Jerky shift, when heating is on
Still got the w211 220cdi 2008, with now 455,000km
When the heating is on, it shifts jerky, and i hear grinding sounds, and i have problems to downshift, it feels like it is in to high gear,but when i turn off the heating, it downshift perfect, and no grinding sounds, and its not jerky.
I have no fault codes in the gearbox or the engine.only code i have is the auxilery heating, that shall heat up the cabin, when the car is cold.
I also have a grinding sound from the aircondition pump, when the car is cold, and when i turn of the heating, the sounds stop. Can it be related?
Hope someone can help me a little here, what can be wrong
