Hi.
Not all DMF's have springs in the driven plate TBH. I don't think the 1.2 has a DMF, the engine mounts are very flexible in this version and it has the feel of a solid flywheel as well.
I can see the reason with the TA, it has a cylinder firing on each turn of the flywheel whereas a 4 pot it's every half turn so to damp out vibration a heavy flywheel would be needed on the TA with its 2 pot engine, a DMF would be the answer but of course DMF's are not exactly light. At anything above tick over there would not normally be a problem. The thing is in days gone by with a 2 pot engine a solid flywheel would have been fine, the 2CV, Fiat 500 & 126 coped fine but the TA is capable of over 100bhp and lots of low speed torque so those pulses need to be damped out, a mere hydraulic clutch damper wont help, so Phils "damper" is a bit of a mystery.
