Here are some solutions ofTCS CDP(cdp pro) running on BMW and Mercedes-Benz cars.

The reason that some CDP PRO cannot work with BMW or Mercedes-Benz:

The OKI chip is only for cars that support the PWM/VPWM protocol like Ford. BMW didn't use the PWM/VPWM protocol.The info that the TCS CDP does not work with BMW and Mercedes is bullshit.

The essential reason is located in problem with the m6636:

The problem with the m6636 is in the CDP pro not in cdp+. replace the 2 diodes and check if it works. the 2 diodes is for bmw and maybe mercedes, honda and others.

Solution of CDP PRO with BMW cars:

the 2 diodes areD701 and D703. back the pcb. And replace it with 1n4148.I have replaced these two diodes and gained the communication with BMW cars which users could not communicate with before. So, well DONE

Solution of TCS CDP with BMW cars:
You have to know that the components for TCS CDP interface, removed from old devices like tv´s, radio´s etc. check all solder Joints of all components (especially relays), so I have fixed the problem. I use the same interface for all BMW cars and it works without problems.

If solutions above doesn’t work also, spend a little money to buy a new TCS CDPunit tested ok.

ThisCDP PROwith 2015r3 software works without issues on BMW 3 series e90:
