    Hi, just back from another weekend of trying out the systems on the new Chausson 718. Tried the Truma heating on diesel which worked fine but there was a constant knocking noise from the front of the van. Before I call the dealer just wanted to check if it's normal - hope not! We found generally on all different power settings that it takes a long time to get up to heat. Is this normal? Thanks all.

    We had eberspacher , the dosing pump made a clicking noise which was fairly muted. The pump had a rubber band under the clamp which it was mounted to the chassis with. Does yours have this rubber?
