Hello everyone while this account maybe new, I have been a longtime member of this board and can not thank you all enough for all the great information on this forum.
I have a 03 Golf, and for the last year I have been dealing with this odd intermittent starting issue. The car will simply act like the battery is dead, the gauge lights will dim, when I move the key to the start position and some times the doors will lock or unlock. Once the clock reset the car would start normally. A good friend of mine told me about how there are a few different batteries that are Vin specific. So I simply got a new batter from the dealership and the car behaved it self. He also recommended rebuilding the starter.
This was all good for a month or so and it started again, so I shot a few wires, replaced the 109 relay, cleaned grounds, replaced the ignition switch and replaced the starter. All of this did improve how the car started, the engine seemed to turn over far more quickly. But still after a few weeks the issue comes back. Now I carry the tools to disconnect the battery and after that the car starts up perfectly.
What I have noticed in the last few months the ABS and Emergency brake light will blink on and off with the warning chime going off. When this happens I know the car won't start in a day or two. This has gotten beyond annoying.
Today I was able to time the blinking light issue on my day off and here are the VAGCOM codes.
19456-Glow Plug Indicator light
00668-Supply Voltage Terminal 30, 008 implausible signal intermittent
00532-supply voltage B+ 07-10 Signal too low-intermittent
01331-Door control module; driver side no communication intermittent
01305-Databus for infotainment
While all this to me is pointing to a bad ground, I am still puzzled why the car starts perfectly after disconnecting the battery.. But with another day off, and two hours of studying the wiring diagram I will attack the car full force in the morning!
