E320 2004: Cool inside and noisy engine!
I have little problems with my beauty (MB E320 2004).
Suddenly it started to blow only cold air into cabin, even though I put A/C off! Also engine is much noisier than before. At low engine speeds it shakes a bit and feels unconfortable to drive, especially when climbing up steep hills. Fuel consumption has also increased, in terms of miles per gallon the change has been from 16.8 mpg to 12.4 mpg in a normal city driving.
I unconnected the AC compressor, but I couldn't get very warm air anyway, and the noise was still there.
Any good advices where is the problem?
