My 2008 Dodge Ram 3500, 6.7 Turbo Diesel was plagued with code 0340…sticking turbo vanes. All remedies pointed to turbo removal. After a gallon of Lucas Fuel Treatment the code has cleared and all turbo and exhaust brake function has returned to normal saving me at least $1500 to $2,000. Thank you Lucus! If only more Dodge owners knew.
