Will a 2007 mondeo 2L dtci engine fit in a 2007 transit 2.2 tdci if I use the mondeo ecu ?

There are usually slight territorial differences so find a diagram in the vehicle handbook or ask your local Ford dealer.

Andrew, Ford Focus 2L tdci computer box, ECU's are repairable sometimes, if not normally no charge. You would have to google search for a repairer in your area, search Ford ECU repair/testing. As Ray G. suggested you could probably get one at a local auto wreckers, may have to be programmed or flashed to your vehicle by a good Tech. with proper equipment. Check the attached links,instruction and guides, Good luck

Compression Ignition.
