MCPaudiTT - DEFCON 1

A relative easy job, not on a maintenance interval. My fluid was darker that new, and there was minimal build up of metal (wear) flakes on the magnetic drain plug. Probably not a real need to do it, but not too expensive, so what the heck...

Open drain plug (17 mm Allen):

Drain fluid (it is "motor oil" and can be recycled with normal engine oil):

Clean the drain plug of its flakes:

Replace drain and open fill hole (17 mm Allen again):

New oil (available at VW as well):

Pump in a new liter of fluid, plug the hole, and you're good to go:

Hi, I did mine a few days ago when I was doing the haldex oil change and fuel fitler. Nice write up.

Has anyone done the front differential bevel box? Isn't it a similar differential and need oil change too?

Make sure you can open the fill plug BEFORE you drain the fluid.

I did have that thought... AFTER draining the fluid! ; )

3.2 DSG bevel drive oil is separate from the transaxle oil. Other than having to refill separately, the procedure should be the same as the posting. Audi lists a special oil, but as far as I can tell MT90 should work.

those IMO, and not a good place to "risk it"...

I would also bet the DSG does not use an Allen plug - even later TT's have a different shape (triple-square or Torx - I don't recall).

There's a seal between the two sumps.
