the aaz engine has no intercooler and the ahu engine does - difference is more power and improved mpg apparently.

The block is basically the same and interchangeable, aside from the pistons.

Are there any TDI's with a mechanical fuel system from the factory (other than something like the electronics on the AAZ)?

Not in N. America but I think there were a few in Europe.

ALL TDIs have electronics. The 1.9 AAZ was the last TD (IDI) engine and it has no electronics at all.
