Heaters constantly on hot!

I don't know if this is the right section to be asking about the heaters but here goes…
Basically they are blowing hot all the time. Can i repair something or should i just get new parts? If so what bits do I need to change?

if you look to the left of your brake sevo ther are 2 pipes that come out of your bulkhead and 1 of them has a valve on it that opens and closes changing the temp, this has a cable from the dash to do so, it may have come off but you can move it by hand very easly

almost certanly in the heater control valve as indicated by the post above.  Easy to check - remove valve (two jubilee clamps) and attach to a garden hose - conveniently the valve inlet is exactly the right size to fit onto a hose.  Turn hose on and open the valve - water flows - close valve and the pressure should be sufficient to blow the hose off - if water continues to flow - valve faulty and needs to be replaced - available from VAG or GSF - part number 171819809E

i just changed my heater valve  very easy  and cheep only 9 squid from gsf  drained out the water changed valve  very easy   so much differance how that helps

glad you got this sorted - when the rain stops - roof down!

well done
