The weak point of this motor are the valves and couplings of the phase control system.
Ford QXWA/QXWB
On engines of the first years of production, the chain between the camshafts was often stretched.
Ford QYWA
The main problems for the owners are delivered by the capricious Common Rail Delphi system.
Ford SEWA
The most common engine failures are the ignition system components and the fuel pump.
Ford 2.2 TDCi
The main problems of this unit are typical for most modern diesel engines: piezo injectors do not tolerate bad fuel, the EGR…
Ford KNWA
Sophisticated fuel equipment with piezo injectors does not like bad fuel.
Ford TPWA
Direct injection system components often fail due to poor fuel.
