Going to do waterpump and stat to be on safe side new cap ordered cars just done 1000miles to london and back think if was head gasket would have given up on motorway surly Head gasket falure at 66.000 on a merc is very unlikely i hope
If it's overheating it's not a good idea to keep driving it. If it's not overheating but it is the head gasket causing air to escape from the cylinder into the water system it would be a bad idea to keep driving it.
If the problem is blockage or poor water flow it would be a bad idea to keep driving it.
If more damage occurs from keeping driving it, please don't say this shouldn't happen to a Mercedes.
