Maggus, gibt es doch inzwischen massig auf Ebay com, in die Suche eingeben, die wird w. nicht mehr anbieten: bmw heater valve repair kit
des weiteren gibt es chinesische Nachbauten der Heizungsventile fuer ca. 70 EURO
hab aber in einem U.K. Forum nichts gutes drueber gelesen, Stutzen ist nach kurzer Zeit abgebrochen. Ob das nun von dem einen Hersteller war, oder alle so sind, entzieht sich meiner Info. Kommentar:
Last Sunday afternoon I drove along to local supermarket where it was pointed out to me that liquid was pouring out of the car and visible from the nearside. After adding water and driving gently home I ended up taking my new heater valve out only to find that the 2 outlets to the heater were loose, in fact one fell out in my hand. So I take it all back, they look good but clearly there is a tolerance issue as they are supposed to be an interference fit in the main body with an o ring providing the seal. Not sure if I have been unlucky or not, but glad I did not embark on any long journeys.
My fix Sunday pm was to split both original and new valves and put the new solenoid/seals/shutoff valve onto the original BMW body. I have not had chance to do more than a few miles, but it is currently ok. When time allows I will get my local garage to pressure test system.So to anyone else who might be considering buying one of these, I would be a little careful. It is the two outlets. They are an interference fit onto the main body with an O ring to provide the seal. The aftermarket ones are not a strong enough interference fit, they could probably be made to work by using epoxy and gluing them in though, however I think my 'fix' using the original old BMW body and the aftermarket seals/valves is probably more than adequate.
Bei Zusatzwasserpumpen rate ich zum Kauf von Original, hab einige Bilder bekommen, original und Chinanachbau

So this aux water pump conveys 200 liter per hour less than the original BMW pump, which has 950 l/h. But the price of the original BMW pump is more than double.
Also the connecting plug is different from BMW as well as total dimensions, so has to be worked on.
