Hey everyone

I have a problem with my X5, when im driving around 50-60 mph, the car seems to dip the revs then revs up again, its only doing it sightly, doesnt do it when at idle or when i do over 60..

car will be running at 2000-2500 rpm, and you can see the needle drop and then it revs back up to normal, its doing it all the time any help will be brilliant
