My 1.9 sporting has developed a flat spot. it only happens under certain load levels and boost levels. it never happens on mid or full throttle tho.
it does it when its cold and going up a steep hill in 2ND or slowly acceleration in 3rd, going up to about 3k. My cars has been mapped. As said it only does it occasionally but when it does it, i can here the waste gate going off then the sound of the turbo building up boost again. it still boost fine on full throttle
The cars an 07 plate so maybe failing turbo? Its been about 2k miles since the last oil change. any ideas what it could be? i
