My electrician used several other tpms control units but we keep getting the tpms inoperative on the dashboard although, my brother drove the car into flood last year but there was no issue with the tire pressures just the central gateway and parktronic sensor control unit that had to be replaced because of the flood that got in. Now, I'm confused as I'm not able to get any fault on the diagnostic device under tpms. The only tpms related fault I get is "Control module TPM (tempomat) Tempomat not sending any data - current and stored.it's just too frustrating. What else can I do please?
