i changed a rear light bulb on my golf on sunday and the holders come out fine if you take the wiring plug off first and then unclip the holder. then just slides out. I did pull the carpet back to give more access.
What i would like to know though is i only have a fog light working on the drivers side but there is a bulb on the passenger side where the fog light would be but it doesnt work.
Do golfs only have 1 fog light at the rear? if not then may have a problem as i tried another bulb and it still didnt work.
