This is a Euro 300D (W124) with the NA 603. The belt was changed ~ 1000 miles ago when it partially shredded enroute to Maine. The shop who did the "emergency repair" said everything was lining up and the tensioner looked fine.
Looking at my belt today, I noticed some shavings on the side. I can also see a very faint line on one side developing. Is this normal or should I be concerned?
