hi, my wifes car has started losing power. its an 02 1.9tdi ambiente.
it starts fine and will run great initially, after a min or two of giving it a bit of stick its like it goes onto 3 cylinders, no power as such, you have to gingerly press the pedal to get an increase in speed, if you sink the pedal it just bogs right down.
if you pull over, switch off then switch back on again everything is fine, you can boot it in 2nd or 3rd but when it hits 3000rpm its like what ive read "limp mode"
ive pulled the maf sensor and its just the same, one thing i noticed is quite a bit of air in the clear pipe going from fuel filter to engine, when revving the amount of air running through the pipe increases with revs. with engine stopped there is always a bubble in middle of pipe about 20mm. it must be drawing air from somewhere as i take it this isnt normal? would this cause the problems described?
sorry for a bit long winded :oops:
