Took three trips to shop to complete 30,000 km check, oil / filter changes etc. Had to return for second visit to replace pinion seal (need noted by technicians, done under warranty), third visit to replace faulty NOX sensor (warranty) that was on back order from Germany. NOX replacement was complicated by RV conversion water tank blocking normal access to NOX - Service Mgr suggest there would be extra charge for additional labour time but in end did - no-charge.
It was a bit disappointing to need three visits but overall I was pleased with how I was treated.
There were three other Sprinters in the shop yesterday at least two from businesses that have a number of Sprinters.
