Possibly some issues with the maximum achievable speed, please investigate.
- Fuel filter clogged.
- Fuel lines are leaking, and air is being drawn into the fuel injection pump.
- Mass airflow sensor defective, verschandeln with brake cleaner or replace. See: /viewtopic.php?t=3347 and /viewtopic.php?t=26548
- Solenoid valve for turbocharger boost control/boost pressure.
- Vacuum hoses and vacuum connections for the VTG (Variable Turbine Geometry) adjustment or wastegate control.
- Exhaust gas recirculation (EGR), valve, and solenoid valve for control.
