hi guys, probably in the wrong place but i have a problem with the 300sel ignition. ignition switch vandalized, steering lock on, key wouldnt turn into first position to release steering lock and has been broken off inside the lock. any ideas of how to extract the ignition barrel and how to get the black palstic wire container plug at the end of the barrel to pull off? is it necessary to extract the whole unit from the car? if i'm in the wrong place can someone bump me to the right place please?
