I recently purchased a W Reg V70 T5, 80k on the clock, not yet too familiar with the car but now find turbo lag more pronounced at some times than others for no apparent reason.
Today I put my foot down at about ten mph to nip out into a trafic stream and the engine just would not pull or rev for about ten to fifteen seconds, giving me quite a nasty moment and some not too complementary gestures from the guy bearing down on me at a rate of knots.
Afterwards I tried to reproduce the same conditions and the engine seemed to work O.K. An hour later the "thing" let me down again when I needed the acceleration it just was not there.
Anyone else had this experience.
Regards, Brian.
