Hi everyone I hope anyone would be able to help me out . I have a 1.8T Jetta 2001.Ok, this is what happened; I was TRYING to get a readiness code out my VAG-COM, I was on step 3; Matching Throttle Valve Control to the ECM, I couldn't hold steady the gas pedal, although it came out "ADP OK" and by the time I was about to begin step 4 the car went crazy and began to idle between 300 and 1000 rpm's back and forth without stopping. I hit the gas and it just died, and I noticed a huge gasoline smell. I checked for DTC's and it came out with;P1558 Throttle Actuator Electrical Malfunction
P1579 Idle Speed Contr. Throttle Pos. Adaptation not started, and P1545 Throttle Valve Control Module
Yeah, i swapped the Throttle Body with another one I had, but the same codes still were there, and no chance for erasing dtc's. I replaced it again with the old one and began checking on the electrical, I came across with the Power Supply Relay and unplugged it and plugged it back and all of the sudden all of the warning lights went off, eg EPC, Engine light. I went and erased DTC's and aligned TB and and turned on the engine, and like nothing would've happened!!!. It threw a Misfiring code which I erased and never came back and for a week the car was running even better than what it did before (probably for the fact that I cleaned that TB too) but after a week, it died again (EPC, Engine Light and that other signal that has a circle around it, they all came back) and this time i haven't been able to get it going........on block 60 it shows 15%, 84%, 0, and on the last one, instead of reading adp ok, it reads ERROR. I got a new relay thinking that could've explain that weird resetting that fixed it the first time, but that didn't work!!!...I also disconnected the 6 pin con from T Valve Control and it shows the 5V of the of 4.5Vmin required..............
I am thinking is the ECU and not anything else because the car ran fine for a week AFTER it threw those codes, but I barely know how to change the oil on my car , so if theres ANYONE OUT THERE, please I NEED HELP
Thanks!!
