I have a 2005 C4 2.0HDI Coupe VTS and have depollution system faulty

Put on the computer and was told egr valve as when driving the car would judder around 2500-3000rpm

Changed the egr valve and cleared all codes and yes its back on again

Was told now that the wastegate needs re-shimming???

Going back on machine tomorrow night but what is meant that the wastegate probably needs shimming as that's what I was told.

Sounds to me like a turbo position recopy sensor fault.
