I'm no expert .. but if memory serves me, HBV leaks can occur at odd times depending on heater demand...
Basically the HBV diverts water through the heater matrix to provide heat in the cabin, the leak can vary with the heater demand.. so it can be difficult to actually "see" the leak
:(

i do seem to lose more water with the heater running, i noticed that the other day when i checked.
thanks

Personally I would say, do the HBV, see if it solves the issue...then see where we are then?? Check the pipes going into the HBV too for cracks as this is common I believe...

i did also notice that the other night after doing 30 miles when i stopped i could see steam coming out both sides of bonnet but by the time i got it up it was gone and too dark to see anything.

Please excuse me for showing my ignorance but what is a 'hbv'? Lizzie Zoom :o

Lizzie ..... HBV = Heater Bypass Valve
As I said ^^^ it controls the amount of hot water going to the heater matrix... more when you want warm air, less to none when you want cold air ...
All rubber construction, vaccuum controlled and prone to splitting .. some have big splits that leak like b*****s .. others have small leaks that only appear at certain settings so are difficult to trace.
It is right at the back of the V6 engine and folks like me with big hands will a) get cut to ribbons b) put a lot of money in the swear box when changing one .. !! :)

Heater By Pass valve. Lives at the back of the driver's side of the V Look for something that looks like a Star Ship Enterprise ;)

Steam could be the water dripping onto the exhaust...soon as you stop the car to look the pressure may well have dropped resulting in no leakage and so cant see where its coming from...or was the engine still running when you got out to look? Sounding very much like HBV area...I have one here thats ok but for the money they cost new you may as well get one from Vaux...
