This is a Ford design engine, the Puma family, on a traditional Bosch VP30 rotary lobe pump. It has the advantage that the same engines were used on the Mondeo Mk3 until 2006. Then Ford in Mondeo installed PSA engines, and in Transit still Puma engines. This Transit has the designation 2.0 tddi, while the strongest was 2.0 tdci, i.e. common-rail - it had 125KM.
The 2.0 tddi 85KM engine is considered to be the least emergency among the Puma family, because it is not very powerful and the injection pump has been known for years. If something is wrong in the injection system, then the pump controller (injection angle adjuster transistor) or the pump controller itself.
The engine has a timing on a chain, 400 kkm will definitely go for replacement, but sometimes the mileage is much higher. This engine version has a simple, single flywheel, so there is no costly replacement of two masses.
There was an even weaker version of the 75KM, basically the same as the 85KM, except that it had no intercooler.
Garrett turbine with wastegate valve, which is the simplest solution, basically reliable. Vacuum-controlled EGR, sometimes it cuts - as in all cars.
In winter, it burns great even after a night in severe frost, with half a turn, but it does not heat up, especially in city driving. On the road, after twenty minutes of driving at a speed of over 100 km / h, he will catch the temperature. In temperatures above zero it is ok, it heats up faster. In Mondeo, electric heaters were installed to heat the fluid in winter or independent of the webasto driver. Not in Transit.
With a quiet road ride of 90-100 km / h, a small, short Transit 2.0 tddi will burn about 7l with this engine, but in the city you have to count 10 liters. Larger, elevated and extended versions, a bit more.
If the mileage really is 220kkm, then you still have a lot of driving ahead of you without major problems. Something will always pop up there, because the car is old, but it will be crap.
