Noticed an occasional holding back in low revs like an ignition coil failure but not misfiring. Initially thought it was under powered engine as I have the 116i 1 Series but I took it back to the garage for further checks whilst still under warranty.

The fault recorded was 2F08 - Air intake sensor signal and a unknown 2008 fault code stored.

Additional notes on the diagnostics was that intake air temp reading 42c seems high

Recommended futher testing by BMW

Any advice on what this fault is and what it may cause?

It can happen with a cold or warm engine and any gear but always under 2500rpm and only for a split second but it is noticeable.

I've managed to get Evans Halshaw to pay for a proper BMW test so I will book in there and update further

From reading common faults on here I see MAF and ignition coils or injectors are pretty common and they would tie in with the engine symptoms

I just don't want them avoiding fixing it while it is under warranty
