I did an oil an filter change on our 2014 TwinAir Trekking at the weekend and noticed that the side of the sump under the pulleys was coated in a fine mist of oil as was the undertray. I have given it a full degrease and nipped up the sump bolts which all had a small amount of slack in them. Couldn't work out where the oil is coming from, just wondered if there was a common issue?
