2004 CLK 270 cdi "coolant visit workshop"

[reeeevsy]

Hi all,

Just wondering if anyone knows how to stop the "coolant visit workshop" message displaying on the dash computer, I've had the car connected to the diagnostics and no faults show, the coolant level is correct and running temperature doesn't go over 80, any advice or suggestions would be apprecited.

When you had it connected to a diagnostic machine was it connected to a mercedes star machine as some generic fault code readers dont always pick up all fault codes.

Sensor itself may be gone (proper diagnostic should give actual reading), and washer bottle sensor is wired to the coolant sensor so check that too.

Change thermostat, temp should go over 80 (depending whats the temp grade of the stat).

I'd read through my last post here

before I spent any more money, I know its a different car but system will be very similar, expansion tanks from EuroCarParts are cheap as chips so could be worth a try then I would say check fuses (including for hidden ones) , good luck with the fix.

Thank you for the advice..

The diagnostic was only a generic code reader, I will check the parts that have been advised and give an update..
Thanks again all..
