Have a 2003 RR HSE with 86,500 miles. The other morning it got jumpy (almost like running out of gas) when you hit the accelerator to go above 15/20 mph. It is at the shop (local ind. BMW) and they have eliminated some ideas and think it may be the fuel filter.

Any RR quirks that may help them diagose?

Thanks!

 

possibly, could also be a broken hose causing a lean code.

 

checked hoses and erg computer? all ok so far. Hoping it is not the fuel pump

 

Are you getting any mis-fire, engine to lean/rich, etc. codes? My first thought is, when was the last time the spark plugs were changed out?
