Disadvantages of the B5244S engine
- Most complaints were about the version with a buggy electric choke Magneti Marelli.
- Another well-known engine problem is oil leakage from the phase regulator.
- The timing belt is designed for 120,000 km, but it can burst earlier and the valves will bend.
- Often the crankcase ventilation system is clogged here and lubricant consumption appears.
- The weak points of this engine also include its supports, thermostat, pump and fuel pump.
