Battery drain on merecedes e320 2003 - 2003 Mercedes-Benz E-Class

this usually happens when you change out the battery. Our have loose connections.

besides using a scanner to reset the immobiliser ,I would have a load test done on the battery as lights are a false indicator of the battery condition. The starter draws almost all of the cranking capacity of a battery and faulty cells while supplying low current to lights will not turn a starter motor .

ARE YOU BLIND?

The upper mounting bracket of these are known to corrode and fall apart. I am glad you were not driving when this happened. A weld shop may be able to repair and replace the spring after repairing.

You need to disassemble the door to extract, unless you are speaking of JUST the key portion of the lock.

I had a similar problem with my car and was advised that the ESP and BAS normally come out as a direct result of the low voltage on the battery.Chances are your battery life has expired. Replace your battery with a new one. To remove the ESP you need to start your engine, turn the steering wheel all the way to left and right, repeat this a couple of times, switch off and restart your car.Make sure you don't leave your lightsand wipers on the auto position as this sometimes drains your buttery power unnecessarily. These simple steps should take away the frustration and make you enjoy your car again.

make sure you have power in the changer, check connections, by unpluging and pluging back.
