    R129 duo valve/coolant circulation pump

    Okay so coolant leak from this area, stupid place to put them under the brake servo, can't see properly or work easily down there. I suspected the duo valve, I've had the thing apart in the past, to clean it up when jammed. However I can't see any obvious leak, the coolant circulator...

    S320 (W220) Duo Valve easy to fit?

    I believe my Duo Valve is faulty as there is very little heating although cooling is fine. If I were to find a used one can they be fitted fairly easily or do they need to be programmed to the car like an alarm module etc. Any ideas of a good place to get one from? S320 2004...

    W210 duo valve

    Olly having done my evaporator, the air-con is now delightful. However, one problem remains. In a seemingly random way the right hand side vents (driver's) would start blowing hot air without any regard for the dialled in temperature, which was always warmer than the left anyway. Olly...
