Hi folks. I have a 2010 z4 35i and have fault code 29E0. I know this means I'm running lean somewhere. I have Carly and was wondering if there is anything specific I should be looking for in live parameter data that could point me in the direction of the cause. Any feedback would be appreciated. Cheers

As E-BMW said above; you need to check the air intake side carefully and see if there are any splits/loose connections letting extra air in after the MAF; this is generally the main cause of lean codes...P.s car has had engine rebuild a couple of months ago, has new plugs, coils and pre cat o2 sensors.
If that's all OK; maybe give the MAF a clean with dedicated MAF cleaner and see how it runs then also
