While I am under warranty still in some aspects, last trip I left everything in the truck. The "head" diesel guy and myself had a discussion about this and that, and this particular dealer will attempt to warranty a VP44, but if Bosch rejects it you must foot the bill. Some go through some don't. What surprised me was when he said it was only around $1700 (including labor). Key thing with this dealer is be honest and upfront about it.
