NSX2NV

So I went to work this morning and everything is fine. Then I'm leaving and once I start the car I hear a slight whine. It then says electrical consumers are switched off. My heater isn't blowing hard at all, even at full and defrost. Then my radio says battery low and to start my engine or the system will turn off in 3 minutes. Then my Abs light starts to turn on and off. Then it stays on and the ESP says it malfunctioned. Then the screen turns red and say Brake Longer Stopping Distance, and Brake reduced braking effect. Then my Brake light turns on along with the SRS light. So every light is now on. I get to my stop and turn the car off and tried to start it again. It won't even crank now. Has anyone experienced this before? What is wrong and what needs to be done? Any help would be great!

Thanks Again Guys!

just guessing

battery or alternator.

does the car turn over when trying to start or does it do nothing when turning key

Maybe alternator went bad and drained the battery. If it cranked fine at first start and now it won't even crank ( or barely crank ) then I'm pretty sure it's the alternator.

Voltage Regulator?

It won't crank at all. The car will start when jump starting. Then will die a little after you disconnect. I'm 99% sure it's the alternator. I'm bringing her to Mercedes to get checked now..... anyone have any lube I can borrow

if u know how to use a volt meter you can see voltage to battery in trunk or i think dyno mode will tell you voltage.

its the alt, find a good indy, or your going to need that lube

AWOL

I had this exact, and I mean exact thing. Dealer replaced the alternator under warranty.

But 100% its the alt.

Good luck

Maybe just voltage reg. Good DIY. https://mbworld.org/forums/w211-amg/...lternator.html

I don't know man, I just went through this, replaced everything from batteries to voltage regulator, ended up being the alternator.

I did say maybe. Worth a try for a $41 DIY. I am guessing the alt is going to be $$$ at the dealer.

dosnt a new voltage reg come on the alt?

If not under warranty go with the 41 dollar part
