EML and fault codes

Michaeljf93 · 03-26-2024, 11:09 AM

Hi all,

I have had the engine management light come up on my f30 320ED and have read the fault codes using bimmerlink.

The codes were -

290900: Air system, air to EGR mass flow plausibility: measured air mass too high compared to calculated air mass.

24BF00: Zero quantity adaptation injector cylinder 2: Permissible filtered control duration correction too high.

Am I right in thinking the first error is a vacuum leak somewhere?
And the second error means a new injector is needed? I did try some Wynns injector cleaner but the error is still showing.

I don't have ISTA so unable to do any further tests but would the first port of call be looking for a vacuum leak? My car isn't part of the EGR recall so I don't think it's anything related to that.

It did have a new lambda sensor fitted about a month ago (the one after the cat) but again I assume it's nothing related to that? The car seems to be running fine apart from the EML light. It is a little rough sounding when first starting in the morning but as soon as it fires up sound fine.

Thanks in advance,
Michael

Just an update and maybe help those in the future!
I did a smoke test and found the intake manifold had a leak where the swirl flap rod enters. Replaced the intake manifold, did another smoke test and it's all now fine! Was pretty badly built up with carbon so kinda glad I replaced it.

The injector error was a bad injector and a replacement has now sorted it.
