Advice needed with problems

[MattGalaxy]

Hi,

Happy  Christmas all!

We own 2 Ford Galaxy's both with some problems and your advice would be great.

2008 2.0 tdci ghia

Lacking in hot air in cabin and reduced blower power compared with our other galaxy. Metal pipes under dash seem to get hot.

Car has recently had new thermostat, cambelt and water pump. 

Hissing sound from brake pedal, stops when pedal pressed. Car seems to run fine. I'm thinking the brake servo is bleeding atmospheric air through control valve to vacuum side? 

2006 2.0 tdci ghia

Engine fault dash warning: garage suspects glow plug issue but says they've tested plugs and relay and they work fine. Car drives but won't rev past 2k and have been using like this for a few months. High pressure fuel solenoid? Other component in glow plug system?

 

Any help would be great thanks. Any one local who wants to come and help? 

Thanks, Matt.
