1.4 TDI - Loss of power to turbo

Post by mikey2127 »

Good Afternoon,

I have tried to have a little scan through the forum but could find anything - sorry if I’m repeating something already queried/posted about.

I have a 1.4TDI and recently, the engine management light has come on. When reading, it comes back with a code that suggests theres a loss of power to the turbo.

The car runs fine until going up hills and there’s a significant loss in power and subsequently speed.

Garage has said there will have to be a full pressure test on the engine and that sounds fairly costly.

Any suggestions?

Thank you in advance

Hi and welcome to the forum

If you could post the codes retrieved from you car by the scan tool this will help diagnosis

Possibly stuck turbo vane actuator.

Good a morning,

The error code reads ‘P0299’ and it’s a ‘Carista’ wireless reader

Below 30k Revs there is no obvious loss in power.

Thanks again
