CPO will probably cover it unless you have modified your suspension. If you have then most likely it won't be covered.

Thanks for posting this. Following this procedure, I confirmed that my PDSL lights are operating fine.

FWIW - Earlier this year I had a "PDLS Failure - visit workshop" error that was cleared by my Indy. I was concerned that while the error message was gone, my light were not "dynamic". Apparently not the case.

My 2007 997.1 has the same problem too, I am finding what is the problem behind.

Wanted to revive this thread as I had he same issue when I lowered my car. I found that I broke the same bracket pictured above, but on the front. I had no idea it was so important when it broke so I just ignored it. The bracket is attached to the trailing arm and connects to the leveling sensor via a little tie rod looking thing.

I JB Welded mine back together and my error went away. We will see if the JB Weld holds, lol.

This is the whole assembly.

When I installed my RSS suspension bits, the used set of LCAs I bought didn't come with their bracket. I just made one out of aluminum angle iron, which also let me bend it a little to fine tune the level of the lights that's maintained.

My headlights are not self-leveling (tried the test), but I'm not getting an fault. The front leveling arm was broken when I bought the car, which I have since replaced. Is it possible that a PO reprogrammed the car to turn this feature off instead of fixing the issues?
