Hi,

New to this forum and was wondering if any of you guys could help.

I have just purchased an 05 C200 CDi Diesel and over the last couple of days a fault has arose.

When you turn on the ignition it reads Coolant Visit Workshop and the fans are staying on whilst ignition is on.

When it comes to cars I am quite clued up but obviosly it could be a sensor down I have checked the coolant level which is fine, top and bottom hoses are hot and I have changed the plug in sender unit on the header tank but this didn't help.

The dash says 1 Malfunction when I disconnect the sender on the header tank it says 2 Malfunctions so I presume it isn't that as the temp gauge is still working.

I am not too sure if it could be down to the tempreture sender on the front of the engine block ???? I have disconnected this and it doesn't register any further malfunctions.

Any Ideas before I have to go to the dreaded main dealer. The car is only out of warranty by 3 weeks.

I do work in a garage but the mechanics are pretty clueless when it comes to this sort of stuff as they dont work on many of these cars.

Cheers,
Martin

disconnect the fan plug, you might find it green in there and the pwm pins are no longer with you, new fan and wiring from the front sam!!

Just thinking the temp sensor was short circuit on the last one
