Customer Question

Recently bought a 08 bmw 320D Edition M Sport with 57k miles. All running perfectly for first 3k miles then I notice less mpg and 6th gear and sounding a little rough at about 2k rpm and same in 5th gear. Filled tank with deisel and added some dipetane, thinking maybe injector blockage. No change after a few hundred miles. Waited for car to warm up on motorway and drove in 4th gear for a few miles at 3.5k rpm. Still no change and I suspect getting worse. .. any suggestions would be appreciated. Thankyou
