Default 03G145702F (2.0tdi 140bhp turbo) max boost?

Hi All

This is a GT1749VA turbo fitted to the 2.0tdi 140bhp Audi A4 b7 model

Does this have the same max boost capacity as the slightly older VA's as fitted to pd130 awx/avf B5.5 Passat's? So a safe 1.5bar?

To me it looks the same other than having an egt boss

Basically same yes. In lower rpm range you can boost up to 1.6-1.8bar for good torque. In upper rpm 1.5 is fine.
