I'm a former Scirocco owner as I see you have/had a Gen II version. Actually had two identical (only the factory radio ***** were different) 1980 Alpine White Scirocco S vehicles. One was totalled after ten months so I got an identical replacement. The '81's were out but they actually detuned the horsepower a bit to improve fuel economy and I wanted none of that.

The photo was taken in front of the defunct VW Westmoreland County Rabbit/Golf assembly plant in New Stanton, Pennsylvania. At the time VW's only US plant. It ten closed and there was none as they started to create one in the carcass of a never finished Chrysler plant near Detroit. They halted it in mid-construction.

I sure miss that car.
yeah, i still have it!
it gets used way less used than it should, but i don't think i can ever sell it. i have a life
sentence with it, no possibility of parole. i just wish the audi was as simple as this thing!

a nice mk1 S would compliment it well though. that's the dream. one of each!

Default This is one of the reason why I don't use VCDS only when the car dies

arghhhhhhhhhhhhhhhh
What's the purpose of running the output tests? You don't have to get your money worth out of the VCDS by coding? I paid $350 for it and only used it about 4 times.
Most of savvy VCDS users screwed their cars up more than the ones without.

I don't even clear the codes, as long as everything runs without warning lights, it's fine.

Cheers,

found the problem.

famous wiring harness corrosion. i see that it has been fixed already once with those yellow dealer
replacement wires, now it broke further back. i traced the wires and replaced it pretty far up the harness.
you would just touch the wires and they would turn to dust.

Do you recall how far back in the harness you went before locating the damaged section?

Just keep in mind that under the worst temperature and humidity conditions, water can wick 3M in wiring. That's why it needs to be sealed at every connector or end. If the insulation jacket gets compromised, the corrosion travels in both directions
