2002 clk 430. my car suddenly won't shift out of park. I had no indications, malfunction warnings that there was a problem prior to this happening. Also now the ABS and BNS malfunction warnings are displaying, clearly they are related but would a brake problem stop a car from being able to shift?

Its sounds like the classic case of the stop lamp switch going bad,you step on the pedal,esp sees a difference in the pressures at the booster,but doesnt actually see the pedal moving because the switch has gone bad,also causing the vehicle to not come out of park because this vehicle is designed to not come out of park unless the key is in position 2 and the brake pedal is depressed.if you really need to get the car out of park to get somewhere,on these models i believe there is a flap of plastic just below the d on the shifter panel that has a spring on it,just put a thin screwdriver(i.e.-pocket screwdriver) and least 4 inches long,press it straight down and pull it out of park-with your foot on the brake pedal of course)get this fixed asap-drop the panel under the dash,under the steering wheel-on the brake pedal assembly,theres a part where the switch goes,get the part before you start the job and youll recognize it right away,depress the tab and turn it clockwise to remove it,on the new switch,pull the detent switch all the way out before installation,put some type of bar between the seat and the brake pedal with vehicle on and adjust the seat to press the pedal down and keep it down,install the switch and release the pedal slowly to push the detent switch back it,once its all the way down,grab the pedal by hand and slightly pull it towards you,it should click one more time,now its adjusted,put the panel back on and your golden,just saved about $200 bucks in diag. and install labor-good luck bud
