I did a Trans fluid and filter change on my 06 E320 CDI . Now the engine cuts out above 2400 RPM . It will do this at all times even in neutral . All the dash lights flash and the engine goes on and off rapidly . Please help !

It sounds like the ECU isn't getting a speed-signal. Are you SURE you didn't yank out any connector(s) on the side of the tranny? The I6 CDI also has a crankshaft-position-sensor on the drivers' side of the engine bell housing in front of the tranny. I suggest getting back under the car to check things out thouroughly!

I have rechecked everything and there are no leaks or pulled out wires . My local Independent scanned it and found no codes or problems . The Indy said the rail pressure spikes when the engine cuts out . He charged me nothing and advised me to bring it to the dealer . It is there now for 3 days ( since 7/14 ) and they are not having much success . The dealer has a $125 fee to diagnose the problem and has turned up nothing yet . All advice is welcome and I will post the results when this nightmare is over .

7/19/11 ... Stealer called today for a little grease and insert session . MB in Germany says replace engine ECM . Problem has nothing to do with Trans fluid change . One year warranty on parts + Labor on ECM . Price is $1550 + labor total $1861 . When I asked what if this doesn't fix it what happens , Stealer replied " That's what MB says to do and if it doesn't fix in more diagnostic work will be needed " . The way I see that is MB is taking a guess on my dime , I hope they are right . I should know on 7/22 and will update .

No matter what happens , it is disgraceful that a 2006 car needs a new ECM !

I agree. I would ask a few questions as to why it has supposedly failed.

Can it be repaired? Try http://www.autoecu.com/ & other googled sites.

Can one be taken from elsewhere & put in your car to check whether yours is at fault?

Good luck & let us know how you go.

These guy must be charging some unbelievable labor rate. Cannot imagine the labor cost. Switch out the ECU and Flash? I would ask them what the hell they are doing for $1861 dollars.

My car has returned at last on 7/22 from the Dealer . The ECM has fixed the problem . I have the old ECM which is a Bosch part # A 648 150 42 79 it was in a MB box with the same part # . Labor was $248 / parts 1563 / fuel 20 ( they put over 109 miles on the car ) / 29 misc ( special MB grease charge to ease the pain ) / Tax 112 .
The only thing that I can say I did during the Trans oil change that might have caused this was playing the radio for 2 hours with the key on . The car was absolutely fine prior to the fluid change . It came off the ramps for a test drive and the problem was immediately there . All mechanics have said it was a coincidence , but I find that hard to believe . Please learn from my mistakes !

On a more positive note , The Mobil 1 Synthetic ATF which states on the bottle it meets MB spec 236.1 / 236.2 / 236.5 / 236.6 / 236.7 / and 236.9 has made a great improvement in the trans shifting . On the Mobil web site they won't state this and after calling a tech at Mobil they did finally admit that it would work OK in my MB . I have talked to my Mobil rep as we by 55 gallon drums of there products and he stated that MB is not in the oil business and specs out all there fluids . MB has a glut of this fluid at $22 a qt and wants to get rid of it and Mobil has taken the spec off the label on all new packaging . The tech I talked to on the phone said it was older packaging that I had and the newer bottles have no mention of the MB spec . This is MB trying to do its typical nonsense in my opinion .

Thanks for all your input . Best wishes

Please to hear that you are back on the road. Scares the hell out of me as I plan to do a flush too!!
