Hello everyone, I own a 2011 X5 35D. I purchased it as a CPO, it was 2 years old at that time. It has been a great vehicle for me and now that the warranty has expired I have my first issue which i'm hoping you guys can help me with. Two weeks ago we had a real cold freeze here in LI, NY. It was 10 degrees for 2 weeks straight. I don't drive the car everyday so it was sitting for about a week before I tried to start it. It wouldn't start, message came up about the battery being insufficient, I cant remember exactly what it said. It made sense because it's the original battery coupled with the cold weather.

I purchased a installed a new battery, 13.6 volts at install. Registered the battery with Carly. Car didn't start, all I get is a click. I tried grounding the vehicle with jumper cables, nothing, removed IBS and tried it and still nothing. The constant message I get before I try to start it is to please wait: preheating. My question is would a bad glow plug module cause a no start? I am at a loss here. I though the module came into play if its colder than 40 degrees which it has been in the last few days.
