Unknown Fault P2034

So the D4 has been in having a couple of Warranty jobs done along with a RH manifold. after a test drive, they've had a Restricted Performance error pop up with code "Unknown Fault P2034". There doesn't appear to be any actual restriction in the performance and the way it drives. They have spoken to LR, who are unable to shed any light on the issue. One thing they noted was that an EGR blanking plate has been fitted. A quick google of the fault code tells me it's an Exhaust Gas Temperature Sensor Circuit issue.

Has anyone come up against this issue previously, or point us in the right direction? we're currently scratching our heads.

Thanks in advance.

Could the blanking plate be leaking exhaust gasses?

I suppose it's worth checking. Thanks
