Can anyone help? My X5 will start first time from cold even after over night frost or left for two weeks with no problems. If I drive 20 miles or 120 miles and then stop for 2 minutes or 20 minutes the car turns over with plenty of battery but will not start. Of course after trying to start the car six/seven times, battery starts to run down so have to stop trying. If however, after driving 20/120 miles I leave the car for over an hour it seems to start OK. It can be started with booster cables although the battery does not seem to be the problem, I have checked for battery leakage and had the alternator checked, all OK.

I don't know if the following is connected but I have intermittent faults with parking sensors and computer/sat nav screen not coming on. Car has done 80,000 miles.

Have you any suggestions as to what the fault is and how it can be rectified.

I dont think the later are connected.

Im no mechanic at all so excuse my lack of being technical, but have you had the fuel system checked? the pump ect?

cheers for registering, and welcome to the club B)

hopefully some will be no of the problem soon

my CRX used to do this, it was because it was running lean and flooded the engine when turning it off and on in short periods of time

check spark plugs if the plugs are discolored its a good sign where somethings wrong
