Disadvantages of the Saab B284L engine
- The most famous problem of this engine is the low resource of timing chains;
- The electrician delivers a lot of trouble, most often the ECU and the oil pressure sensor fail;
- Overheating often occurs with breakdown of gaskets due to a jammed thermostat;
- The turbine runs normally, often only the bypass damper or bypass fails;
- The weak points of the power unit include ignition coils, as well as a gasoline pump.
