I drove to my purchase dealer today for my 20K service.
My local in-town delaer wanted me to wait 4 weeks for an appointment, and this out-of-town dealer took me right away.
I have been back here 3 times for scheduled service, and they are very good.
I get unprecedented access to the service guys, and the Audi tech. He lets me watch the process.
Here is a shot of the special wrench they need for removing the Haldex plug.

This is the removed plug, with integrated filter. This whole unit is replaced.
It's about 1 1/2" dia.

Here's a shot of the wrench in place. It's tricky to get into place.

Some oil came out the top when he removed the top plug. Another drain hole is here, about 3/8" dia. drain plug, that is on abt. a 2" stud.

Here he is fitting the top plug back in place.

He used a 'gun' similar to a caulking gun, with a removable plastic screw-on tip, thet the oil is squirted in from the bottom drain plug.

That was pretty much it. He did an excellent job of cleaning the car, underneath also. He changed the oil and the HEPA air filter. I can't seem to get him to keep his fingerprints off the rest of the car though.

 

It's there now, yea, I missed it in the orig. edit

 

Thanks!

 

Thanks for the pics Jeff. Totally kewl of them to allow access like that.
