No longer a Benz...
My Coupe daily snail uses water, its done 56k miles and freshly serviced 2 months ago.... no visible leaks and no oil in water.

I can regularly sit in London traffic, recently on Friday for 2 hours slow traffic... and i can smell coolant... the gauge never rises and i have only had the "add coolant" message on the dash once as i'm over cautious and always check the water.

I've read on here and the web that the expansion cap could be the culprit, so I have one coming next week... anything else to look at?
 
Have the cooling system pressure tested if it continues to lose coolant.

My expansion tank had blistered. Used to need top up every so often. Terry changed the expansion tank and all was good :thumb:
