Need some help diagnosing a problem
Hello all,
I have a friend who has a 2000 bug with a 1.8 t and a manual trans. She has been having some issues with her car and i am trying to help her out. I do some light duty mechanic work on the side but don't have a ton of experience with v.w. Ok so here is what has been going on a few weeks ago she called me and said her car would just turn off on her while driving and she would pull over to the side of the road and it would restart. This happened once and then started happening more frequently so i went over and pulled the codes there was a check engine light on and an epc light. the check engine code was referring to a poor signal from the mass air flow sensor. so i pulled it out and it looked pretty dirty but instead of just cleaning it i replaced the mass air. Erased all codes and she drove it for about a week with no problems. Well now just the other day she said it started doing the same thing again and it was worse. so i went over again and pulled codes and now im getting a p-1388 ecm malfunction,p-0322 input speed circuit no signal,and a p-0321 code. Has anyone experienced symptoms like this before? Any tips would be greatly appreciated thanks for taking the time to read my post

When found in a VW Golf/Jetta (1J/9M) or Audi A3 (8L) with 1.9l TDI-PD (AXR), check TPI 2007067 which explains issues with electro magnetic interference. A modification to the wiring will fix this problem, extensive details can be found in the named TPI. Even though this TPI was originally released for VW Golf/Jetta (1J/9M), a customer of ours came across the same issue on an Audi A3 (8L).
When found in a 2004 VW Golf, Jetta, or New Beetle with 1.9l TDI-PD (BEW), check for TSB 2010461 (01-07-45 formerly 97-05-03) or 201463 (01-07-44 formerly 97-05-04) calling for a flash update to the ECU and a secondary ground installation.
