Ok,

One week before i came to Spain i bought a 06 TDV8 Khan RR.

Since im STILL in Spain i let my brother use the car and i have recently bought another one out here, only not a khan and on a 07.

Ive been in the UK last week and final got to use the Khan. NEVER LET YOUR BRO USE YOUR CAR !!!!

Parking sensors NOT working (nether are my ones in Spain), Suspension fault max speed 30 mph warning on dash, its only averaging 20mpg, the one in spain does 30mpg, it was filthy and was being serviced at the local garage !!!!! WHAT A PLANT POT !!!

On the mpg side of things could it have anything to do with the wheels throwing the computer out ? its on 22 ?
