Request for Circuit Diagrams for Control Units

Hello everyone,
I’m in urgent need of circuit diagrams for the following control units:

• 23173664 / 6pz 011.275-21
  
• 23173663 / 6pz 011.275-01
  

These are lane-change control units that unfortunately came into contact with salt due to poor sealing. As a result, I need to replace some capacitors and resistors. To do this correctly, I require a detailed circuit diagram of the boards showing the specific resistors and other components.
If anyone has access to these diagrams or knows where I could find them, I would greatly appreciate your help!
Thank you in advance for your assistance!
