Ford Mondeo: Dual-mass flywheel failure on TDCi manual transmission

Manual TDCi Mondeos use a dual-mass flywheel (DMF) to dampen diesel vibration, which wears between 100,000 and 180,000 km. A worn DMF produces a rattling sound when the clutch is depressed, harsh vibration at idle in gear, and clutch judder on take-up. The DMF is replaced together with the clutch kit as a package, making it a significant repair. This is one of the most consistently documented failure modes for manual TDCi Mondeos across owner forums in both the UK and AU markets.

• Rattling or rumbling when the clutch pedal is fully depressed
• Vibration through the gearstick and floorpan at idle with the car in gear
• Judder on clutch take-up from rest
• Clunking noise when moving off slowly in first gear

1. 1

   With the engine idling in neutral, depress the clutch and listen for a rattle or rumble that disappears when the pedal is released.

2. 2

   Rock the car forward and backward in gear with the clutch partially engaged to feel for judder.

3. 3

   Request clutch replacement records.

≈A$1,470 to ≈A$2,940 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the clutch or flywheel been replaced?”
• “Any rattling noise when pressing the clutch pedal?”
• “Do you notice vibration at idle when the car is sitting in gear?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
