1.4 16v BBZ/AUB engine - I went to remove the EGR with a view to cleaning it up to see if it would help the emissions. The car scraped through the emissions test on the last MoT. I was surprised to see this short hose to what looks like a non-return valve, which just appears to vent to atmosphere. I can't see an open hose anywhere, or a stub with no hose attached. Is this correct? Is it missing something and if so, can someone tell me what and where? I'd expect this to be the vac line that pulls it open.

Don't know why only one pic embeds, but they are two different shots.

It is correct, it's a vent, the EGR is electrical, no vacuum.

Yeah, a pic of an engine from ebay (BBZ) shows it just hanging and looks like it's meant to be like that...

Which aspect of the last emissions test was marginal? CO? HCs? Lambda?

Not sure the EGR valve will be relevant TBH.

Thanks all, one mystery solved. Will have to dig out the cert to answer the question on the test.
