Yes I have cruise control. The limp mode can start at any speed, often after just idling at a traffic light, or as I described, when overtaking at high revs.

Today I was lucky, driving 650 km nonstop in 28°C with no problems, but if I go out and start the car now after an hours rest it will most likely be in limp mode again...

To find out if the cruise control is a part of this, can I remove a fuse or what?

Edit: I did just that, restarted the car, it was in limp mode now, removed the fuse, no success...

We're still working on this car.

Agreeing with AMG, the "throttle surging" is probably actually the "cutoff" that we experience when attempting to accelerate. It feels like throttle surging when the power comes on and off rapidly. The limp-mode cuts power at 1500 rpm and then allows power again at about 1200, so, with your foot on the gas, it bucks around on and off and feels like surging.

We've done a lot of other research. We're thinking it's the Throttle actuator and the throttle actuator wiring harness. Harness is ordered from Germany (about $100)

We're going to send the unit to Beckman. They will test the Actuator for $80... which they will apply to rebuild cost if it's bad. (rebuild is about $1000 compared to a new MB unit at $2000+)

Incidently, mine occurred several times on 90 degree days, but happened most recently when it was only 75 outside. Raised the hood for 5 minutes, and it started right up again -- no problem.

Thanks for the update. You may be on the right track, hope youŽll find the exact problem since it must be just a minor thing in reality. Although it can be expensive nevertheless!

I gave up and bought myself a G500 and will take care of the CE later...

Please continue to post on your progress!

Considering you're going to send your throttle body out for check up and maybe reman, you might want to check 1 maybe 2 vacuum hoses.

One is about 1" long and connects the two parts of the flap housing.
When you remove the plastic intake to the throttle body you'll see this pik

http://www.peachparts.com/shopforum/attachments/tech-help/32996d1146490401-94-e320-pin-14-code-2-%3D-big-%243-600-need-suggestions-please-flap-pik.jpg

The flap housing is to the right. 4 bolts (2 under the plastic caps and 2 more further to the right.) Wiggle and the flap assembly will come off.

I'm a little vague on the following, because I was so excited to instal my remaned throttle body. ... I think there is another hose that comes off the (lower rear passenger side) of the throttle body (sorry I don't remember where it goes).

Obviously, if either hose is dried out or cracked, a bad vacuum could affect the performance.

PS I also had a reman done by 4Mercedes.com.
PPS Don't forget to disconnect the 3" link (ball on each end) from the throttle body and yes, the throttle body does come out between the 3 and 4 intake tubes, but it takes a bit of twisting.

E320 if FIXED!!!

Well, I am finally enjoying my "new" E320. A 94 with 24,000 original miles was giving me fits with it's surging and "limp" mode.

Did a complete wiring harness... which the car absolutely needed, but unfortunately that repair did NOT fix the problem I was having.

Anyway, the bottom-line is that I did a lot of studying. My mechanic talked to a lot of other shops that work on older cars like these, and ended up talking with a couple of real "experts" (!) Anyway, everyone's first guess was that the car needed a throttle actuator rebuild which we ended up doing.

Sent it out to Beckman Technologies and for right around $1100, they sent us a rebuilt unit (compare to $2000+ for a new MB part.) As you know, other guys rebuild them for about $500, but Beckman has the reputation for doing the best and most complete rebuild. One shop in Florida told my mechanic that he has 55 gallon drums in the back of his shop FILLED with throttle actuators from E320's and he has a pile of wiring harnesses 10 feet tall behind the shop. He said this is the problem 99% of the time.

Incidentally, my guy cut a slit in the wiring harness that comes off the throttle actuator and opened it up just for grins. He couldn't believe the condition of those wires! He told me they were all cracked and split exposing bare wire. There were black carbon-like deposits inside and it looked like it was caused by possible sparking, arching and so on. I was tempted to do a manual wire replacement job... one by one, but decided that I just wanted the problem to be over so we did the rebuild. (all this on a perfect car with an engine compartment you could eat off of) Amazing... the deterioration of the wiring...

Hope this helps with others struggling. It was a serious pain in the A**, but the car is a perfect specimen and a joy to drive. Between the harness, the Throttle Actuator, OVP Relay and a few other things we did, it cost me about $3000 to get the car right, with only 24,000 ,iles, I'm hoping to get many years out of this car.
