Update as to what's happening. So far they have changed over pretty much everything. ECU, Chip, Injectors and Relays. They seam to think it's a wiring loom fault causing rear injector not to fire every now and again. So a new loom is on its way. They have informed me that Ducati is picking up the bill for the rockers and cam and Manchester branch, isn't going to charge for finding the fault.
So all being well should be back with me just ready for the snow
But can't complain if they are picking up most of the tab especially whilst it's out of warranty.
