are separate (two components): part numbers 8K0906253 and 8K0906253B supersede to 8K0906253D.
• For vehicles with a fuel tank pressure sensor, G400, and a fuel tank leak detection control module, J909, which
are integrated (one component): part numbers 8K0906253A and 8K0906253C supersede to 8K0906253E.
