My mum has a ml430 that has been terribly neglected as such many problems have arisen. I would like to rectify some of these myself before I going paying Merc too.
Would like to know if any of you guys have similar problems and how you managed to rectify them.

1. Passenger window wont go up ( suspect switch ) Do i replace all of the switches or just the faulty one ?
2. Faulty airflow sensor, I was wondering if these are interchangeable with any other models
3. The last problem is that it fails to drop into low range, and the low range light flashes upon start-upi have no idea what this could possibly be
Any help would be greatly appreciated
Cheers

 

we have many case of this and the switch really needs to change.

yes. for as long as newer engines.

does it flashes 4 times within 2 seconds? check the operating manual for the correct sequence. you never met the prerequisites required.

if not, then the actuator motor or the control module got problem.
