Hi everyone New on here and need some advice.... i have 2001 Mercedes C220 cdi auto 84k, the remote key unlocks the car, mileage display lights up but when i put the key in the ignition nothing happens it doesn't click or turn. battery is ok the headlights turn on & off, remote central locking works on both keys. I've had a booster on the battey to give it a kick start but still nothing. the car was running fine prior to this, i'd only parked it 10 minutes before the problem occured. Any help & advice will be much appreciated. thanks in advance.
