Oil leak

danyalmakda · #1 10th February 2023, 01:18 PM

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

Does anyone know where to get gearbox sump pan screws from?
The Zf kit does not come with screws but the meyle kit does
My screws are all rusted so thought I would change them
Thanks
Still awaiting my diff seal parts

Original part number is 01V321373 (27 required). Superseded part number is WHT000747 (M6x20) and you can get them from the dealer, around £2 each. They were used in Audi's up to 2018, so should still be available from the dealer. I also checked multiple listings on eBay and they are selling at around £10 each!
