Mercedes CDI Lack of Power solved by MB SD Connect C4

Diesels in the workshop often has common problem that lack of power or some people describe it as the kick down not working.


Firstly do some basic checks like oil levels, fuses etc.


Step 1: listen for any escaping air under pressure when you are driving at full load. If this is the case you will probably have a boost pressure leak from somewhere. The common areas are: Intercooler, rubber boost pipes and the inlet manifold itself. If you suspect a boost leak then listen at the front of the engine and see if you can hear where it is coming from while a friend gives the engine some RPM.


Step 2: get it plugged into a Star diagnosis I.E MB SD Connect C4 and get the codes read. This is the most important thing to do before buying ANY parts. Assume there are many people have the same problem as what they have read and replace the same parts and be confused why it hasn’t fixed it. Get it plugged in. It will save you much money in the long run I promise you.


The most common item to fail and nearly always brings up a code is the infamous Air Mass Sensor or MAF (mass air flow). It is always worth doing a manual check with the live data just to be sure that is the cause.


A common fault code that comes up is a fault with the boost pressure sensor. It will say either under boosting (lack of turbo pressure) or over boosting (too much turbo pressure). So many people will replace this sensor for this fault when the sensor will be working perfectly.


Checking the sensor values with a Star diagnosis helps determine this. Under boost: Check boost pipes for leakage. Over boost: has it been mapped badly? Is the turbo actuator or vanes sticking?


We see quite a few inlet ports shut off motors failing too. The V6 diesel, 220CDI and the 270CDI all suffer. This will give you lack of power when they fail and an engine light will come on in the case of a V6 CDI. A check on a Star diagnosis will bring up codes for this.

I hope this helps.

Working solution to MB SD Connect C4 unlock dump

This is a dump read out from PIC16LF88 chip of my own MB SD Connect C4 device (4-5 years old). It’s 100% working.

Mbstarshop engineer know it exactly because I’ve succesfully unlocked 3 units for last 2 days using it. Each one works fine.

You don’t need to buy a new one PIC16FL88. You just have to program chip from your own device.

After that when you run your SDconnect you will probably see that serial number, OS version of your device are changed into zeroes “0000”.
Don’t worry. Just change your C4 to factory state using buttons near by LCD (no need to explain “How to…” because it’s quite clear). After rebooting you’ll see actual SN, OS version and so on.

Also you can change serial number of your device. 24c02 contains it. After changing number just run “factory settings” function…other way it will not change. After reboot you’ll probably see (on lcd of your device) your SN looks like “the number you’ve programmed into chip +1″… I mean 10001 inspite of 10000 for example and so on, but in SDNC tool kit you’ll see the real SN (10000), and after succesfull reconfiguring your device you’ll see the right number on LCD of your MB SD C4.

I was using cheap ssop28 (0.65mm step) adapter and Pickit3 programmer to read/write PIC16lf88. This scheme made for Pickit3 OEM socket(ICSP).

Also I’ve got dumps of both flashes 29f016 and PIC18lf8680 if somebody need it.

Somebody asked me if I have dumps of both flash memories 29f016. Finally I’ve found them. In the picture below you can see marks A & B made with pencil and dumps in archive are also named according to signs in the picture.
One of archives (probably – device1) contains dumps from device which didn’t support command CE_flash_loeschen and the other one ( it seems device2) contains dums from working SDConnect.

I read them both using Triton 5.7 programmer with hand-made adapter for 8-bit flash memories (29XXXX).

If you try to read-write them using TL866/wizardprog/willem…then don’t waste your time. These programmers won’t dothis job. But it was few years ago, so probably something changed.

How to configure MB SD Connect 4 RS232 convert cable

In some cases, Mercedes Benz MB SD Connect Compact 4 diagnostic system owners will come across “Initialization of the multiplexer has failed” when installing the Star diagnosis software.

And the most frequently reason to the problem is because the wrong/incorrect computer configuration.

If you did not get the Dell D630 laptop with MB SD C4 and use your own laptop, make sure your laptop has COM port and strictly follow the software installation video instruction.

If your laptop is not compatible with com port, you need to buy additional Z-TEK USB 1.1 to RS232 convert cable or PCMCIA PC COM port convert card. Because necessary com port setting is required during the software installation procedure.

Z-TEK USB 1.1 to RS232 convert cable is the cheaper choice than PCMCIA PC card. Then how to configure RS232 convert cable for Star diagnosis multiplexer?

1. First do not start the Virtual machine

2. Set the Z-TEK USB 1.1 to RS232 convert cable COM Port to “com 1”

3. Start the Virtual machine and remain the com port setting (do not set com port this time)

Or simply follow this way:

1. Do not run Star diagnostic software

2. Turn on the computer

3. Install Z-TEK USB 1.1 to RS232 convert diagnostic cable adapter driver and set com port to OCM1

4. Run Virtual machine and do not set com port again
