Dash lights fault

[Leeg]

Hi all, not been on the site for a wile due to working away. Wile I was away I let a family member use my x5 and there is a couple issues on my return, he said that he didn't see a speed bump till very late and braked very hard and after going over speed bump some lights came on the dash,
1) abs.
2) ! Symbol)
3) one other iv not had chance to check myself yet but think they are all linked as they came on together, I'm thinking a sensor has been dislodged or damaged, or something along them lines, any suggestions...

the central locking has stopped working on the key fob, also the central locking button on centre console does not work. 

Thanks in advance and my apologies for first post in a wile being a bombardment of questions.
