Sorry no idea on the N75.. the older 1Z/AHU like I have had no such thing until the ALH.
It is likely the timing is whacccccck.

There is a valve similar to the n75 valve on the ahu but it has nothing to do with the egr. But, there is an egr solenoid that is basically the same in design. The only real way of deleting the egr without causing a fault is to have the egr deleted by remapping the computer.

temp sensors changed from 1.9TD to 19TDI I believe. My TDI one was a 4 prong plug..

I' don't remember exactly if the temp gauge work with the AHU sensor, but the RPM will not if you pick it from the ECU. You need an AHU cluster or reflash the little chip in your AAZ cluster with an AHU cluster files. I can give you the files if you can or have someone to do it.
In the case you want to trouble shoot, I have the current flow diagram for those cluster.

If you can get it scanned, you'll have your answer or at least a direction to go in. It might be your maf but without scanning it it's just a guess. It could be your map as well. Did I read somewhere that you don't have an obd2 port?

No i do not have an obd port. I bought one but have to splice it in... Also i must add that there is no smoke at all.

Make it a priority to hook up that obd port. There's very few wires including a power and ground and once hooked up you can retrieve codes with any obd2 code reader. Someone correct me if I'm wrong but I remember only three wires on the VW side of the obd port needed. Power, ground, signal.

Wired up obd port and didnt work.. So i went back and rewired it agian and havent been able to use an obd scanner yet agian.. Also i just replaced the maf and that didnt really seem to change to much really.. Soo next thing is to change fuel filter.. Also could a muffler cause problems? Or is there no way that could happen? Running out of ideas on what it could be..

You need to breakout a multimeter and make certain you have all of the connections put together for the diagnostics.

What are you using to scan it with? Not all readers can handle VWs. My cheapo unit couldn't anyways.

all the maf does is operate the egr anyways...

The MAF does a little more than operate the EGR I have two that were accidentally damaged in different manners and they both screwed up different things. Once caused crazy boost pressures and the other cause the car to smoke like a coal train with other drive ability issues.
