Today I swore at my at my Saab several times
Drove up north for a birthday party. Realised this morning just before I started my drive back that the nearside rear tyre had 15psi in it. Had checked it before I set off on Friday. Front nearside was also down 3 or 4 psi. Had to stop 3 times this afternoon to top up the rear tyre, dropping about 10psi in an hour.
Noticed after a half hour of driving that we'd had icy cold air continually blowing on us despite the temp being set to 19 degrees. Climate control only blew hot air with the temp set to max... Also my OpenSID kept freezing.
Took the rear tyre off when I got home and fit the space saver so the Mrs doesn't have to worry about constantly pumping it up. No nails but a spray of soapy water showed the valve was badly leaking. Front nearside valve also leaking with a little less vigour. They were new at the end of June!
Ran an ACC calibration which didn't show any error and it did appear to be blowing warm air again, however I noticed the SID was displaying external temp as --- and I could no longer ender openSID. So I'm assuming a busted temperature sensor.
Annoying day but thankfully (hopefully) nothing too difficult or expensive to fix.
