My 2013 Ducato maxi 3 litre motor, with automated manual transmission, makes a loud bump when starting - almost like the exhaust hitting the chassis or the motor itself hitting something - quite a heavy sound. The bump occurs as the motor fires and the starter disengages. It is most prominent when cold. Less so when warm. It has done this from "new". The vehicle sat unsold from mid 2013 to Feb 2015 with small trips to shows. It has only done 4000km since.
I have had the unit to a Fiat dealer a couple of times. Fiat suggested that it was a dual mass flywheel problem and the dealer replaced it. If anything, the noise when cold is now worse.
Fiat is arranging for a technician to examine the vehicle next week.
Has anyone had this problem and, if so, what was the cause and remedy. I would like as much info as possible before the Fiat man calls.
Thanks for any assistance.
