Hi thanks for havin me .ive being getting a 2005 ducato 2.3 motorhome a couple of weeks ago.drove it from Preston to Carlisle and was fine apart from a sound or gushing air in 1st two 4th gear and what I think a bit guttles in 5th gear.there seems to be a little bigger t of smoke when I put my foot down.is this normal or have I a problem(hope not). It's done 21000 miles.thanks for your time of reading this
