Yep, it can be done easily.
Mercedes basically gives you a brand new ECU, which they program to your car with their MB Star tool. This is nice, but this costs WAY too much money!
But you can do it loads cheaper. First of all you will have to find a replacement ECU from the scrapyard or Ebay. Numbers have to match.
Then you have to find someone who is familar with automotive "hacking". There are two ways to do it:
A, if the original ECU is f**ked big time, and the dump on the processor (MCU) is damaged, so as the immobiliser content, he would have to revert the ECU back to virgin state - so for the MB Star tool it would appear as a brand new ECU bought from the dealership. He would need to do all the coding with the manufacturer's MB Star tool, just like the dealer would do.
B, if he could save the MCU and EEPROM content than those jsut simply need swapping over and you are good to go.
Neither too complicated, but for the A option you need someone who actually has an MB Star (not really a problem, novadays clone tools are quite common, so it won't be a hard task), for the B a simple guy would do it
I would advise you to register on DigitalKaos, and write down your problem here:

or here:

Telling them the exact situation, with data from the car (build year, model number, performance, ECU number and brand etc..), and ask for someone who could do it locally! There are loads of helpful and smart chaps out there!
I would do it for you if we weren't soo far away from each other...

And I was still able to read the MCU content.
