Hello everyone,

I have a 1997 E320 with the mechanical key. I replaced the car battery last month and thought this solved the problem. Had some electrical gremlins.

Well my wife came home, parked the car took out the key and car is still running. I disconnect the battery and the car is still running?!?!!! What the?!?! Yes with the battery disconnected the engine was still going, never seen that before! So I took the key and turned it to start the engine again, note I was not getting any power to dash lights, air conditioning etc. And yes it made my starter work and this killed the engine. I am concerned, do this a few more times and I will be buying a starter. Any ideas? need new ignition switch? ECU? any relays related to this problem? Any help before I take this to an independent and grab my ankles.

Thanks everyone!!!
