this could avoid to mess with brake oil bleeding
an used M3 ABS block could do the trick or has it to be new?

You'll need the M3 longitudinal sensor and M3 SZL (clockspring) as well. Make sure you get the right clockspring for your options, rain sensor, xenon, etc. I don't know if you can get the module off the ABS block without pulling it all out but you might as well because you'll need to run a wire from pin 41 of the module connector to the appropriate pin on the back of your DTC/DSC switch or you won't be able to turn DSC off. The M3 is directly wired while the 335i is ran through the JBBF. You may or may not need to replace the wheel sensors since your car is older. Mine is a 2013 and it was fine. And of course you'll need ISTA and BMW Standard tools from bleeding, DSC valve calibration, steering angle sensor, changing the VO, writing the VIN, etc.
Used is fine. I bought a complete unit used for $300 USD.
