Dear Porsche Enthousiasts!
We are new to this great forum! Greets from the Netherlands!
We have are having problems upgrading a 2013 991.1 TTS to a 991.2 TTS
The car has PDLS+ headlights, the new 991.2 headlights are also PDLS+ (attached pictures of the parts)
The electrical diagrams as far as we know are the same.
What ever we do, we get the error. ( No communication on left via (private) databus in system and No communication on right via (private) databus in system)
Can somebody help us in the right direction?

SOLUTION TO PROBLEM FOUND - PIWIS 3 with VAS clone interface has problems coding PDSL+ due to brandwith problems (found this on a Russian website).
Changed the interface for an original one with the same software. It was done within 2 minutes...

To an original PIWIS3 tester? ($6k tester?). Where did you find one of those?

curious: which VAS were you using that was bad?

i have a VAS 6154 with a physical USB cable but have heard issues with the wireless ones.
