I have a used 1995 S500 starmark with 30K miles. Major service is done. Recently while cruising the engine cut off and car stalled. Happened four times. Serious driving hazard. Dealer checked on computer and found no fault codes. However happened again with dealer foreman in car. Is this a known problem with S500?
For I had a similar problem with 1992 500SEL. Anybody have similar problem on this engine? or what causes it?
This car has been trouble. Had bad exhaust smell, to rectify this, Dealer has changed Catalytic converter-Air flow sensor-One fuel injector-O2 sensor-Remaining 7 fuel injectors for Smell problem. Hopefully smell is gone now. It has also new -distributor cap and engine timing cover.
Are these normal problems on S-500 class cars or is this a Lemon?
Engine cutoff is a new problem after all above parts were changed.

Have a '94 S500 cpe (below) and as far as I know, that's not typical for these cars.

So it looks like many parts have been replaced. Have these parts been replaced since the LAST cut-out? About the only thing you didn't mention is the "coils". That would cause that kind of problem and may not store a code.

PS: The ignition switch will cut the primary to the coils and result in the same cut-out. Also the Ignition Control module.

If your interested in DTCs, check my page (red house) for where YOU could get involved and probably fix it! There could be codes in the other modules, other than the Diag module.

Thank you JimF.
All the parts mentioned, were changed in last two months.
Cut out problem occured two days back. Car is again with the dealer, for further diagnostics. I think its the ignition module, had same problem on my 1992 500SEL, chan ged the ignition module sensor, but the problem persisted. Finally traded that for this 95 S500.

Did this happen after all of this work? If so, I would have the tech make sure that all of the connections are really good.

Also, I have seen the ignition switches do weird things.

Hi Benzmac,

Thanks for your reply.
All the parts mentioned in original post were changed earlier (January to April 2001 )to solve the problem of EXHAUST GAS smelling like rotten egg / sulphur.

The engine cutoff is something new started in this month of MAY.

Got the car back today. They said it was due to poor GROUNDING. Cleaned the contacts etc.....

Thanks all for your replies.

Wonder what the ground point was? Was it W16? That's the ground point for the car's ECUs.
