Hey guys, new to this side of hatches. Had a speed 3 previously. Anyways here’s my egg, don’t know much about it other than it has a backyard built engine and a big turbo making 600 on e30. I’m having an issue with the dsg unfortunately the car only has 1st and 3rd gear, no reverse. I was told by previous owner mechatronic unit needs a relearn, is that a thing or should I just replace the transmission as a whole? Apparently it has a new mechatronic unit in it.
