Unusual scraping to under flooring

richieg888 · 09-12-2023, 10:50 PM

My car is 2018 N55 M2 LCI
, stock suspension. I recently noticed that I have been scraping the bottom floor of the car in angled driveways and speed bumps , I took some pics of the bottom of the car and found this today.

Is this protruding piece of metal normal ?.

Definitely not normal but I’m pretty sure that’s just a damaged felt/plastic under tray and not metal. Looks like a thread hanging down in the blown up pic.

Just a follow up to this post . It was my undercarriage / bottom flooring that snagged . There is air inlet in the undercarriage that got caught up and ripped off a steep parking driveway . While waiting the replacement part , I did some research online to use gorilla tape to patch it up. Attached are some pics .

your NACA duct is missing, you have the leading edge but the scoop portion is gone. You will likely want to replace it so your gear box gets proper cooling.
