They allowed me to take it to a local garage who told me what I already knew about the check engine code being an egr fault but when they looked they said it appeared to be a brand new egr valve and there was a rusty pin on a multi-way plug so that was cleaned off and test drove with no fault. I took the car back and within 10 miles the light is back.
Anyone have any ideas?

Normally that code would indicate a blocked EGR cooler.
