Could the engine fault code P00AF indicate an EGR problem.

Thanks for your reply Steve, I appreciate your advice.

I was going to have the actuator changed at my local garage but they say I can’t just change the actuator, I have to change the whole turbo, is this correct?

Paul, thanks for your reply your advice is most helpful, I forgot to mention that the fault always occurs when it is in cruise control, I don’t know if this means anything.

Can anyone advise what the problem could be on my 2013 A4, the engine reduces in power, the glow plug light flashes and the OBD fault codes are P00AF and P0234
