I have previously posted today regarding Ma depollution problem. Appears that hissing noise is a failed injector seal.

Basically has anyone had this and did it trigger the engine management light and depollution system fault on start up

Not had it myself but I would imagine that is why you are getting the fault and rough running as air will be getting drawn into the fuel system. De-pollution fault is generic and would imagine a diagnostic would show low fuel rail pressure.

Here's hoping. Was going to send it to get a fixed regeneration tha would have thrown money away glad I done my own detective work. Will get garage to fit new seals on injector and take it from there. Just hope that's is the cause of Ma problem.
