1st time Jag owner : 2005 XJ8 L - 46,000 miles

Just noticed that when the heat comes out of the dashboard, the heat on the drivers' side is cold, while the heat on the passenger side is hot. After the car has been running for awhile, the driver's side warms up but does not get as hot as the passenger side. Any idea why?

Air Suspension Fault light recently came on.. When I called the dealership, they said it was most likley due to changing the back tires and to bring it in and they would reset /or calibrate the compressor. Does this make sense to anyone out there.. Would the air suspensin fault light come from changing both back tires?

Many thanks..
Still lovin the Ride
