2002 S500- shifter stuck, abs light on, brake lights on..

[kevinrea]

Hi guys I have a 2002 S500.
The problem is the brake lights are on, the ABS light is on, and the shifter stuck in park. I've have it over at the indie Mercedes mechanic, and the shifter is fine, and the plastic piece inside the shifter is ok, the solenoid in the shifter is OK, the brake light switch on top of the brake pedal has been replaced but things are still messed up.
Even with the wires for the brake light switch temoved, the brake lights are still on.

I can tell the mechanic doesn't have a clue.
Anyone else have any ideas?
I've looked all over the internet for clues, and it keeps coming back to the same things, the brake light switch, the plastic part or solenoid in the shifter.
Also, no evidence of water intrusion anywhere.

Any other ideas?

Thank very much.

Out of my depth! Iveranol often has good knowledge of these later era cars.

I would guess this maybe an issue with SAM module rather than a simple hardware issue.

See I was right!
