Is this a UniAir/MultiAir engine?

I have no knowledge of this engine in your car but to have the symptoms of no compression at all suggests that if the engine is a UniAir/MultiAir unit then the hydraulic driven intake valves my be no functioning correctly and the system needs bleeding or other attention.

The engine code is 55282151 120 bhp , it is the hydrologic valve unit engine
