The repair estimate of $1800 was based on 8 1/2 hrs labor I believe. The SA was willing to cut me a break and offered a repair quote of $1300 before he went and lobbied for "goodwill" repair.
The angle of my approach was to convince the dealership that this malfunction was emissions related. The emissions system has an 8yr/80,000 mile warranty. Valvetronic is not considered to be within the scope of the emissions system.
You have to agree that this seems like a rare failure.
