Thanks Guys for your help so far. Nich, I've had the questionnaire and sent it back to Tim. I'm just waiting on my MGOC number as I've done that today too.

Luckily it was a dry morning so I got out, removed the panel under the steering wheel to get a better look. I mopped up what I could get to with some tissue to dry it. Tried jiggling that hose inwards but its going nowhere...Is it just a case of pinching the clip to loosen, push hose on more and release the clip?? I'm wary of disturbing anything at the moment.

Took the car out for a run to get it up to temperature, started to get a whiff of coolant. I then changed the settings on the climate (which was set to auto), up to 23 degrees, and the dashboard/face vents. Interestingly the coolant smell faded. Got the car back on the drive, left it running and got into the footwell to have a look and its the same as after I cleaned it up. I will check the car later once it is fully cold, to see if there is any change to the footwell area but also check the coolant level.

As a side note, the car has the DMGRS plenum valve fitted, I have an invoice for both the part itself, and another for fitting it, and even the old part in a box... The car came with a box of bits and I have what I assume is the club 3 way valve (The box it was in has Tim's name and address on it!) The actuator on top has a Bosch VW/Audi label. I thought that this was a spare for the plenum valve or an upgrade over the DMGRS one. I will check out the thread above, but could this be used for the interior valve?

I've taken a few pics of the area, the valve doesn't look terrible from what I can see, so perhaps its a minor weep. The new assumed club valve is in pic 5
