Thanks Uberwgn. Have NEVER known MBDOC to be wrong or misinformed in ANY information he provides so must believe he viewed this situation not as a "problem", but a complaint.

Mdisav - Your comment concerning bypassing the EGR ties into what MBDOC said long ago. Perhaps your bypass procedure is the "out of warranty" fix to the "complaint"?

My car, a 99 E300 Turbodiesel, has the exact symptom on decelleration. I have an additional feature which is a "miss" or intermittent rough idle only when the car is at operating temp. and only while in neutral or park with no elctrical load. Switch on the climate control, headlamps, seat heaters, and the car idles normally. Thus the techs have ruled out a bad IP as the source for the roughness. The car runs too well for this to be more than an annoyance, but clearly something is amiss. The rough idle is a relatively recent development that coincided with an alternator relacement, but the decelleration issue has been with me for at least 50,000 miles. So if you can live with it, it is probably not likely to hurt your car in the near or long term.

The EGR bypass will be tried as a fix--hope it works.

Steve

Since I last posted I have consulted my diesel engineer and Merc main dealer.
My diesel man liked the ECU article by Stu Ritter, as he now believes that there is a softwear glitch.

I took the article along and showed the Merc dealer and was surprised that he didn't freeze!
He made enqs and told me that the part no quoted for the ECU was not a part number they knew and was probably a US part number, not British.

I have done other enqs and was lead to believe that any part no that ended 05, was the subject of a recall. He checked recalls and there was not one for this part, neither had my car missed any recalls.

He said I could have a chassis matched exchange ECU! I really can't see how that would be any different to the one I have!. But suggested my car go on their diagnostic tester first. I may well just do that so that when it shows no fault I can say "what the hell is that then?"

I am going to run the car with headlights/aircon just to test Steves theory.

Is there anyone who can confirm that part numbers are different for USA and GB and that 05 denotes a recall, and confirm the part number given by Stu Ritter are correct, and even where I could lay my hands on one of those ECUs?

Thanks again, John.
