Mein Auto: 05 X5
X5 Surging between 30-40 mph

My X5 has this "surge" issue. Between 30 and 40 mph (this is where I notice it being bad), it sort of surges, almost like it's cutting out or has a bad tank of gas. We took it in expecting system updates to cure the issue with no success. Now what? It is at it's worse at cruising speed with only a slight amount of pressure to the gas pedal, and when it happens, it's significant enough that whomever is in the car can feel it (not just the driver). BMW has been no help in fixing the issue so far, and we just bought this car 3 months ago, and it has had this issue since purchase, yet we're still chasing the issue and not certain if this is a bigger problem and worth returning to the dealer or not. Any direction would be a HUGE help! Thank you!

any other funny things happening to your car (ie: brake light warning, engine light, horn not working or horn activates interior lights, rain sensing whippers not working, air bag light is on, cruise not working). My 04 x5 had power surging issues but i had other weird symptoms as i mentioned above and turned out to be an ignition switch, $40 part or $360 to have the dealer fix it. hope this helps

also could be your throttle body, i had my throttle body replaced as the vehicle would die when the accelerator was pressed. car would idle fine and it was temperamental but it may be your throttle body causing the issue.
