Disadvantages of the B5254T6 engine
- The main problem with this engine is the failure of the phase control system;
- Often there is lubricant consumption due to clogged crankcase ventilation or turbine shaft wear;
- All kinds of pipes often burst, especially the one that goes to the turbocharger;
- Change the timing belt more often than the scheduled 120,000 km, or if it breaks, the valves will bend;
- Other weak points: water pump, camshaft seals, fuel pump, engine mounts.
