My car fails to reponse when I press the accelerator flat. This problems persist for up to about 10metres before it starts to respond again. It mainly happens when I press the accelerator quickly at higher gears does any one know what the problem might be. Back here there is no mechanic with diagonistic tool and no BMW dealership. I have serviced the car, changed the petrol and oil filters, plugs and engine oil. The mechanic told me it may be the fuel pump as he measured it and it was 2.5 but should instead read 3. Also the ABS light is on but the bake pads where recently change is this what is affecting the car?
