"Last year she struggled at uni and also would not answer any calls or messages then said how she was in such a dark place and I didn’t care about her"
I would be more worried for my DD's welfare than an MOT, especially if you haven't spoken to her for a while. Your attitude towards her seems really hostile here.
In practical terms, the car is in her name, you have given her advice. Give her a month's notice that will not be paying any longer, stop worrying about it and let her stand on her own two feet. Cars, unlike a roof over your head, are not a necessity at university. (Even if you have a placement type course, students manage without).
Your purse strings and your apron strings seem very closely knotted together. You seem to have a lot of resentment towards her and use finance to keep her "answerable" to you. The government expect parents to top up the student loan to the full amount, if their income reduces the loan amount they get (I actually think it's a shit system but that's not the point here). Yet you are paying for luxuries like a car and a holiday then resenting her for it and using it almost like emotional blackmail.
If you could be clearer in when you last spoke to her, your expectation of what "reasonable" amount of contact you would like, and her expectations of reasonable contact, it may be easier to give advice on how to meet in the middle.
