Changing reverse light bulb 997.1

[lingus75]

I have tried to find the answer to this potentially very easy question, but can only seem to find instructions on fitting new units.

Do I remove just the middle phillips screw, or also the star shaped bolts top and bottom to remove rear light unit? I suspect the answer may be in the owners manual, but I don't have access to it till the weekend, and the warning light is annoying me! Also, the owners manuals online seem to be only Gen 2 and don't cover rear light bulb replacement as they're LED.

Is it just an easy bulb replacement like any other or are there any pitfalls I need to be aware off, like weak clips etc?

As you can tell DIY isn't my strong point!

Thanks.

Just the middle one, pull the light unit out backwards. Bulb is a P21. (according to drivers manual)
