Mercedes E Klasse Diesel Defrost Flap Issue

Hmm, sounds familiar. I had a similar issue with my E Klasse, although it was manifesting with inconsistent air circulation. Was the climate control behaving erratically? Did you check the dashboard panel for any unusual noises when adjusting the air distribution?

Inconsistent air circulation? Are the noises from the dashboard panel particularly noticeable? I am trying to pinpoint the exact location.

Yes, the inconsistent air circulation was key. Regarding the dashboard panel noise, it was a faint clicking, almost like something was obstructed. If the error code points to the defrost flap and the price quoted is reasonable, it might be worth having a workshop investigate before further issues arise. Is peace of mind not worth it?

Understood. Thank you for confirming the clicking noise correlation. I will proceed with workshop investigation as you suggested and advise when resolved. The issue was indeed a defective connection to the defrost flap actuator, as initially suspected. Repair completed.
