I'd really appreciate any help with this. I just installed a MAD BMW cold air intake on my vehicle listed above and I am now experiencing problems. Just after installing the intake, the engine was fine (with idling/small revs), but after starting it up again after a few hours of not driving, the engine is making a lot more noise and rumbling very loudly.
The engine bay noise (standing outside the car) is noticeably louder, and inside the cabin, there's a very loud rumbling/shaking noise. I checked all of the clamps, and everything seems to be sealed correctly. Would it possibly be a MAF sensor error? I'm not sure if this would relate, but I accidentally dropped a wrench into the engine bay, that I haven't been able to get out.
First time modding my car, and hope this isn't a major issue. Thanks for any advice.
The audio is linked to soundcloud, and is the car starting -> idling.
