Can someone please tell me where the TCU is located on a 1998 Beetle and the best way to get to it?
Thanks

TCU?

Did you mean ECU? If you did, its like changing the cabin air filter but on the side in front of the driver.

What exactly are you trying to do?

TCM is what I think its usually called (Transmission control module). Probably why FL_Bug wasn't sure.

Yup that is what I've always called it. But the repair Haynes manual I have says TCU so I figured TCM wasn't good enough for VW and they had to change the name.

It would really be helpful for you, and for us, if you'd keep everything in one thread. No need to clutter things up with multiple threads on the same issue.

The TCU/TCM (same thing - interchangeable) is underneath the dash on the right side. Remove the front/center dash panel (it just pushes forward). Then remove the panel to the right. Once you get that panel out of the way, there will be another panel underneath it. Remove that panel, and the TCM will be right there. The only other thing in there is the cabin filter.

Why do you want to access the TCM? Do you have reason to believe it is bad? IIRC, you are having shifting problems and some codes relating to communication problems? It could be the TCM, but it could just be a dirty/bad connection at the transmission end.

I don't have time to go searching through your other threads to confirm this...which is precisely why I told you that you should keep everything in one thread. If I'm going to take the time to help you, I don't want to waste time trying to get the rest of the story or to see what has already been covered.

Yup DZLBUG, you are right I should have kept it on one thread the problem was the original was on the wrong thread. I originally thought it was an engine problem. So I tried to correct that by moving to the Tranny forum.
I had a P0768 code, D solenoid. I checked resistance on all solendoids at the case connector, all good. Dropped the pan, every thing looked great. Since I can't fire the Solenoid and test it I need to rely on restance checks. Once I have the TCU off I can wring out the cabling from there. Then change the TCU and see if that works. If not I will put a torch to it. Not really, I'm just frustrated right now.
