My right rear light cluster has had a crack in it since I bought the car, and as I was getting some door lock parts from a breaker I took the chance to get a replacement light cluster in the same package. The light cluster cost me £30 from German Car Dismantlers and it was very straightforward to fit. Sorry, no pictures.
- remove the rubber gasket strip from the light and clean it up with soap and water to ensure a good seal
- replace the gasket on the light
- apply Gummi-Pflege to the gasket to help keep it flexible
- Unclip the carpet at the rear of the boot
- transfer the bulbs from the old light to the new one
- unclip the plastic clip from the wiring plug
- unplug the wire
- unscrew the 5 nuts
- pull off the boot basket from the area around the light
- remove old light, clean up bodywork with a damp cloth
- my new light only had 4 bolts installed so I removed one from the old light and installed it in the new one
- install new light, tighten 5 nuts
- plug in and replace the plastic clip
- replace carpet
