07.5 CTD PU model..... loss of power, valves knocking loud ,have to put truck in neutral at stoplight, is this limp mode? just picked truck up ,engine light on again (once a week) dpf replaced a week ago these idiots at the stealership don't have a clue !!! truck is all stock and its been a three year nightmare currently message center says service needed, see dealership now, I have never seen this message before, only catalyst full. Anyone know what the truck is doing??? I would like to maybe have an insight if anyone has experianced this before... I'm tired of all the bullshit the stealership keeps trying to feed me... currently looking at all the delete mods but not convinced it will cure my truck from all its ills..... please advise. thank you for any help
