My brother recently bought a non- running 2007 X type Jag with the 2.0 dsl engine from a friend of his . This friend maintains whatever vehicle he is driving to a high standard and the Jag with 150K mls is immaculate - and my brother had admired it for a long time . About 2 mths ago , while returning from Dublin on the motorway it gave a puff of black smoke and cut out . He had it recovered to his local garage , they told him it would cost €1500 to sort so he decided to sell it - and my brother bought it , hoping to fix it for himself . However , the owner of the local garage tried to scan it using a Launch - but could not 'communicate'. He had successfully scanned one or two other Jags previously and has been using the Launch for years now with great success. All fuses , connections etc were checked out but still no joy . A guy who does 'mobile diagnostics ' was then contacted and he felt confident that he could scan it - but he also failed. I don't know what kind of equipment he had but as he does this for a living it must be of a reasonable standard. The Launch will communicate with ABS etc but not the engine . The second guy said the engine in the car is the exact same as that in the Transit . We have made a lot of enquiries with friends in the trade - but Jags are rare enough around here so not much success . So I'm coming on here in the hope that someone may have come across this problem or similar . Fuel pumps often failed in the Transits - but not being able to communicate means fuel ral pressure can't be checked for example. Any help/ideas/suggestions (e.g. websites etc) very welcome .
