Hi all. My flywheel has started rattling and making noise a while ago and i decided to change it over the weekend. Been told first that i have got an SMF and given only the clutch to change. Once we took the gearbox off we realised its a DMF. Went and bought the DMF,installed it and everything was fine. The car run better than before. But,as soon as i got home and stopped the car the car won't start again. It will only start when the engine is cold. I am now looking to get the SMF conversion kit from Darkside Developments as i have seen on this forum that someone else had the same issue before. If the DMF we installed on the car would be the wrong part,is it normal for the car to run and then not start when the engine is cold? Has anyone encountered this problem before? Should i be looking at a different problem with the car? My mechanic has done a few diagnostics and nothing comes up,no loss of power during driving or any other symptoms. Thanks in advance.
