I had a similar problem since i got my megane. Mine's 07. When engine rev to 4000rpm for 10 sec, engine check amber light flashes...if continue to drive, check injection msg with a loud knock, then power loss. Re-start, everything is ok. Brought back to dealer, replace fuel injection unit and now ok. But i have another problem now...extreme high fuel consumption after the new injector. Dealer said drive for a few weeks..may improve..still testing out.
