unwanted heating
I have the following problem
After driving, parking and starting again warm air is coming out of air nozzles and temperature is coming down very slowly.
Does anybody know this problem or the reason or a solution

The issue is the lack of a simple valve to route the engine heat from Bank2 away from inside the cabin.
This issue is somewhat controversial for people with a normal bypass valve. They can't believe MB omitted a control valve.
A/C cooling is poor instead of frigid.

you are not alone Frenek.Its just you can sense it better than me because your ambient temp is probably 20C where me at 30 ish Celcius and when outdoor parking car interior get sun baked to 55-60C.
So your car is the same engine as mine I assume, being a coupe E400 with M276 3.0 Turbo and not hybrid 3.5 NA right ?

Yes some of us are very much aware of this random issue. On some VINs the cabin heater has no control valve to keep it from always being fully heated over 200°F. I know how this feels iin summer

good: I do not spent more time and money looking for solutions
bad: I have to live with it......

Ohhh, you are the rare 3.5 Turbo one. Sweet
If you one day use mercedes WIS and EPC, my engine alone is already kind of little nightmare, your much rarer engine will be a higher level of nightmare due to mixed up between M276.9xx and ours M276.8xx in some wiring
and parts. My engine is low quantity, yours is even MORE lower quantity for W212/C207 or A207 generation.
But hopefully under C207/A207 chassis its not as difficult as my engine under W212 chassis.
Do me a favor please please.... photos of your engine with the plastic cover removed ........please. I never seen 3.5 turbo one . Thank u
