MERCEDES BENZ 190E 1.8 SLUDGE IN THE HEADER TANK

1994 All Other Makes All Other Models

I noticed when the coolant light came on and I checked the water levels in the header tank that there was a brown sludge in there. I took the tank off and flushed it out as well as the connecting pipes but it seems to have come back. There is no white residue around the oil filler and the oil seems fine I took it to a garage and they gave it the sniff test to check head gasket but told me the gasket seemed fine. On cold mornings the car is sluggish and judders with no acceleration and sometimes stalls in reverse. I would be very appreciative if someone could help.

Have the cooling system flushed. If the sludge is in any way interfering with the coolant sensor, then it might take care of the problem. The sensor cant read air that well, by being low on coolant it could be messing with it.

The system has been flushed and refilled but the sludge just keeps coming back
