I just finished putting the motor back into a 2002 A4 1.8T and I don't remember where three ground straps bolt to.

One of them is on the passenger side near the bottom, its a short one by itself about 8 to 10 inches long, its bolted to the frame and the other end has a lug and is attached somewhere with a nut and bolt.

The other two are on the driver side and car connected one side has a metal tube around it that bolts to the tranny i believe and also has a plastic connector with a single femals spade connector and then the other end of that cable has a lug on it.

If anyone know where these go your help is greatly appreciated. If pictures helps understand what I'm asking let me know and I'll get some pictures posted.

 

yea pictures.... i know what u mean by the passenger side one.
