Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** sounds like a fault with the brake light switch. When the switch malfunctions it will not send the signal to the shifter to release the shifter. It will also cause the ABS warning lights to come on. The brake lights may still work even when the switch malfunctions.
Let me know if you have any questions. Kindly rate my service when you are done.
The brake light switch can tend to be intermittent. There should have been some fault codes stored in the traction control module for the brake light switch. The next time this acts up you should check the codes to see if they indicate a bad brake light switch.
Let me know if you need anything else.
Can you post the vin number for me?
On this model the brake light switch is located underneath the car below the pedal underneath a cover. If you need instructions for replacing the switch I can send the factory workshop instructions to your private email for a small additional service fee. I've sent an additional service offer with this reply. You will need to accept the offer and reply back with your email address. Normally you will get a fault code stored for a fault with the brake light switch.
