TERMINAL 75 LIMP MODE ACTIVE 03789 VCDS

I have searched again on the site but not a lot of info on this. I have asked the dealer on a number of occasions and they refuse to answer the question but I do have a theory. Is this linked to the ignition switch system. I cannot find this terminal on the advanced measuring blocks on vcds system. I'am guessing the steering column clusters. The only problem I have come across is that the main beam flasher element of the switch sticks on especially in the hot summer times so could this be throwing up the fault in the ecu? Again any advice welcomed and has any owners come across this issue? Best wishes.
