Replacement for module on board

@trustautomation what module, what car? Make, model and year of the car? Where is the module located? What does it look like? Post pictures of those "modules" with your Question. Adding images to an existing question That way we can see what you see and hopefully can help you find these.

The Siemens numbers you are listing are simple relays. The trouble you are running into is that VKP-31F32-Z01 were replaced by VKP-31F72-Z03. However the entire VKP series has now been discontinued and is obsolete.

Now, if you use your car's exact year make and model and search for headlight relay, you should find the right relay.
