Hi all just after some advise got a fault with a Mercedes C180 W203 model. Put the key in the ignition, key recognised Switch ignition on, everything works as normal dash lights up all ignition on items work; dash, wipers, indicators, heater etc. etc. Turn the key to crank, engine starts and runs but nothing inside the vehicle works, just like the ignition is switched off. No dash, wipers, indicators, heater etc. I know it's my first post on the forum, I've always worked on and owned VAG cars, just trying to help a friend out. Would greatly appreciate any advise.
