On my 2010 E550 it says my blind spot is inoperative. It also says my key batteries are dead so it won't push to start. I tried that on both keys. Everything else seems to be working fine. I did some searching around and nothing seems to be the main issue, except maybe being dirty. Any body have any ideas?

Yep, find someone with factory or equal diagnostic software or take the plates off the car!!

Seen lots of lane assist module failure on the GL,Glk and ML in Canada they get corrosion .

How would I check for that?

konigstiger

BSA control unit (front passenger footwell), radar sensors (located in rear bumper), or lamp indicators in outside mirror may be malfunctioning. For definitive diagnose, have dealer or independent with SDS (MB diagnostic equipment) check for fault codes. No codes, they may be able to correct with recalibration and/or software update (if available).

I think I will be taking it in this weekend to get looked at. So I will tell them to check these areas.

If they have the appropriate diagnostics and experience---all you have to tell them or whatever is I am having trouble with the lane assist bla bla----if they need help in locating any modules----run away!!

My only concern is because I bought the car from a BMW dealer so I don't know if they have the right system or not.

Plutoe

That is a concern, they don't have the MB tools and the experience and will no doubt shop the car to an MB dealer!!

Ask for a copy of the quick test and watch the expression on their faces!!

So I have noticed that when I start the car the orange indicators on the side mirrors come on the turn off. Would that give any indicator of what it could be?

Well this is what it turned out to be.

I hope you can repair the terminal end on the $1200 part.

jylee

Can you repaire the connector, the mirror is over $1200.
