Sold my car privately, they are now threating to bring me to court if I don't agree to refund

Hello, I am honestly very stressed out and would like to have opinions on this matter.
I sold my car privately for 680 pounds. the buyer came to see it with her mum who checked the engine and looked around etc. as that was the fourth car she bought in just a few months and they all broke down.
The day after I receive a picture with a warning light on saying that this came up and the car was not starting. I did say that I did not know what was that about but then she never write back. I thought that she solved and everything was fine.
Today, two weeks after, she writes to me again, saying that she is back from holiday and the car does not work, the injectors are to be replaced and it is 900 pounds for that and she begs me to take the car back so that I can sell it again etc. or at least give her some money towards the repairing.
I replied that the car was working fine when i had it, which is absolutely true and that I could not take the car back to re-sell it now that it was broken.
Now she says that her uncle is a sollicitor, and if we do not come to an agreement she will drag me to court as I sold her a broken car.
In the ad I had stated all the issues i know of, I did say that it did pass the mot with advisory last March but that I did not drive it a lot since then. I said about the dent due to the car accident a few years back and that probably the tyres were to be changed as in the MOT it was advisory cause they were worn.
I did not know anything about the injectors, as no light ever came out nor I had issues driving around town. I did say that I was selling it cause I was not using it a lot, which again is the truth. I did say that the car was working fine which was true, to my knowledge, as I was using it to move around town. 
When we met and showed the car I did show all the possible problems I knew of, and showed the MOT certificates and the receipts that I had from services etc, cause I did not want to have it misrepresented.
when she wrote today, two weeks later, she said that I must have known cause something like that happens over time (the AA mechanic said so apparently, she said) but I genuinely did not know. 
Does she have a stand in court? should I be worried? 
edit: I probably must have mentioned, but I did not write any receipt for the money nor done any contract. I don't know if this is relevant.

Private sale.
Sold as seen.
Caveat emptor.
Ignore the buyer.

Ignore them.

Could she argue that I knew about it somehow and win in court?

If she has evidence then that could happen.

What sort of evidences?
I did say that the injectors were changed a few years back (3 years more or less) but this does not mean that I could imagine this could happen.

Some of the motoring organisations offer free legal advice such as the RAC.

 although i'm guessing that the sold as seen will be the main bit of advice given.

 The four cars in as many months thing seems a bit odd.

You can generally only get caught out if the car is not as described or is in a dangerous condition.

I was very clear and described + shown all the issues that I knew of

Then you shouldn't have anything to worry about. Keep all the correspondence to do with sale including ads etc, and don't be bullied by the threats.  If you struggle to ignore the messages/phonecalls, block the number.
