Symptoms
Vibration or harshness at a steady 1,700–2,000 rpm on B57 diesel trucks.
The fix, step by step
- On a right-hand-drive diesel, one INEOS Forum owner found the 10 mm bolt holding the heat shield between the airbox and firewall loose.
- Tightening it removed about 90% of the harshness.
- Others traced rattles to an exhaust heat shield and to the heater pipes under the glovebox.
- These are owner fixes, not an Ineos bulletin.
