COOLANT STOP ENGINE WARNING ON MERCEDES SLK 350 WHAT DOES THAT INDICATE

SOURCE: Mercedes SLK230 overfilling oil warning

5.6 liters here in the UK, could be a faulty sensor but try the oil first, easy enough to drain, jack up the rear passenger side so it gets all the oil out when draining.

SOURCE: Low coolant warning light stays on.

Bad coolant level sensor in the tank. Look around the bottom of the reservoir and find a plug connection, unplug it and see if the light goes out. I think the tank has to be replaced dont think you get the sensor out. You could try by take the tank off and see if it will come out of tank but I dont think it will.

Testimonial: "Thanks for the prompt reply. I will try the fix and, hopefully, solve the problem. Thanks again!"
