Hi all, new to forum. I have a 2002 S430 in lovely condition, 205000 kms. Had warnings, airmatic, abs, bas esp coolant come up on dashboard, upon checking found alternator faulty. Fitted new alternator, cleared codes with Snap On tool. Drove about 45 kms most of those codes reappeared plus display defective. Electric windows also stopped working. Any suggestions.

Was it in the rain before this happened ? SAM probably got wet

Thanks for your answer tusabes, no it wasn’t raining. Where is Sam located? I’m still learning this vehicle, I’m an ex MB mechanic back in the 70’s until early 90’s, not quite tuned to this tech!

I don't know where all of them are located, but one SAM in the 2003 S500 is located attached to the underside of the fuse block on the right side of the engine compartment. There's a YouTube video on how to get it out and replace it but I don' t have the link.
