EPC Light On Intermittently

[drlabman]

Hi,

First post!

I have a 2017 A1 1.0 TFSi and I'm getting the EPC come on intermittently and sometimes the EML.  I've had someone look at the error codes and they say it's Charge Pressure Control Actuator: Mechanical Malfunction.  I'm looking for advice as to what this means with regard to repair and what the likely cost might be.  It's done really low mileage so this is quite disappointing.  Any advice gratefully received.  Thanks.
