This morning I set the brakes to get it into gear. The brake pedal popped ten settled a bit then it took both feet to hold car in place. I can hear a subtil SHHTTTPPP vacuum like sound from inside the car with TDI running when ever I touch the brakes.

Now...what would be the first (or second) think I should look at to fix this.

Looking to buy.
Check your vacuum lines, the brake booster works from artificial vacuum created by a vacuum pump. It sucks on the brake diaphragm to help you not have to press so hard on the brakes to stop the car.

A bad vacuum booster makes a noise like that. Get a second (live) opinion.

(sig Q) He could chuck quite a lot of wood..... but shouldn't we be asking how far can he chuck it and are we standing a bit too close??

I suggest you look at the brake booster hose, they are know to fail and cause hard pedal.
Runs form the master cylinder to the vacuum pump.

Took a look at some of the hoses. The hose coming off the side of tandem pump closest to engine seem to be loose, can rotate around the axis. Also there is a side to side motion as well. This rubber tube goes to a piece of curve angle plastic tubing. Loose to me doesn't seem good.

What do you folks think

Okay...
This VW shop here locally (not a dealer) found that the tandem pump failed. This was the recall tandem put on about five years ago. Do these routinely fail in your experiences? Fool thing costed nearly 400 dollars.
