more and more frequently, i get in the car to start it and i notice that the clock is at 1200. the trip odometer is at zero. the overall odometer reads the mileage. turning the key will make( on occasion) a ticking sound. not always. after turning the key on and off several times the car will start. this is a tdi by the way. if i don't get the glow plug light, it won't start.

battery discharges overnight
fans keep running after the car was shut off. He started the car again, got the fans to go off, but it still drained the battery somehow. Have not been able to figure it out, or get it fixed
My GPS/radio doesn't work. I smell electricity burn then it went dead.
This is a 1999 Golf Automatic (Gasoline.) The car will not start despite charging up the battery. The starter will click but will not turn over. Te rear window wiper will not turn off when switched to 'off'
The engine would cut off completely in random locations but most notably in the fast lane on the highway. The wiring harness had to be replaced for the engine and it was covered under warranty.
Serious draw.
front and rear light bulbs burn out too often
