03 ml350 ESP BAS light on stuck in park
Proud owner here... well, I was for the length of the three times I used the damn thing. Last time I drove it everything was normal, no light on. I parked on my driveway for two weeks (we got lots of snow and very cold weather). Yesterday, cranked and started right up, press on the brake pedal and the esp bas light came up and the shifter would not move out of park.
Turned the steering left to right full lock, the light went out (this tells me my column steering sensor is ok). Stopped the engine, cranked again, as soon as I pressed the brake pedal the esp/bas light came on again. I could notice the rear brake lights illuminated...
I guess I'll need a scan to really know. Are there any scanners which I could get to scan for these issues or I absolutely need to go to a dealer/indy?
If the car never moved can I blame it on humidity/corrosion on wires/connectors alone? maybe a bad esp relay or low voltage to the circuit because weak battery? (it did cranked very healthly).
I understand on my model year I do not have the brake pedal switch, it is instead a brake fluid pressure switch on the master cylinder. Can that one be bad and still have the rear brake lights working?
I can use the pen trick to unlock the shifter and maybe take the esp off. Can I drive like that around?
Many thanks for any input and sorry for the long post
