So the battery light came on in my wife's 300td a few days ago. Shortly thereafter, the battery was dead. I had it recharged, it's less than a year old and they said the battery was fine. There's a 3 ampere draw on the battery with the car off which seems very high to me. I took out each fuse one by one and checked the current but it never went down. Is there something i'm missing? Is there another fuse box besides the one on the firewall? Or should I start pulling relays/switches also? I just got the car out of the shop after having most of the a/c system replaced as well as new glow plugs installed. Could there be something related there? Anyways, any help would be greatly appreciated.
