Non aircon 940 heater valve
Hi folks,
Really struggling with this one. I understand the part I need to be completely obsolete. So my problem is what now? Given no part exists I might as well have a go at repairing the leaky valve but I am unclear how to remove it from the bulkhead. I am working in the footwell not the engine. The plastic control box that holds the cables seems to have no obvious means of detaching it - and breaking it would be fatal! If of course I can't fix it and have to accept some other solution (meaning I will lose the heater control on the dash) what have others used? I considered a 240 RHD non aircon valve but am advised it is too large a diameter to fit. Someone else suggested a TX1 valve readily available on Ebay but they don't look anywhere near right. I am not keen to go to anything electric. I can live with pulling the cables under the footwell if I must. The leak is fairly slow. I did wonder if I can try a repair on the valve and then adding K-seal might do the job.

Vicky,
There are a number of .”how to’s” in this section if you do a search, including one from me, but in the mean time, remove the trim panel from under the facia, remove the clutch pedal from the bulkhead leaving the securing bolts loosely in position as they also retain the clutch slave cylinder. Disconnect the control cables from the valve. The valve is located in the bulkhead with a bayonet fitting (like a light bulb). Turn it through about 90 degrees and it should be free. I’ll try to find my right up about doing mine. I’ve just bumped a thread which may be useful to you. See “940 heater control valve”.

Thanks have already gotten in there. Tried to add a photo but it won't let me. Useful to know about bayonet fitment, I didn't want to start twisting lest I break something further! It's an auto so access is fairly clear.

I didn’t know it was an auto. I’m fairly sure that there are others in the forum who have knowledge of work arounds for this problem. When my valve needed doing many years ago I bypassed it for a while by joining the heater pipes in the engine compartment. It worked but the car was freezing.

If it gets to that I'm thinking a piece of domestic copper pipe with an isolating valve!

As someone else commented further up, bypassing in the engine bay leaves you with no heater at all, using your idea of an isolation valve makes more sense but i have heard Mk1 VW Golf heater valves are near identical. https://www.ebay.co.uk/itm/Heater-Co...5/311930885143 For the sake of less than a fiver it may well be worth a try!

If you need to go the Golf Mk1 route I have the fitting details that were given to me by ano person (whose name I can't now recall) some years ago.

If you check your other threads someone else did find it and posted a link to it but there is no photo and it says phone for stock levels.
