We have an issue with the 05.5 Jetta TDI starting on cold mornings. It always starts but it cranks very slowly (with a new battery) on 20F mornings. I am afraid it will strand my wife eventually - even if it sits unused for 2 days it barely starts in cold weather. I took my multimeter to the fuse boxes and found a 2 amp drain on fuse 15 inside the cabin (7.5A fuse). Using the bentley manual I referenced it to the vehicle electrical system control module (J519) which is apparently up underneath the dashboard.
A couple of questions - is 2 amps (19.9mV through 7.5A mini fuse) too much static current drain with the car turned off? Key not in the ignition. Vagcom shows nothing pertinent. If it's too much current drain, what on earth do I do now?
