Hi All

Ive just purchased a new (to me) 2015MY 4.4 Autobiography Sport, and while I am over the moon with it generally, a couple of error codes popped up on the IDD tool, as well as numerous out of date modules on the ECU.

My question is how do I get all the updates to the various ECU's, and how do I resolve the following errors

P040D-00 (2F) Exhaust gas recirculation temperature sensor A - circuit high
B13C2-49 (6C) Windshield misting sensor - System internal failure - internal electronic failure

Also the outer silver ring is missing of the audio volume and push on/off of the centre console, does anyone know the part number (if there is one) so I can try and get a replacement.

Many thanks in advance for any help. 2015 Range Rover Sport Autobiography 4.4

John - did you get the EGT sensor replaced? if so what side was it?
