CEL, Power loss, low MPG, Dealer suggests Clean Turbo 2 times in 6k miles
05 F350 6.0 Diesel, stock, 30K miles.. Twice in last 7k miles my CEL light has come on and I immediately notice a loss in power when pulling a trailer (small trailer, less than 5k lbs) and my MPG go down from an average of 14MPG to 10MPG or less while pulling the trailer or empty. Took it in the first time and dealer said they replaced some valve (donít remember what) and because of a tech bulletin they also cleaned the turbo.. Everything came back Ok and about 6K miles later the same thing happened. Took back to dealer and they said no problem just cleaned the turbo and everything is fine now. I havenít gotten it back yet but wanted to post here to see if others are having similar problems or have a possible solution. On the first go around I changed the fuel filters before taking to dealer to see if that was problem, It wasnít but they are now fresh. My warrantee expires in just a few months and if this is a problem I want to address it before the warrantee expires. It is also a pain in the rear to take this to the dealer so even though they have fixed it both times I want to find and address the root of the problem.
Any help or advice would be appreciated
