Infotainment System 2010 XKR - Outside Ambient Temperature

[Mike Y]

Hi all,

 I’m the owner of a 2010 XKR 5.0 Supercharged.

The outside temperature on the infotainment screen flashes between ambient and -40°, when this occurs the HVAC fails to operate (including the blower). Occasionally the issue resolves itself and everything related works as normal until the car is restarted.

Battery has been replaced along with ambient air temperature sensor (nearside door mirror).

I would be grateful if anyone in the group has experienced/remedied this before I go down the diagnostics path.

Thanks in advance,

Mike

Hi Mike
I had exactly the same issue on 2013 XF Sportbrake. Totally confused the garage as not fixed after replacing the external sensor. It seems the computer still relies on previous readings until the car has been turned off for over 6 hours so, fingers crossed, it may be OK when you have left it overnight.....

Good luck

John

Hi all,

For information, the Climate Control Unit module (passenger footwell) was defective. Impossible to reach screws, so just cable tied replacement unit to defective unit.
