My W210's compressor seized, the system with the thermal fuse worked as designed. I would not want to risk bypassing this. If the compressor seizes and it does not disengage itself you will shred the belt and worse.

606 turbo compressor not all that hard to remove, you do have to get the intercooler pipe out of the way first. Once you do that the compressor drops out through the opening in the LCA.

Also remember that these are Bxxx or Body OBD codes. On the 1st gen W210 (which all the US Diesels are) only Pxxx or Power train codes come out of the OBDII port. There is a bridge between the Body and Power Train CAN buses through the ignition switch but the B codes do not pass through to the P bus.
