    DEF fluid

    John Mcpartlan posted a topic in Jaguar Technical
    I have a XF 2l AWD sport. For 2 years I have been topping up the def fluid with fluid from Halfords with the correct iso number. The car recently displayed a message that incorrect quality def detected. I took it to an independent Jaguar specialist who said it would need a new def injector and be refilled. He said it would take 2 days as he had to order the injector. After fitting that he now says the car is showing another fault he doesn’t know what it is that’s wrong. He is blaming me for using Halfords fluid. He has now had it 5 days and it still not fixed any ideas as what else could be wrong as he doesn’t seem to know
