I looked in the boot to find the sticker which states it is has an ASZ engine. I have done a EGR delete on the car......but I get the P0401 code when I scan the car. What could this be?

OBD II Code P0401

Insufficient EGR Flow

because you have removed the egr you will get a fault code for the egr

yeah basically youve removed the valve so it cant measure the flow through that part because youve stopped it. nothing to worry about just a annoying light but some companies can map the light out.
