Headlight problem
Hi,
I have a problem with my headlights. (Car is a 2024 Targa 4 GTS)
I replaced the headlights to new ones (ECE PDSL+) control modules are the same (once we tried but only the right one and it seemed functional), and now when I turn on the ignition, low beam turns on, and nothing else is working (no high beam, no daylight, no indicators) and the lamp cannot be turned off.
In the fault codes section I can see "SOA mismatch", and "invalid dataset" fault codes in the LED control modules (left and right).
Do you have any idea what I can do?
I have access only to offline PIWIS 4.
Thanks,
G

Did you *upgrade* to PDLS+ from base PDLS, or are you just replacing preexisting PDLS+ units due to crash damage or some other reason? If the former you will definitely need to recode the car with PIWIS to accept the upgraded equipment. If the latter they should drop in with no changes.

And I replaced them because of a crash.
