At least 4 years, as long as I have had the car. At $300+ I am only changing them if I know them to be bad

Today I drove it in the rain and through quite a bit of standing water, still zero related miscues.

Looks like I can start chasing other issues... like:
1. The ABS and PSD warnings that seem to occurr about the first substantial bump I hit after each start-up. (new problem starting from when the shop returned it )
2. The volt gauge dropping to zero on occasion, for long periods of time. This has been around for a year or more. I am hoping it is a pod ground issues, as I have a recovered pod to swap in anyways.

So no more temp related limp mode issues, thats great to here.

The ABS & PSD are linked.....when was the PSD last serviced?


Its essentially a brake fluid flush using the digi pod or Theos diag system through the diag port.
