Title: Battery Draining
Post by: MadDogMare on September 19, 2013, 04:16:31 am: Hey

I've got a battery draining issue with my 2005/05 GT TDi. Original I thought it was just the battery, so got a new one... but turned out I had a faulty switch in the brake pedal that caused a brake light to come on at night(...?) (strip light on the spoiler above the rear window)... so, got that fixed. Couple of months later , guess what, battery totally drained again... had RAC test the alternator this time too and all is fine, I've checked all lights (boot, cabiole, mirror and so forth) . After reading a couple of the threads on here I came to the conclusion that it might be the Can Gateway thing. Any advice? :confused:

Then see if it's a module fault causing the issue.
