Hi,

E93 with N43 and MSD80.2, manual transmission, FA in attachment. Rougt running on iddle. No reaction on accelerator pedal at all or die when I touch pedal.

I notice, that throttle dont move at all but also no error codes in DME.
- check wires from throttle to DME - OK
- check voltage supply for hall sensors - 5V OK
- disasembly throttle and check motor - run in both direction without problem OK
- check voltage reading from both sensors in accelerator pedal - OK

Check hall sensors reading in INPA. There are two hall sensors. Reading of second one should be like V2=5V - V1. In my case it's true only for throttle possition >45 degress. From 0 to 45 degress value of first sensor move, but second show stable 2,69V. Connect another throttle but same situation. And like I say before, there was no error in DME.

DME's software was 7635282. Check kmm_ATSH and this software was for WK71 code without 843 (power reduction). So everyting seems to be OK. I backup it and flash and code to 8687860 based on HIS file. 

After flash:
- errors from throttle body adaptation show in DME
- reading of second hall sensor is same as before.
- engine worki same as before.
- car don't want to start even when i press clutch pedal - it just turn ignition off. It start only after I code out "start witch clutch pedal" from CAS.
- need to hold start/stop button for a while to start engine

So, I think somebody before me remove throttle DLC from DME and problem is in DME. I just order secong hand MSD81.2 and will try it.

But maybe problem is in software? 
- Could somebody check, if 8687860 is correct sw version for this car. I dont see any different software in  kmm_ATSH and kmm_SG for 205 option and without.
- Anybody have clue why problem with clutch pedal and start/stop button after flash occure?

Thank you and all good in New Year to all

Connect ISTA and make a plan to check for throttle error, if adaptation fails then DME is to blame.

For me, if the beam is working, DME is a problem

Can be ecu problem, but did you reset adaptions after flash and allow car to go sleep? These engines can run crazy if you just reset adaptions and start it straight way without allowing vehicle go to sleep.

Hi, 
problem solved by replaceing dme.

Change dme, program to correct software, code. Adaptation was reset. Now everything OK.

Thank you
