I took out my cat out of my car an now the engine light is on and vag-com is reading that its bad or a sensor is not working, does anyone know how i can fool the ECU into thinking the cat is installed and working properly?

yeah i think you car, i think you can get a spacer which fits in between your 2nd lambda sensor and the pipe, search for it,

in turn this then reads slightly less emmisions making the ecu think the cats there :)
hope this helps
