Bmw x5 is loosing power and shuts down when taking foot off excel

could be suspension or wheels out of round. Bent rims etc...

Very expensive. Try all of the above. If they all fail then last resort is a complete system reset. Disconnect battery for 8 hrs. Reconnect and start car. Do not lock doors or else leave a window open when you do this. Car will not unlock or allow you to open any hood liftgate etc without battery.

You will most likely need to pull the fuel tank out and replace the fuel module.

Hey Chuck, run a bottle of fuel injector cleaner in a full tank of gas and see if that takes care of the problem.

Did the car store or was not used for a while or been in an accident I think the (float ) level for the tank has been moved or broken Like in a toilet if the float does not work water will run for ever In a mitsubishi shogun pajero the tank is easily approcheable on the rear of the seat I ' m not sure on the BMW Best ask and get your mechanic to change it Good luck

check for broken alternator drive belt
if broken the battery will be flat

We had a 2001 X5. When the Fuel gauge hit 1/4, it was time to fill up or you were stranded. I think it's the pump if it is below 1/4. We also received error engine codes when this happened. All you have to do after you refuel is to reset the code (drive with the code for awhile, it will reset after a few miles) and you're alright. The pump is somewhat expensive to change out if you take it to the dealer.

Normal. There is a resister in the fuel level circuit that slows down fuel level readings. A gauge that responded instantly to a sloshing fuel level every time you went over a bump or around a turn would drive you crazy.

was this problem there before replacing battery? if not a loose connection at battery or in battery compartment the code is a temporary code and when connection severs the code is cleared check the time after starting till problem occures and see if there is a pattern to how long it takes

go 2 autozone and have them do a diagnostic scan and clear your codes this will shut off light and the service is free
