My wife's 1992 300E just went through this same "SSS". It would stall in stop and go traffic as well as when she was taking a turn a little sharp at an intersection.
I replaced the Overload Protection Relay ($63) which is located behind the battery next to the computer module. It was a 5 minute repair and the problem is now remedied. The old one had water in it which was evidenced by condensation built up under the clear plastic double-fuse cover on same. This is a common problem. When/If you replace the module, put a bit of vaseline on the O-ring gasket for the double-fuse cover. Search the Parts icon on this website for a photo and ording information of this module.
It might also be:
Coil
Fuel Injectors
Wiring harness

But I'd begin with the least expensive and easiest remedy in your troubleshooting and go on from there.

Good luck. Ain't this fun? The Mercedes Benz dealer/service shop in Naples estimated $1400 to do this job for me. They said "wiring harness cracked and needs replacing". Bulls#$& !! There was nothing wrong with the harness. It is brand new and was replaced only 2 years ago. It is in perfect condition.
Watch out for scheisters.

do you still need a solution or proceedure to fix your problem? or has your problem been addressed?

Muhahahhaa that's exactly why someone sold me this car for cheap, they just think it's a 1400 repair that might not work but I got away with a perfectly healthy car for 75CAD worth of parts.

I was reading your post on your 300TE 1989, SSS, more than an adventure ... here's the link to Benz-LGB thread:

http://www.peachparts.com/shopforum/showthread.php?t=113327&highlight=Hall+Effect+Sensor

What a Saga!!! you track the problem from May 2002 up to what 2005 does it still ok now?? Or does it still suffer from the SSS??

As I mention on the beginning of this thread the goal here is to get as much info as we can from people like you who goes throught the SSS and find the solution.

With the symptoms and solution we have troubleshooting experience.

Reading your post I learned some difference between your Stalling cause by HES and the Stalling on the C220 1995 from Hk20000 cause by an OVP.

Here how I will check next time if the Stalling was cause by the Hall Effect Speed Sensor(HES) this is his real name in fact.
Reading my Shop manuel teach me that this sensor was a Vehicule Speed Signal and it is process by the control module.

-Symptoms:
- the engine stall on coasting and deceleration
- Abs light: Off
- Easy to restart after stalling
- The last one I learn it from you. You mention in one of your post.

"" On the way home I took the car to a deserted country road near where I live. I tested the car by accelerating hard (it accelerates like a rocket) and then coming to an abrupt stop. No stalling. ""(from your post #8)

By doing an abrupt stop do we by-pass the Hall Effect Speed Sensor??? It look right to me for your year and MB model.
Time will tell if this way of checking it will work with different model.

Thanks again

After the car began stalling (as described in my last post on that thread) again, I returned to Enrique.

It was at that point that we replaced the HES and (here it is where the supertitious part of me takes over) the car has been running fine ever since.

as an aside: I was so concerned with the stalling that we bought my daughter a Certified 2002 C320 sports wagon. What a wonderful wagon/car!

We kept the 300TE, which I drive on a regular basis. The W124 wagons are great cars.

Hope that the info on my thread helps you out!
