Thanks, it has a new radiator and thermostat. It runs generally at 82, Rising to 90 -95 in London traffic, can be ok, no overflow. Long runs are ok, it's when you either stop or get in traffic, then temp rises to the 95, but not always, then with the engine off after getting petrol or...

No, It was the one I kept after replacing it with a new mercedes bought one, it was ok But the time, but noticed the edge of the rubber starting to split.

cylinder leak test Those in the know tell me a cylinder leak test is my next option. I still can't make sense of this problem, the water only escapes through the overflow when I stop. Happened again tonight, did 18 mile each way trip, first half, all ok, second half after some London traffic...

I think your right, deep down i think it's the gasket. I also noticed a while back the idle is not as smooth as it used to be, you can see the bonnet vibrate by the windscreen sometimes, yet more evidence i guess. I'll get local lad to do compression test in the week

stumped now ! Friday afternoon the car continued to lose water from the overflow after a short local trip. To 're cap, head gasket was done time ago, and the test using a green liquid performed by my local mercedes independent was to prove negative. I changed the filler cap, no difference...

I have the viscous fan on the engine, and as you rightly pointed, a thermostatic (which is a bit noisy) for the air con mounted on the radiator.

update Managed to get to a friend's garage today, who specialises in mercedes, and has done plenty of work help me in past, and it was them that did my head gasket time ago. Anyway, they gave my car what was called, I think, a sniffer test, albeit the test was a green liquid in a special...

Forgot to say, auxiliary pump does have a 12v supply, it's the switching of the earth that seems not to work

Update. Covered 100 round trip last Wednesday, no problems with temperature, steady 85c, no water loss. Next day, battery flat ! Water temperature good all week, no loss until today, when evident from overflow. Seems the problem relates to stop start short runs, which today was. I followed...

Short trip today, 10 miles each way, no problems with temperature during trip. Stopped off at local shop for five minutes to get a snack before returning to my workshop, and could see water leaking from the overflow pipe behind front wheel. Returned to workshops, less than half a mile, and line...

I shall be somewhat upset if it does turn out to be the head gasket. Cost over a grand last time as I had the valves and seats renewed, radiator pressure tested and cleaned. Even bought genuine mercedes gaskets to be sure all was as it should be. Garage was also a mercedes specialists, the owner...

Having monitored the water temperature and any coolant loss over the last few weeks, it has been interesting. On two occasions, and after a short run, then a second short run, there has been water cooling out of the over flow behind the front wheel, could be due to over filling on my part. Also...

Forgot to add, sounds like a relay connects behind air con buttons when air con buttons are pressed ?

Tested duo valve connectors using a wire with a bulb soldered the other end. Lights comes on Only when the air con buttons are pressed and I noted the top button for defrost only works if part pressed, push it fully home and bulb goes out, so faulty top button. After this test, I then...

I think your right, No problems with air con overall, just the push button switch mounting fixing doesn't look as professional as one would expect for a mercedes. The button assembly should ideally be a snap fit to the plastic base plate, but my one is gooed in position and the cover for the...
