Are the nipples used in the AUA & BBY applications? Or just the flat section for clearance?I've just checked on 7zap, and it turns out that the 1.6 BAD FSI death pipe is exactly the same part number for the 1.4 AUA and BBY engines. That part number is 032 121 065 D so this part would be useful for those engines too, and may help to increase the order quantity. See here:
Cooling System - BAD engine
Cooling System - AUA and BBY engines
I recently changed this pipe and thermostat housing on our AUA 1.4, and the end of it where it goes into the water pump housing was falling to bits (possibly not surprising after 155K Miles and 23 years of service).
The flat bit on this pipe is necessary on the AUA and BBY engines, because it passes between the crankcase breather oil separator and the engine block. This probably keeps it warm, and may prevent condensation in the separator? On these engines, you have to take off the oil separator to change the pipe.
When I changed mine for a new Audi one, I would have definitely gone for one of these instead if it had been available. So in summary, I just wanted to say that the weird shape actually makes it applicable to a lot more applications.
On another note, the O-ring seal at the water pump end of this pipe is available separately, under part number 032 121 665 A.
