Hello and Welcome -

My name is MIKE,. Im happy to help you ..

The first thing to address with this Steve is the EGR system - faults here can have a knock on effect to the turbo side of things - so this is the first area of approach.

The EGR valve needs removing and thoroughly cleaning - some garages have a device that connects to the Egr valve that manually - off car, as it were, checks the actual operation for correct operation of the valve - and in so doing, if its proven ok, it can be used to open it to clean it properly... If its proven faulty - replacement is the only answer.

Too -its very important to clean where the Egr valve sits - this may mean removal of the manifold etc - but its important as if its clogged inside there - the valve code will come up - even with a new valve on.

Usually this as above will cure the whole issue - one way or the other as above - ie, cleaning or replacement of the Egr... but if not - if you then get the turbo system code back, you need to have the turbo system properly checked for boost pressure etc - that will find the fault there then ( again , if still there if after doing the above )

Best Rgds, MIKE.
