TPMS Woes
My Cabrio just started developing "Low Tire Pressure" issues, though the tires when checked with a gauge are just fine.
I own an iCar-MBII and looked at the options. The system memory reports the correct settings and the recalibration mileage of 89,610, yet the "raw data" from all four sensors reads ZERO bar/PSI.
The car is 2009, so I think it's time to replace the sensors, but I'm wary that ALL FOUR went dead at once. Communication to the TPMS module must be OK or I wouldn't be able to read set values and sensor addresses.
Does replacing the sensors seem like the right path? I have to replace rear tires anyway because mine chews up Hankook S12's in about 10K. Twice as fast as the fronts. I'm going to get it aligned once new tires are on since it could be a toe-in issue.

Aww shucks! I kind of liked my MB Valve Caps. I've not seen any evidence of corrosion, so these caps are most likely stainless.

I had those too but ditched them. As I said (in another thread, if anyone's confused), in a salt-free climate you might get away with it, especially if they're stainless, but it's just one more thing to worry about.

Alignment is not going to aid you in getting any more mileage out of your rear tires.
I bought this car 4 years and 30,000 miles ago so it seems an alignment is overdue.
