Hi everyone,
I'm working on my 2021 Citroën Relay van (registration ND71 VDZ) – it's the 2.2 BlueHDi diesel model. I'm trying to locate and replace the EGR valve (and possibly clean/check the EGR cooler) because of suspected issues. OBD CODE P046C
I've removed the engine cover and taken some photos of the engine bay (attached below if the forum allows), but the rear area is super cluttered with hoses, wiring, and brackets. From what I've read, the EGR valve should be at the back near the firewall, often integrated with the cooler (small rectangular unit with coolant hoses), but I'm struggling to spot it exactly. Any tips
?
Exact location on the 2021+ 2.2 BlueHDi – which components to move out of the way first (e.g., specific bracket or hoses)?
Common pitfalls or things that go wrong during replacement?
Also, if anyone knows how to confirm my exact engine code/sub-variant from the registration plate (ND71 VDZ) or VIN – I'd really appreciate it! ( I ordered a Haynes manual and need to select the engine model)
Thanks in advance for any advice, photos, or links – much appreciated as I'm trying to DIY this to save some cash!
Cheers,
