How to prevent dual mass flywheel problems Is there any way to avoid dual mass flywheel problems, other than by not buying a diesel? Are they affected by driving style or maintenance? I have a 2006 Ford Focus 2.0 TDCi and wonder whether I'm on borrowed time. Don't let the clutch out when you're in gear and the engine is idling - always apply some revs. Also, try to double declutch smoothly up and down the box. That's the advice offered by readers whose DMFs have lasted for 200,000 miles.
