Correct Tyre Pressure?

[Floob]

Hi,

I've tried both these sites which give me different results:
Tyre Pressures - Search for and find correct Tyre Pressure values for your car (37 Front / 34 Rear)
Tyre Pressure Search (36 Front / 33 Rear)

I have a 2010 Sport 140 Tdi - what do you think the correct pressure should be?
Are either of the above right?

Tag inside the drivers door should tell you.
