I am buying a portable battery jump starter pack and have found one that says it will start a engine with a "400A crank power", is that suficent for a 3.0 Sports Diesel x5 Many thanks

400 amps is enough to crank a diesel truck.Amps referes to draw , so you will never actually pull that much but will have it if you need on something else.

Bmw x5 2003 03reg diesel onboard computer says fuel inject.system when i acceleration is all the way down then is not driving same like before i have to stop and start ingine to come back to normal .


I am presumming this is a diesel? please confirm.

It sounds like an EGR fault, exhaust gas recycler valve, this will make the car lose a lot of power and cause the engine light. Normally will not rev over 3-4k rpm with the light on.

My fuel injection light came up on the dash board of my bmw x5 3.0 diesel. What is wrong and how much will this cost to fix.

You will need to check your fuel pump and your injector nozzle in the engine. You will also need to check that you have enough fuel and your fuel indicator is working well. Injector engines usually do not tolerate low fuel levels. As for the cost of change, it will depend on where you are and what type of auto mechanic you are dealing with.
