recently filled my rears up and the warning light wont go off/stop blinking on the dash display. fronts are 35-37 and rears are around 32-33 currently. what gives?

 

Give it sometime. Drive the car around for several miles. I had this issue. Usually just moisture. Can try nitrogen instead of compressed air. Always a better option.

If this doesn't resolve the issue then its possible you have a bad sensor and will need to take it in to the dealer.

 

Also, the sensor may not be bad. It may have lost it's registration to the system and is no longer being recognized. Again, the dealer can reset it.
