Frankly, it’s not a major issue, just inexplicable. At least, I can’t track it down but I feel sure it’s part and parcel of the original stalling problem.

To recap.

Basically, the car runs like a dream. Smooth, starts well and up to 30 mpg if driven gently.

It’s a 124 series, 300CE-24 with M104 engine, 1991. I’ve had it for 10 years and, from day one, it’s been a staller! Originally the stalling was provoked by brakes and turning at the same time, however, it was prone to stalling at the drop of a hat.

The following parts have neen replaced:

Fuel pumps
Fuel filter several times
Fuel accumulator
EHA or Guvernor
Idle Control Valve
Air filter numerous times
Over-voltage Protection Relay (twice!)
Camshaft position senser.

And probably other items I’ve forgotten.

This stalling seems now to be linked with nothing. An example:

I stopped the car and left the engine running. Removed wife’s case from boot and closed boot. I walked around to open driver’s door and, before I reached it, the engine stopped!!!

I restarted it immediately and without hesitation.

So, where do we look now?

The only other symptom is this (imagine the scenario):

Arrive home in Drive and bear to the right and stop. Move selector from Drive to Reverse. Reverse to parking position and select Park. Engine stops.

Solving this is more of an obsession than a necessity but it would be nice.

Any and all comments gratefully received.

The best to all.

the early M104s have problems with the coils.
and they are prohibitively expensive

Thanks for your reply.

The early 104s had 1 coil, assuming you refer to the ignition coil. I have another in stock but I never thought that was likely as the engine performs so well in most other areas.

Life's seldom simple! The parts catalogue shows the TWO possibilities shown in the attached PDF.

Item 5 is marked Sender unit TDC.

Item 22 is marked Sender init position EZL.

So far, I cannot locate either in the car but I haven't had time to remove air filter (for Item22) or go underneath for Item 5.

Curious and curiouser, isn't it?

Mine is an M104 3.0 engine in a 1991 300CE-24 so does it have both?

Maybe I'll have to go to the garage and look underneath.

I'm sure I'll get there in the end.

Thanks to all.
