Popped a cheeky California Scent tin under the passenger seat in the mk4. Mmmmmmmm. Nice!
My bro's mk3 1.8GL failed its MOT on just about everything:
No front side lights?
No ABS light - turned out the dash panel was un-plugged (?) Plugged back in and OK now
Wrong colour reflectors on the "CE approved" rear clusters I bought him
Rust near one of the seat-belt points...
Failed emissions - high CO at fast idle ? Max was 0.5% and he scored 0.6% or something. I recommended he change the air filter and oil+filter and thrash a tank of redex through it then get a re-test.
