Default Re: SMG Gear Position sensor?

The 87 aktions modi is a new code but I have been gettting the precat sensor.
I thought I read somewhere along the way that it was best to perform the diags on a cold engine, but I've read so much in so many threads lately that it's no telling what I read. Haha

The clutch control code is new, but the gps codes have been existent.

The only time I know of that it might have not cranked is during the adaptation process when it asks you to "hold brake down and start engine." At that point, I'm assuming that it was in a different gear because I had to turn the car off completely and then right back on to get it into neutral to crank. I didn't realize that I should use INPA to shift into neutral. That would save for any disruptions from having to turn the car off during the process.

An older thread but did you find resolution? I've been through a nightmare of smg pump replacement, relays and a new clutch and it's in the driveway and what i have left i think is the GPS.

It did end up being the gps. I was able to change it in the driveway using jack stands and ramps. After putting the new one in, I ran the adaptations and everything has been fine ever since.

How bad were your symptoms? I put the new pump in and before the pump i had some lag that i wasn't sure if was clutch/pump or just pump. After the pump i still had lag so i thought clutch going, finally i got stranded after some spirited driving that had lag and then finally stranded me in N. So i had a new clutch put into it and it wouldn't program and sat at a shop for two months. I finally got it back and after being beat up on the previous stuff let it sit. Now with inpa i was able to get it to program to a place where it will shift super slowly but not good enough that i'll trust going on the road. When it does shift it can be very violent as the clutch won't engage until it lines up and then BAM. I can mitigate this by keeping revs down (this is all 2am driving tests around the block with no traffic). Did you have any lag symptoms or similar?
