I do have Fabia 1.4 tdi Bnm engine. Off late when i try accelerating too much my car is not pushing up. It revs up with loss of power. Not even able to overtake as it’s not producing power. What should I do ?

Clutch failure?

No clutch is good, I feel fuel is not supplying properly in higher speeds.

@Sathishsaty - If you think you've got fuel starvation, the first thing to replace is the fuel filter!

 

If that doesn't solve it, get the codes read.
