I only have 5 buttons: recirculate, aircon, heated rear window, auto, and off. Off lights up when pressed but as far as I can tell stops all airflow. From what I've read the auxiliary heater would be on I drive and it doesn't show there. Therefore guessing I must have single barrel valve. There are a few useful pics of these on ebay with hoses attached. The mounting is very different to the double barreled so location is possibly different hence my not being able to see it. Clamping would also give a clear indication of whether it ihas failed so probably my next step when I've found the thing!

Do you have 2 water pumps on you car? If so the smaller pump is for Aux heat.

I'm guessing I have 'basis' but both diagrams show parts avilable for my car. Basis has a single barreled pump with only two hoses. 'High' has double barreled with three hoses. That's for models with 'Auxilary' How do I tell if I have 'auxilary'?

So, any possibility of clamping/ blocking one of these hoses until I get around to doing the job? Guess no problem on 'basis' as it would have same effect as closing valve.

Yours is the first configuration 1493., you can tell by the item number ten being greyed, and on 1491, the notation at bottom in red.
