Mk4 focus 1.0 125 Engine rattle


Recommended Posts

Hi guys

My 2018 MK4 focus 1.0 125 has developed a loud engine rattle/tapping at idle, it almost sounds like an old diesel engine 

The strange thing is that it completely goes once the clutch is fully pressed down

Anyone else had this issue or knows what the problem could be? 

Thanks,

The 1.0 ECOboost in the Focus MK4 does not have a dual mass flywheel.

The Focus MK4 1.0 ECOboost has the MX65 gearbox combined with a solid flywheel. The MX65 gearbox is a modular design that includes both 5-speed and 6-speed versions. The Focus MK4 1.0 ECOboost has the strongest available version of the MX65 gearbox that can handle a maximum torque of 215 Nm. The MX65 gearbox was developed primarily to reduce costs even further the MX65 gearboxes are combined with solid flywheels. The MX65 gearboxes replace both the old IB5 gearbox and the B6 gearboxes on lower powered engine types.

Can you hear it from outside the cabin? My noise was louder on the left hand side which helped them diagnose it as a gearbox fault

 

Is it a constant noise or can you make it go away by putting the car ij gear / pressing the clutch

Thats completely normal if it sounds like its on 2 cylinders, these new fords have cylinder de activation technology to try save fuel
