While on the way for our FIRST weekend in our NEW 2552 (the "Toaster"), I noticed the "check engine" light was on (solid, not flashing). Less than 1200* miles on it. Pulled over, did some quick research, checked the gas cap (it was tight) and finally continued on our way. All the info I could find indicated that, if the engine was performing properly it was safe to continue until we could get it checked. The campground is 28 miles from our home. Got home Sunday no problem and first thing Monday I called the local Ford dealer (less than 10 miles away), told the story, and was told "we don't work on RV's". Called the next closest dealership (about 20 miles away), they asked the wheelbase length then replied "that's just over out limit." Called the next closest dealership (30 miles away), they "only have one lift that can handle something that big and it's occupied right now" so they could not help.
On the advice of an acquaintance I drove the rig to the local Advance Auto and the nice fellow there (Jay) determined the error code was "P0496" which is "an issue with the purge flow in the EVAP system. Apparently the engine was not handling emissions safely as designed. I next called the AWESOME folks at Capital Ford in Charlotte (40 miles from home) and made a service appointment in the Heavy Truck Center. They diagnosed a "purge valve was stuck" and replaced it, under warranty of course, and all is well. Paul at the desk there was outstanding to deal with and we had our beloved Toaster home in the same day.
It bothers me that none of the first service centers I called even offered to try and diagnose the issue, even if not equipped to fix it themselves. Perhaps they might have helped me find the nearest dealer that could help. They could have done better than "we don't work on RV's" or "our lift is tied up" - each time I explained clearly that we have a new E-450 under warranty. All is well now, but we have looked up the Ford corporate customer service number and plan to give them a call.
*About the 1200 miles - the coach had 950 miles when we drove it home, I assume having been driven from Indiana to Raleigh NC. We drove it 160 miles home from Raleigh.
