1999 w140 m104
 

I've been thru 4 starters since November 11.I been using
Advance Auto Parts starters made by world wide.The Manager says with any other car but mine,they are zero return.Sure its alifetime warrenty,but its 101 degrees and I'm tired of changing starters.
I had bought a Bocsh and they sent a backwards starter.So now I'm thinking Denso.
Help. Nathan

here's one thought buy a starter for a german s 320 cdi.Nope they are ass backwards too. made for passenger side,my starter is on drivers side

This starter is the same for all m104 engines c280,e320,s320s ect..
each time the solenoids go.

Sat 2 days now it starts.Had a pause before starting

she works now could be battery charged up?it cooler this morning was over a 103 last 3 days.Do these cars have a ignition module?:)

Answer
 

NO, there is no starter module.

My best guess would be:
* a bad ground, body to engine/transmission.
* a failing NSS = Neutral Safety Switch on the transmission.
* a failing ignition switch.
