Hi forum members, I was wondering if any of you have experienced this before. The title says it all. 2003 jetta manual ALH. I had 1 bad gp code and decided to get a whole new set of 4 Bosch, new oem harness because the old one was coming apart, after this none of them worked. New harness wires tested, they should work. I tested the fuses at battery, unplugged the coolant temp sensor, still nothing (other than longer glowing light on the cluster). I've read the gp testing thread, even posted there, no answer. Got a brand new Bosch relay, still no power at the harness. No clicking heard from relay either, so my only guess left is the ecu... How could that go bad at the same time randomly?
Thanks for all the diys, helpful posts, I've been reading the site for years and it was time to post.
