Good evening you fine people.

I have just had the above error code following a warning light and a 'restricted performance' message. The GAP Tool is telling me this is the EGR actuator is stuck open. (2012, L320, 3.0 SDV6)

Has anyone else had this issue? I can only find two other posts and neither seemed to explain how to resolve the issue and if it was a straight forward home fix or has to go into a garage?

Thanks in advance.
