(Solved) Mercedes W203 EDC16C2 ECU problem not crank and not read on BDM

This post begins with Mercedes W203 EDC16C2 ECU problem that MPC556LF8MZP40 wont crank and ecu not possible to read on BDM, and finally solve the problem. To know how to solve this problem, go on reading.


Car model and year:

MERCEDES W203 EDC16C2 ecu 0281012451 A6461504091.




Ecu has problem with MPC556LF8MZP40.

It wont cranck untill you heat mpc little bit. Around 20C.

Also ecu is not possible to read on BDM. It cant recognize it.


What tool used to test?

Tested with FGTech Galletto and BDM100 ECU programmer


Detailed problem description:

So I found DUMPS on forum readed with DIMSPORT.

Because i am not sure that dumps are ok, i have to program them in to another same cu from W211 so i can test it on mercedes w203.

After programming W211 ecu with BDM100 in dimsport software i use external eeprom from W203 ecu and program it in w211 ecu.

I test it on car and everything went fine. Car start and no fault (checked with DAS).

After testing i use GALETTO and read w211 ecu and save files. So i have files that work.

Then i start to searcH for used MPC556LF8MZP40, and i found it in FORD FOCUS EDC16 working ECU.

I resolder it from ford ecu and re-ball it and solder it on mercedes w203 ecu. I connect it with GALETTO and finally i can connect it. 

When i look better i saw that eeprom PROGRAMM and READ options are disable.

So i was thinking ok that was wrong dump inside MPC and i start with programming MPC. After programming MPC i restart the ecu and same problem.

OK i have to program also external FLASH and MPC. Maybe that could be the problem.

After programming MPC and flash i have still the same situation. Not possible to read and program external EEPROM.


Finally, Solved!!!

Problem was bad mpc. When i heat it littlebit i get access to the eeprom. i replace new mpc and now cor run smootlhy.

Solution for Toyota Techstream not displaying AHC pressure values

My personal issue goes as follows:

I am the original owner of a 2006 LC with AHC. I have 168K miles on the truck and it has been a true workhorse. I recently purchased a cheap MINI VCI on to troubleshoot an issue on my Tundra and thought I'd poke around a bit on the LC. Specifically I wanted to look at the AHC pressure values. Based on what I'm reading I'm probably way overdue for rear springs and torsion bar adjustment. 


The cable seems to work with Techstream V10.10.018 on all of my vehicles but it isn't reading the AHC pressure values on the LC. I saw in an old thread that I needed to pick LX470 when connecting to the vehicle otherwise I get a "selected system is not available" message. 


I also read that on a cable check it was necessary to read from pin 7 and as you can see in the attached image when connected to the LC pin 7 is red. When connected to another vehicle with the same cable pin 7 is green but 6 & 14 are red. I don't know what to think about any of that.


Does anyone have any thoughts as to what may be the issue?

I'm getting ready to do an AHC lift with some coil spring spacers, adjustment on the sensors, and rear shock extenders. I get all the parts installed but I have the techstream cable and CD ready to go.
