I guess VAG hasn't improved air filter access over the years then. My CIS injected VWs/Audi ranged from a pain (Mk1 Rabbit and Mk2 Jettas) to a nightmare (Audi 4000 and '90 Passat). The only one that was easy was my '91 Jetta Diesel. The others had the air filter mounted underneath the CIS injection's fuel distributor/air vane unit.
