiting for my washer reservoir pump My mate said he could get it done this week if I get the parts Will fix the diff seal and cv boot Will attend to the gearbox sump at a later date
