The usual...what to look for?

I know about the "gurggle" in the A/C and I pulled this off Carpoint:

"Occasional problems on this vehicle are failures of the Cylinder Head Gasket, the Engine Control Systems Unit (MAS Unit) and the Electro-Hydraulic Actuator (EHA). Failure of the MAS Unit will prevent the vehicle from starting"

Anyone have this problem or anything related?

Anything else?

Thanks!
