New to BMW forums and looking for some assistance with a 1 Series M having TPMS issues. New rims and tires put on by Discount Tire and all worked for a month, now getting TPMS "Inactive" error on dash. DT says they can scan the sensors but can't clear or re-learn. BMW dealership said they were intermittent in their scans of the sensors and that the RDC is probably fine but needs brand new TPMS sensors at a cost of $200 per sensor.
I have searched parts websites that deliver full kit of 4 sensors for only $250. Why is BMW dealership 4 times the cost? Can the cheaper sensors work with the RDC unit too?
