Power loss over 2nd gear
Hey!
i have a 520d with a problem.
when i drive in 1st and 2nd everything seems normal, but when i shift to third and get to 80km/h and 3000 rpm the fuel consumtion needle drops to 1L and it stops accelerating. It just stops gaining speed. And if im going uphill it gets worse, doing just 60km/h up a hill in third gear.
I checked for codes and got 447B lambda/oxygen sensor fault. Tried unplugging it but nothing changed.
Anyone had something similar happen?
