Litronic bracket woes and headlamp adjustment errors

I have a Cayman R with GT3 arms and 6mm shims. These were put on by the first owner many years ago (2015). Apprently back then either they didn't make the Litronic shim bracket or this guy just forgot to buy it, but anyways the shop that installed it simply zipped tied the old bracket to the arm and apparently that worked for a while. I had the car in the air replacing the PS return lines that were leaking and noticed that the zip ties were loose but didn't touch it. After getting the car back on the ground it started throwing Headlamp adjustment failure warnings as soon as I'd start the car and buckle in. Mind you, I drove this car 1400mi across the country and it never once threw this error. So I got the car back up on the lift and removed the old loose zip ties, held the bracket in place and installed new zip ties tight so the bracket doesnt move. Now when I get in the car the code doesn't come on when I start the car, but after I've gone down the road a bit, sorta random. Also it will go OFF if I articulate the suspension, such as taking a sharp right that loads that corner, or go up a steep drive at an angle which takes load off the LF corner. My questions are this, short of trying to source a bracket for a set of arms of unknown origin (seems each brand has a different Litronic bracket design), is there some sort of calibration procedure for the Litronic sensor? I feel like it doesn't know its limits anymore and is erroring out when it is loaded and going off when it is not. Also, with no errors in the car in my garage if I turn on the low beams and switch to high are the lights supposed to dip? I don't see it against the garage wall, or maybe it is just really subtle.

If what I’m reading here is correct, you say the previous owner did this work in 2015, which would imply your car is not a 987, meaning this is the wrong forum. Correct me if I’m wrong.

Every Cayman R was a 987.2 . I’m still not quite sure what is referring to though and I cringed when I read that somebody repaired a Cayman R in with zip ties.

I'm correcting you, as you are wrong. The WORK was done in 2015. The car wasn't built in 2015.

There are no mounting points for stock brackets on aftermarket GT3 arms, this is why they sell Litronic brackets, but this person didnt get them. Apparently the shop thought it was fine to zip to a plastic bracket to a piece of metal. And apparently it worked for years.

I’ve seen a lot of repairs in my life that were effective that I would never render on my own vehicles. Please understand I fully recognize you are not responsible for this situation. It’s just my comment in general terms. Additionally, I see it as sort of a shame because the Cayman R was already specially prepared by Porsche . It’s hard for me to believe that the addition of these parts were more important than the previous owner improving his driving skills if he desired better performance.

Thank you for your helpful insight. So far Porsche ownership is living up to all the things I heard about it.
