Ford Focus · frequently asked questions

Is the Mk4 Focus a safer buy than the Mk3?

Yes on gearboxes, but the wet belt replaces PowerShift as the main risk.

Which trim sells fastest?

ST-Line in petrol with a full service history.

What should I always check?

Belt paperwork. Without it, price the job in.

What is the difference between the 1.0 EcoBoost mHEV and the standard EcoBoost?

The mHEV mild-hybrid versions, introduced around 2020, replace the standard alternator with a belt-driven integrated starter generator and add a 48-volt battery to improve torque and economy. Crucially for dealers, these mHEV engines utilise a timing chain, completely bypassing the notorious wet belt failures found in earlier non-hybrid 1.0-litre variants.

How can I easily identify if a Mk4 diesel model is ULEZ compliant?

All Mk4 Focus diesel models, including the 1.5 and 2.0 EcoBlue engines, meet Euro 6d-TEMP or Euro 6d emissions standards. This means they are fully ULEZ and Clean Air Zone compliant across the UK. You can quickly verify this on the forecourt by locating the blue AdBlue filler neck next to the diesel cap.

Are there any specific exterior checks required for the Active trim level?

The Focus Active features a raised ride height and bespoke plastic body cladding. While mechanically identical to standard models, you must inspect the wheel arch and sill trims for loose clips, scuffs, or impact damage. Replacement factory cladding is expensive and frequently on backorder, which can severely impact your preparation costs and retail margin.
