Damaged undercarriage with large bump on the road

Question about crack in undercarriage covering

I was driving my 24 x5 on an uneven road in the UP of Michigan and after cleaning a large bump with the driver side front wheel, the underside of the car hit the bump and my car briefly got stuck due to the drivers side wheel not having traction. After reversing and getting un-stuck I looked under the car and found this crack in the plastic undercarriage cover behind the drivers side wheel and a little towards the center of the car. Looks like scratched underhood shield and cracked undercarriage cover. My questions are:

1. What is the likelihood of damage underneath the cover (and what components could potentially be damaged)?
2. Is the car safe to drive 7 hrs home, or should I have it inspected by a local mechanic to make sure? Is it necessary to replace it? Is this expensive repair or something I can do myself?

Would help if you posted a picture, just guesses on where it is cracked or how bad.

Sorry just added the pics didn’t realize it did not go through, first time posting

Unless it drives somehow differently I would drive it home. From what it looks like you have gouges in the plastic tray and scratches in the metal. I think highly unlikely you actually bent something structural.

I would probably eventually replace the plastic but from what I can see it should be pretty easy to replace and you can see the bolts that have to be removed. I can't tell how big this tray is or if it eventually get more difficult.

Metal scratches are in an aluminum tray/cover? If aluminum I wouldn't bother doing anything with it.

Just my thoughts.

Skid Plate and Reinforcement Plate look fine IMO....If it's a leaser, I'd leave it alone.,, If it's a keeper than I would keep me eyes on crashed x5 part out

Ok thanks. I think the scratched metal part is aluminum tho not completely sure. I was expecting to see oil pan there but seems like the metal is covering it

Awesome thanks. This is definitely a keeper. Do you know what specific parts I should be looking for? Definitely a newbie, found some diagrams online but they are very descriptive

Put your car's info in at https://www.realoem.com/bmw/select.do to find diagrams & BMW part #s to shop with. Realoem doesn't sell parts & the prices are outdated.

I'm pretty sure RealOEM stopped working a long time ago. It has stuff prior to not working but nothing for 2024. I'd love to be wrong but I think that's how it is.

Agreed there's probably no damage. As far as the part... you could probably go forever and never know anything happened. Otherwise, agreed to find the part perhaps used and be prepared to pay more than you'd have expected.

The skid plate is not terribly expensive . A little bit over a Benji. The refinforcemnt plate...didn't bother doing a quick look as they must be expensive if my memory is using the cost of the bolts as a reference. It's a TTY bolt, and I recall paying a kings fee per bolt on those.....had me second guess whether I should re-use them or not given it's cost.

Metal stiffening plate is a structural component on xdrive cars. If it is compromised, replace it.

I think that your in the clear, as long as your don't have any liquids dripping. I would just replace the broken plastic undertrays.
