Hi all been having a few problems lately with the hippo it's been to 4 garages now 1 said turbo 1 said something about crank censor the other 2 admitted they didn't have a clue now the symptoms are when it's hot and you are trying to accerate there is a clicking sound it's very metalic sounding and black smoke let off a little sound goes and so does the smoke the sound is like a football rattle and all so I don't know if it's conected but when you turn it off and leave for around an hour it fires up first time but sluggish and lumpy as he'll no fault codes and no lights on the dash it's a td4 just wondered what your thoughts were before I have to get rid many thanks
