Tempomat not working after replacing ABS modul

Hello Guys !I replaced my old ABS/ESP module, which was defective, with another module that didn't have the same part number. That didn't work and I ended up with more error codes. Physically, the module had more pressure valves than the original.

So I bought another module with the exact same part number, and MAGIC, all the codes disappeared after I changed the VIN in Xentry. Everything went back to normal and is working fine, except for the cruise control (TEMPOMAT). When I activate it while driving, the light blinks and I can't set a speed.

I asked someone to check in Vediamo and the TEMPOMAT is confirmed to be activated.

So, we can't figure out a solution to this problem.

Do you have any ideas ? i was wondering if the previous ABS module was factory installed on a distronic /HOLD assist car or something that i haven't ? That might have just made things worse ?

My car W204 c250 cdi 2010

The manual says to update the software when replacing the esp. You mention changing the vin, not sure if that means updating the software.

yep that’s it. Update the VIN into the new abs modul, like flashing the new injector. If i don’t, the error codes would come back.

You copied the coding from the old to the new completely.

No, I'm referring to the full coding. You can also try coding online, but if your part number is different, it may not work as expected. It's probably better to have a manual in that case.

What is your vin #? I never heard Tempomat before and not finding that term in the manuals im looking thru. I would like to see what version of cruise control you have. I'm looking thru USA and CAN manuals so may not be the same for yours, im assuming Germany?

the last ABS modul replacement has been done with exactly the same part number.

The official coding when you perform this operation is to update the VIN of the car. I also did all the « calibration » through Xentry.

My VIN : WDD2040031A357850

You might live IN USA ? Tempomat is the Mercedes name for cruise control.

The car was sold in France but built in Germany factory.
