2011 135i Engine Ticking Sound When Warm

[J600RHO]

Hi all,

Bought a 2011 135i around a week ago and just noticed a ticking sound coming from my engine bay, I'm aware the fuel injectors make a ticking sound but the sound I'm hearing sounds more like a metallic tick and towards the front of the engine.

I'm also aware this can be a lifter tick but this sound is still made after spirited driving and the oil sitting at around 100 Celsius.

Not sure if related but on top of this I'm getting an error code, 002BC0 (Fuel-air mixture too lean). Here's a video of the sound.

If I'm crazy and this is normal sounds to be made from my N55 just let me know, thanks guys.

TLDR: Ticking sound when engine is warm and cold + lean air-fuel code.

sounds like fuel injectors to me. hood open and beauty cover off will make the noise very pronounced.
