help needed asap pls

hi all have my mums 1998 p38 dse in garage at the min and basically i need a pressure switch for the abs pump as its faulty and obviously cant get a mot on it with no brakes so if anyone has one or can recomend anywhere i can get one in the northampton area that would be great ive put one in from a jag and it works fine and operates the brakes but the abs light wont go out so any help would be much appriciated thanks in advance

IIRC the "ABS" light/Fault is a "Hard" fault & needs to be cleared by Testbook BUT....... it just "Flashing" on the dash is NOT an MOT failure!!!

My SRS light has bin flashin since 2006 ..... ( I checked the "MOT History" on DirectGov site & Every fooker thats MOT'ed it has Mentioned it!!!!)..... thats 4 garages in 4 different parts of the counrty!!!!!
