Took off the fender liner to see what I could see. Several issues. https://drive.google.com/drive/folders/1n5YVWGEa4IiffdThAgveyVzRIn4yQnie?usp=drive_link
Looks like the main line from the compressor to the nearby manifold has popped out of its fitting. Also note the intake hose and air filter lying in the pan under the compressor. The open end of the intake hose should fit in the little round recess I'm pointing to in the second photo? Don't see any other clip or likely place for it. And the other plastic line should connect to the pump where indicated in the third photo? I'll order a new intake hose and filter, but if the pump has been sucking unfiltered air for a while, I presume it might have some excess wear. Might replace it proactively if the "5503 Recovery time during filling central reservoir is too long" code persists? _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
