I own a 2002 VW Jetta TDI. My GPI is flashing and can't figure it out. I scanned it for trouble codes and it shows none. The temp. outside is around 90 and I have checked the GP and checked and cleaned the connectors. I have noticed that pre-fire on my glow plugs is a split second(like a half second). I have checked and replaced my brake light bulbs. If anyone can help I would appreciate it.
Thanks,
Steve
