CLK 500 ABS Speed Sensor.


Hi. I recently took my car to a mechanic and he replaced the ABS Speed Sensor. After the replacement, I have a ABS and ESP fault lights on the dash. I also cannot shift out of park now. Any idea what the issue may be? The car is a 2006 CLK 500, no fault lights in the computer, the mechanic also said they tried resetting several times also. I might have to tow this thing back to them to get it fixed. Thanks for your help.
