I just converted my Polo 6N with AEF engine to a AFN 1.9TDI with mechanical Bosch pump.
Sorry for the crappy pictures. My digigital camera was broken and I took these with my telephone.
Inlet manifold with airtemp. sensor
You can see the small wheel through the cover. (I have to modify it)
I have to install the FMIC and break in the engine. For now low boost, small turbo.
I encountered some problems, but not for the pumpbracket conversion. The brackets from the 1900D 1X and the 1900TD AAZ/ABL are both ok to use.
You can use one from a TDI but that one has got the additional wheel for the belt. The metal plate to keep the cover in place and the cover it selve aren't suitable for the wheel. I modified them (make some pictures if you like)
