I have just joined so I hope this message appears and I don't drop any clangers! I'm in an emotional dilemma so if anyone can give me views on this I will be very grateful. I own a 2004 Jaguar XJ6 in Green, 105,000 miles, which I've owned for ten years which I bought from my late brother who had it for four years, so it has family sentimental ties. The car is a real looker and has just purred along incredibly well but has now developed an electronic problem. It starts and runs great but warning signs are showing relating to ABS fault, engine management, speedo stops working (after five minutes) and traction not working. I've had the private garage to check it over on the computer and he confirms the ABS has failed and two rear sensors. He says the ABS affects all the other info. Is it worth me repairing for about £2K - will I likely have another problem and start to throw money down the drain. I've been offered £500 scrappage. Is there a private expert in this line (I'm based in Yorkshire). Thank you if you can offer advice. Keith
