Need to scan with VCDS, need more info than what you've given, too many variables.

98 Jetta TDI AHU 1.9L (944 TDI swap in progress) I moved so now i got nothing but an AHU in a garage on a pallet.
Ah, what?
so you defiantly should get a vagcom cable and run VCDS, but for the time being, go to autozone and scan the ECU for free, you will get some codes.

eBay, Amazon or good car parts store. £10-20, OBD II scan tool will tell you your codes and you can read live data and figure it out.
Glow plug symbol can mean multiple things.

Could you be more specific?

"if I rev to the limiter in every gear its fine", what do you mean by fine? It has power near the limiter?

What's the engine? Do you get any smoke? How's the DPF?

I would bet MAF, EGR ou DPF.
