x7 failing emissions

Unread post by Agour »

My 2009 x7 failed the MOT on emissions today..

Diagbox shows P1471 — EGR valve, logged as Local, Intermittent, with the fault characterized as an open circuit.

I've attached photos from the live readings (engine on).

Seems to work fine for 30 seconds or so - but then the "no EGR" kicks in.

I assume the EGR is knackered, and this is causing the emissions issues?

Would anyone be able to tell me the exact part number for my vehicle too please? :)

(or point me in the direction of where I can find it..)

VIN - VF7**************[VIN obfuscated, can be read by forum staff]

Thanks!

Does it have a DPF?

yep! I filled up the Eolys 6 months ago or so.

All readings for DPF seem ok on diagbox? (photos attached)
