C5 Driver Lumbar not working!
The pump coninuously run even after the car is of, eventually killing the Battery.
I disconnected the main connector along the side to stop the pump.
Suggestion on troubleshooting, please.
Is there a pressure sensor in the system and possibly a leak in a line?
Thanks,
Luis

If the pump is continuously running its probably your switch on the seat which has gone south. You could pull it off and see if you can free it off. If not, I'd say a switch change will probably do the job.
The switch connects via a connector block under the side of the seat. Pull the conenctor and see if the pump stops. That will isolate the problem

Thanks, Disconnected teh main harness as you recommend, The pump did stop. but also all other seat motor controlls are disabled.
I am looking for a pin or connector diagram to help isolate the problem.
