I ran into a problem at the tire place (les schwab) saying that the "tire pressure monitoring system" was corroded to the valve stem and couldn't swap the sensors over to my winter wheels.

I went to a second party BMW auto shop and he quoted me $100 each ($400) total for new pressure sensors for my winter wheels.

So I guess I am asking if there is a way around the TSP warning light just for the winter? or am I kind of stuck paying $400 for the sensor & tire stem plus whatever it cost to mount and balance the wheels?

Also is there any cheaper place to buy these sensor other then the dealer?

Thanks for all your help,

Montana Guy
Several questions are in order here. How old is your car? Are you out of warranty? Do they use salt on the roads in your area? Did the BMW dealer confirm the corrosion?

They do have "rebuild kits" for these TPMS but it's difficult to imagine the extent of corrosion you have. All four would be strange IMO. A TPMS can be ruined by a shop inserting a brass valve core during tire service vs. the required nickel plated valve core (prevents galvanic corrosion).

We rarely hear of TPMS corrosion issues in here.
