Auto tech with extensive knowledge in subarus, still learning VW stuff.
Recently picked up a 2005.5 BRM Jetta. Began with a no crank/no start. Would come and go as it pleased. Ended up hooking the starter signal wire to a 12v push button so that i can start it when i want and bypass whatever is wrong.
I dont have access to VCDS currently, waiting on my cable in the mail.
So now it starts every single time without fail. My traction control and steering wheel light (amber not red) are constant. The only code I ever pull from OBDII is a P0600, a serial communication failure.
Sometimes, after i start it, i'll have no speedometer, odometer my fuel gauge does what it wants, no AC and my trunk/fuel switches wont work.
Sometimes everything functions as normal. Speedometer works, ac is cold, fuel gauge is constant.
Ive thoroughly read about the BRM engine wiring harness issue, but have checked all of the rub spots that have been mentioned, and never found a single chaffed wire. However, PO hacked up the radio harness. Still have to sort this issue out.
Is this pointing to a bad ECU or some other module that is losing communication? Ive checked most of the grounds and even added a couple to help out the starter.
Pulling my hair out here while waiting for vcds to be able to tell me more. Any help would be greatly appreciated.
