not gotten that far, but according to Haynes its remove a screw and pull out, similar to the front.
Well as a further update, I did a bit of digging through my bank statements, I recalled paying the deposit of £100, turns out I paid it on my Barclaycard - excellent! called them up yesterday, gave them the story, they cant promise anything but they are going to send me the forms and see if they can get me the money back. They just need as much evidence as I can provide them and they will argue the call for me. I am going to request a refund based on the sale of dangerous goods, and also breach of verbal contract. I know there is little chance of getting the money back but it has to be worth a shot!
So playing the waiting game, will see what can happen, I am going to keep trying to clean the ABS but the rain is terrible today so that wont be happening today.
Three ways to go from here:
1) I get a full refund and shot of the car if I win the case
2) I get no refund, try and fix the car and hope to god theres nothing else wrong with it
3) I get no refund, car proves impossible to try and live with, I dispose of the car by some method of sale (private, ebay or to someone like webuyanycar.com for around a grand) and then buy a high mileage with receipts from a private seller for just under 3k, using my credit card.
So there's a third chance I come out of this better off, a third of a chance I keep the car, and a third of a chance I remained stuffed...
