Diagbox tells me the downstream one is faulty, rough running but no eggy smell). Can anyone tell me what the OE part used actually is (manufacturer /part#)? so I can get the right part to replace it with? (same as C1, aygo, I understand)

I'm sorry to forget obviously needful information. 65 plate, 1.0 vti unsure of PS.


  • What year (or plate number) is your Peugeot? What engine does it have (incase there is more than one offered for your year)? Actually, I'm seeing three different engines offered for the vehicle. – Pᴀᴜʟsᴛᴇʀ2 Oct 15 '19 at 21:16
