I topped it up yesterday when I got the warning on the computer and twice today (roughly 2-3 litres total). As I drive up to my parking slot I can see a long trail of coolant left behind on the road. 

Whats the cause and whats the fix?

Cheers

When you look underneath where is it dripping down?

[Broomies Mate]

Investigate exactly where the coolant is leaking, and you'll have a much better idea of how to fix it.  Could be anything.... even something as small as a split hose.

Big loss is most likely the bypass valve....sudden spectacular loss, the helter skelter pipe from bypass valve to engine

I can see it dripping from something thats behind the engine oil sump (if that makes sense).

Will check the passenger footwell but dont think there is any water there, heaters work fine although I am finding it difficult selecting gears since this happened (probably unrelated and coincidental)

Bypass valve is favourite then.....

[SMD]

So new bypass valve...how much is one of those and can it be changed at the side of the road?

[Marks DTM Calib]

Best thing to do is look at it first, check for traces of water staining

twenty to thirty quid, maybe not even that, and yes it can be changed without the need for shelter!

Sounds like HBV mate - ~£30 from Vx - don't get pattern get genuine Vx.
Bit fiddly to get at and remove hoses/clips - best to remove scuttle and plenum to make life easy.  Altough I didn't remove skuttle last time I changed one.

remove the scuttle and the black support plate

I paid £36 for new genuine VX HBV valve. Only fit a genuine otherwise false economy!.

I am a novice mechanic but followed the excellent maintenance guide and it took about 2.5 hours. Most experieneced mechanics will change it in 30 minutes I guess.  Definitely remove the scuttle for better access to the HBV....and do be patient...and expect a few skinned knuckles....plasters to the ready !

Good luck.

Had to do mine a few weeks ago and my swearbox was full by the end.... Not a bad job with the help of the very good how to. As said it cost me £37 for a new one from the sellers.
