I changed the fuel filter housing on my 2.0tdi BKD last Saturday as it developed a leak, it ran fine Sunday. Monday morning driving to work and when changing from 3rd to 4th the engine loses power and judders, then same thing happens going through the gears up to 6th. If you ease the power on gradually it's not as bad, and it's worse going up hill. There's no warning lights showing up on the dash, and it's not showing any fault codes either.
Has anyone got any ideas what it could be or how to sort it?
