The dealer now states they contacted Mercedes Factory Rep and he said "Normal Hose collapse due to fluid contraction when cold"
"If head gasket failed the hose would expand" and that a temp of 100 celsius is normal.
My question is how does fluid "contract"
and how many of you have cars that run at a 100?
Engine is clattering and milage has been droping steady.
the say to change to Hess Fuel as that theres nothing wrong with engine.
I have this in writing from dealer.
