Very common on the E9x & E6x but not on the E46 M3 CSL, fortunately
One other way of safeguarding your E61 M5 Touring O.E. is to relocate the OBD socket somewhere less obvious but leave a dummy one where the original should be ... or better still put some sort of an electrical short in there so it'll fry the potential thieves equipment when they try to code a blank key to nick it
It's what I did on my E60 530d
