So I'm getting codes P1561 and P1562, I pulled the cover off my IP and tried seeing if it would do the sweep. I only came to realize that it was like spaz sweeping. It moved back and forth numerous times before stopping. The QA is not gummed up it looks really clean, the car stutters between rpms 10-20, and the car has shut off a couple times when driving, oh and also my glow plug light is flashing. All the wires look good, I'm a new vw owner and I'm just stumped because I just don't know whats the problem?

PS: Car reads 3.2-3.4 mg/str

So he has a 2002 Jetta which has been sitting for a number of years, he just recently put it on the road. He has put at least one tank of fresh diesel in it , changed the fuel filter checked the fuel tank, it’s clean, and sending unit, also clean. The car is an auto.

He does have vcds and ran a complete scan, the following engine codes showed 17969, 17970, 17978, 16786, 18057.

Also vcds will not connect to the brake module. I had him check fuse #9 and even swap it with no luck. He does have the abs light on. I’m 5 hours away so I’m not where I can actually see what going on. I told him he needed to check with you guys I’m likely missing something obvious.

For the QA codes, I would follow the guidance in the link I posted, starting with checking QA resistance. Logging it might also provide some insight.

Unfortunately the ABS controller is probably dead since the fuse has been checked but it's not communicating with VCDS or the ECU. BTDT.
