Mercedes clase E 270 cdi w211 tears

[scarface]

I ? entry into the workshop this mercedes seghetta running at an engine speed of 1200-1500giri,just accelerate it, this problem disappears.
Diagnosis there is not any error, the egr valve ? ok,ducts, suction ok ,cutting is performed by a little,prex diesel ok,cutting to the automatic transmission did not know pi? that check and make sure.
And someone with this problem for the case or do you have any advice???

[explode82]

in the first place chiudigli the egr electronic piastrandola and give it a try and see if it clears the fault, if it does not disappear are definitely the injectors dirty or staratti,a little something you should notice it by seeing the correction of the fuel injection diagnosis

[scarface]

l egr l I closed electronically,the plate is not you can? mount like ? composed l egr.for safety I pulled the plug, dell egr but the problem ec.
The injectors from the time of diagnosis are not bad not wish bad.and then the defect does ache if you do not push the l throttle.
if you are down with a gear engaged, the machine strattona the same.

[sergiot]

you probably have the egr valve is stuck open. electronic controls can? do not respond

[scarface]

If it were open, the machine would fall performance.
The valve ? was disassembled and control ? clean

[sergiot]

since the car has the automatic transmission, maybe you have some problem on the adjustment of the clutch.
not ? said that it is faulty , it may just be from regular.

[explode82]

I would check the particulate filter,probably there is too much exhaust back pressure and does not detect it,sometimes I ? happened

[scarface]

This is not the particulate filter

[bergut]

try to make the regeneration of the particulate filter

I did not understand if ? the engine that the f? rip or and the exchange....
I think more the latter...if you have changed the oil in the gearbox make sure that they put one with its specific MB236.12 or 236.14 fully synthetic...many are not aware of this peculiarity? and I put the common ATF III mineral that f? more damage than anything else...
mercedes and very demanding from the point of view of lubricants...

[blackwolf76]

I would check the hoses to the turbo, if anyone ? a little broken, you create the problem, also check the sensor of turns...

[sergiot]

I confirm that if the problem you have also downhill with the accelerator pedal released, then it can not? be a problem of the engine no? of the control unit. ? a problem of the gearbox - the clutch.

[carlo abarth]

quoto for the transmission oil change......my capitata on a a4 tore crazy!!

[peaKpower]

That I know should be the torque converter!

That I know should be the torque converter! but snatches cold or at a temperature

[scarface]

The problem c'? I also downhill with the accelerator pedal released.
I checked everything and I even made the l transmission oil change with proper equipment but the problem is not you ? attenuated by nothing,but by all the controls that I have made must be the torque converter went.

Tears always, cold temperature,cold is known to pi?.

[carlo abarth]

at this point you'll want to remove the exchange!!!or, better, a nice laundry currency exchange!!!!

[blackwolf76]

Me na time na passat it was making me become a fool... in the end it was a wheel sensor that would send a wrong signal, and he was sobbing into the engine due to ASR. Try to disable it and see if the ref?... ? a test as many that cost nothing.

[munro]

scarface...if the oil ? ok.. you can try to enter into communication with the module transmission egs with a scanner and with the car in motion to try to do a calibration of the converter.....
then this is done do the activations of the valve gear with the scanner....
if you are still after these transactions, the exchange is still not v?...try to clear all the parameters autoadattivi of the egs...

[scarface]

problem solved,replaced the converter to the machine ? perfect.
thanks to all for your help
