EPC light comes on dash when I start the car and stays on now. I cleared the code with Vag-Com and it comes right back on. Happened after pulling stuff out of the way of the valve covers to apply Loctite and re-tighten nuts to fix oil leak. Everything is back together. The only other recent work was replacing left front inner and outer cv boots.
Someone mis-advised me that the EPC followed by that code was related to an incomplete circuit to ABS sensor, so I cut the cable and re-wired it in the wheel well where I was replacing teh cv boots. I did stretch the cable when removing the upper control arms to let the hub move out to get the cv joint out so I thought that made sense. It did not fix the issue.
Drive by Wire-MIL Circ. Electrical Malfunction. Although by the description, this sounds to me like it would have something to do with the electronic throttle control or something, a little searching of forums for this code came up with someone suggesting to check for leaks in the intake system. This reminded me that I did find I had left the PCV connector off of the Y pipe and I drove the car for a day like that. Once the EPC light came on, I looked around and saw that connector off & re-connected. Cleared codes and EPC comes on again. I'll check around for leaks, and build this leak tester: http://www.awe-tuning.com/media/pdf/...ure_tester.pdf
Thanks, so according to this, the instrument panel has to come out and the module fixed or replaced. The Passat World forum you linked showed it as a "Power Accelerator Fault". Others indicate it has something to do with the air intake system, and at least one source pointed to the faulty ABS circuit.
I'm confused by the wild, all over the board trouble code descriptions. They could have you tearing apart 5 completely different systems in your car to chase a single trouble code.
It seems like starting with simple checks (intake leaks) and moving toward more complex while following the meandering path of these fault code descriptions and recommendations is the only path toward resolution.
I can pretty much guarantee that if this problem lies deep within the instrument cluster, I'll live with it until I sell the car or the car stops running.
You strike me as more of a Jeep guy. Fault code, ergo part must be bad, replace parts until problem solved. I've never heard of anyone splicing the ABS wheel speed sensor wires. Has anyone else? Have you checked for fault codes in other modules? Have you replaced your battery with a known good one? Checked all connections?

Splicing the ABS wires was done out of frustration after 2 weeks of back to back problems with the car. In hindsight, I should have had more patience. No, I would not drive a Chrysler product if it was my only option. And I do know someone who repaired a broken ABS cable that cracked and shorted at the strain relief by splicing in a shielded 4 conductor wire.
Here are the complete fault codes scanned a minute ago. Note that the drivers seat memory has never worked:
