So, had a drive about in the dark and the lights are a bit rubbish. In fact, when I look, its only the sidelights that work. Hmmm, not brilliant. Must be the bulbs non? Off i trot, buy four new bulbs, change the two faulty ones and ….. nothing. Bother.
Take the fuses out and check them. Nope, they’re good too. This is tiresome.
Finally, after lots more reading on various Porsche forums, it appears the lights witch itself is the problem. So, I shall have to order one, get an idea of how to fit it, and give it a bash. First proper bit of DIY on my car, I shall photograph as I go along as a reminder of what I did.
