Hey guys. I have a concerning problem and was hoping you could provide insight. I am driving a 2019 RS3 (North America). I did some modifications and am running into a very confusing trouble that I can't seem to figure out. My first mod was JB4 and I ran the e30 map. It worked great. No problems. Then I bought an intake from the 18 model and they changed the DV piping so it was not plug and play. I ran it anyway for a few miles, but decided that having the DV dump to atmosphere was something I'm not comfortable with, depsite it being a MAP sensored car. I put it back to stock intake and did some pulls. I then got a "drive system malfunction" high in the 4th gear powerband. Pulled over and scanned the car P0000.
I turned the car off, the CEL disappreared. Did another pull, and it came back. I took it home and took off the intake to inspect. I didn't see any problems, so I went to put on the intake back and it wouldnt go on. I noticed at this point a kink in the coupler to the turbo inlet from the intake piping. I don't know if it was like that the whole time, or if I kinked it in that moment putting it back on. Can't be sure. I fixed the little kink (air would have been able to pass through it) and took for a drive, hoping it would go away and delete the code. It did not. I did a battery pull to try to clear it. The JB4 wouldn't clear it either. When it came back on, I got the normal CELs from all the drive systems resetting, but 3 persisted and would not clear, and none of them make sense.

I had a friend from VDCS and it couldn't tell me what these faults were either. It said unknown fault. It did bring them up, but didn't know what they were, similar to the JB4. I don't have the log and I'm so sorry for that, but was wondering if someone could shed some light on what is going on with the car? I have since taken off the JB4 and am not getting errors when I drive it, but i know those codes are still there as soft codes because you can tell its in a mild limp mode. The car won't give full boost or launch control when it has soft codes. Trying to avoid going to Audi because of the modifications. Don't want to get TD1 if I don't have to. Any insights?
Thank you so much.
