D38 on the french forum had the bolt/cover smash problem on his march 2014 after just 3500km.so 2014 are not safe.True,no lasting damage,but a disaster if you're on a trip & miles from a dealer.It should'nt happen..why is the bolt threaded in such a direction,as to allow the it to come undone on the rotation of the pulley?I repeat,there should be a recall of all MTWs to have the new kit fitted
