Hi all, my mother inlaw has a 2.3 diesel Serena which is making a hissing noise when revved. Somebody has told her that it needs a new turbocharger. I have looked at the car myself and cannot see any turbocharger at all !. The exhaust seems to be leaking from the front flexi pipe which i think explains the noise. She is still convinced that a replacement turbo is needed. Could sombody tell me if the car is turbocharged and i am missing something.

Many thanks, Graham
