The car is a 2001, I'm not sure if that makes any difference, but other than that Bob is 100% correct. I have been to 3 shops plus the dealer and none of them have been able to get to the bottom of the issues. This last time, they told me the SDS said the pressures were ok, which is obviously not true since you evidently can't check them with that system.

I will give Continental a call today.
