Coolant Leak - Interior

[WelshPetrolhead]

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

I see your name is already showing Green, meaning you now have full member access status.

Understand your reluctance, but yes

Took the car out for a run to get it up to temperature, started to get a whiff of coolant.

That figures. The balance valve probably works then

I found this thread from the last owner, but is not really clear what has been done:

If it transpires that the problem looks like more than a leaking hose joint, try and call Dom to ask which, if not both, of the valves have indeed been changed, and how. I'm assuming that the Two-Sixties valve has been fitted, or waiting to be fitted, as intended in the plenum (main Hot/Cold valve) and the other DMGRS one is the one now leaking, modified and operating as a replacement Balance valve.

Thanks David!

I contacted Dom who clarified that the foot well balance valve was replaced with the DMGRS plenum item, that was done in January 2021. The club valve is waiting to go into the plenum.

It's raining now, so will have another investigate when its dry, and see if I can tend to the suspect hose. Will also check the condition of the plenum valve.

That's positive. Could still be a leaky balance valve of course, but probably just the hose connection. Usure about the expected lifespan of the DMGR units. If the heating and airco appears to be behaving, I would leave the plenum valve switch, at least for now. They are good, but can be tricky to set up.

Yeah the heating/aircon appears to be functioning okay. It's just the coolant smell. Will look at the hoses ASAP and then go from there.
