Hi everyone I have a bit of a problem with my 2006 Peugeot 407 2.0l hdi when the engine is on it makes a loud popping noise when the bonnet is opened the noise appears to be coming from the middle of the engine and sounds like its underneath the block I suspect maybe a blockage some where but I'm not sure has anyone else had this problem with their car and if so how do I fix it. Any sugestions please would be very help full.

Difficult to assess a noise without hearing it,but could be combustion loss from a leaking injector seal.

A Planet / Diagbox diagnostic should tell you if there's anything wrong with the injectors and their flow.
