Dual Mass Flywheels, seem to be designed to fail.
Some can last 100 k miles, others fail in half that.
A lot of people replace the DMF at the same time as the clutch, and fit a single mass, or standard flywheel, and the clutch plate will be the type with the springs in, ie good old fashioned proven technology.
So why oh why have they introduced the DMF to so many cars?
Is it supposed to give a smoother gear change?
Put less stress on a gearbox already designed down to a price...:doh
Have we seen the end of vehicles achieving 300k miles, like the Nissan 2.7 td's can?
Is this designed in obsolescence? :doh
The labour costs involved in replacing timing belts and DMF's in say a car 8 years old with say 100 k miles on the clock must be prohibitive, as the cost can be greater than the car is worth.
What car would I replace my 18 1/2 year old Mav with?
I don't know yet, think I'll keep it another year, and wait and see.:lol
I'm not impressed with the latest offerings from Nissan, too much renault involvement.
Modern engines are lighter, warm up quicker, have a high power to weight ratio, more and more economical with less emissions, must be really cheap to manufacture, as mostly done my machine, BUT on going repair costs can be high. Having said that, even a slight bump at 4 mph will now write a car off, I doubt many new cars will get to be 18 1/2 years old like my Mav.:doh
Where would I go from here?:nenau
