E350 2010 w212. All dashboard lights turn on while driving, now car wont start
Today while i was driving all the warning lights in the dashboard turned on, so i stopped by the side of the road and turned my engine off. After that i have not been able to start my car. I was thinking it must be that my battery has died so i tried to jump start it whit the help of some jumper cables and my friends toyota but nothing....
Anyone ever has this happen, all the dashboard lighting up while driving? I will continue trying to find the fix tomorow and would appreciate any advice on where to start and what to look for.




Did you notice any other suspicious lights BEFORE the sudden xmas tree light show?
Got gaz ?
Did a baterry test and that is all good. Kind of confused as i dont know that much about cars but looks like im getting a new starter first

Also if my starter would be faulty should i not see that in the diagnostics report? I only get alternatior errors but as i uderstand that dose not effect the start of my car.
Alos got eroors 16F600 and 16F700 but diagnostics guy says these can be ignored for some reason.
Dose all this makes any sense at all?

- ALTERNATOR faults
- bad starter
- good battery
Can any of this cause your car to stop? Yes, the alternator not charging will bring low voltage warnings before car runs out of power and quit. At that point not enough charge to crank starter but enough for dashboard lights.
I really don't see how a bad starter would cause the car to quit while driving...
The whole point of diagnosing your problem is to not change good parts for no reason.

However, I recall that a 2010 W212 still uses pyrofuse at F32 prefuse box, like this PDF attachment by Chief K at this post :

If that pyrofuse blow, starter is lost and SRS warning will probably be triggered...hence christmas tree at the instrument cluster.
Without 2009-2013 W212 wiring diagram, I can't yet confirm if the non facelift W212 pyrofuse serves both starter and alternator or not.
If you see the PDF, it shows no dedicated big fuse for alternator... so I suspect a tag along to pyrofuse or has no fuse.
For facelift model, pyrofuse is at battery positive post and is a dedicated wire to starter motor. So pyrofuse only serves starter motor.
Alternator has its own dedicated wire and fuse at F32 front prefuse box, terminal MR8.

Yes the car still has power. Everything seems to be working fine.

Hey man thx for the tip!
Im going to a friends garage on monday and will lift the car up there and go over everything we can see whitout taking it too much apart.
I do belive that an electricl problem would make the most sense so this sounds like a very possible fault!

I did chage my Ignition relay cuz i saw it was the already changed before so thought that might be it....it wasnt.
Will go over all the fuses just in case and try to find this box if i have one.
Thx for the advice i really appreciate it

If indeed your engine jammed up, it is a horror story...but if during the warning light christmas tree you hear no funny sound, and engine was turned OFF by you and not suddenly died on its own,
I sure hope your engine is not jammed up.
