1.6 Fsi lacks power above 3000 rpm

Since I bought my Fsi in December 2015 I have been complaining about the engine performance. I called it lame and no high rev temperament. It also hesitated during acceleration.

VCDS presented only one engine error:

17428 - Fuel Pressure Regulation Control RangeExceeded P1020 - 35-10 - - - Intermittent

The hesitation was solved with cleaning the trottle valve.

But now I think I have solved the performance issues above 3000 rpm.

I have removed the intake manifold and have cleaned it. I have also replaced all fuel injectors, the HP fuel pressure sensor (G247) at the intake manifold, the
fuel pressure control valve (N276) and the intake manifold pressure sender (G71). And at the same time I replaced all gaskets.

I sent the old injectors for cleaning and test. They started with a test before anyting else and they passed it (no error). I recieved a test protocol with date before and after cleaning and only 1% improvement on one injector. The result shows that the injectors was not the problem.

I have made a test drive and I feels ok and rev happy above 3000 rpm, and no error code, yet!

Hello,

I encounter exactly the same symptoms on my a2.

Since your last post, does the car still works well ?

Thanks
