Seat Ibiza LWR: Too many connection errors

Hello everyone, I'm new here and wanted to see if anyone might be able to help me with something.
Unfortunately, I can't adjust the basic settings for the xenon headlights because I'm getting an error message (55 LWR) indicating too many communication errors. The connection is constantly being interrupted. Since I don't have a wiring diagram, I've already replaced the altitude sensor. Of course, the new one can't be coded because there are too many communication errors.
"Using a manual adjuster in the light switch, which I currently have on hand, I can regulate the headlight height and also measure the voltage at the actuators. With the original xenon headlight switches, I'm getting 2.89 volts at the actuators. I would be very grateful for your help." Here is the log file.

Hi,

Unfortunately, I can't adjust the basic settings of the xenon headlights because I'm getting an error message indicating "55 LWR," which means there are too many communication errors. The connection is constantly being interrupted.

The connection to the other control units is working, so I would check if the wiring to the LWR control unit is okay and that it hasn't been damaged by water ingress.

Best regards, Rainer.

Hello Rainer,

Thank you for the quick response.
The LWR control unit is integrated into the LWR sensor located on the rear axle, and that sensor has already been replaced.
To make sure I understand correctly, when you say "waterlogged," are you referring to a specific location that is experiencing water damage, or are you referring to a different control unit?
I also suspected the body control module, but without a wiring diagram, it's difficult to determine whether the body control module is related to the automatic headlight range adjustment.
"Thank you in advance."

Best regards, Daniel.

Hello Daniel,

If the body control module is functioning normally and is accessible, it is highly unlikely that it is related to the automatic headlight range adjustment problems.

If the LWR control unit is new, I would carefully inspect the connectors and cables leading to it.

Best regards, Rainer.

Hello Rainer,

Thank you for your help.
I will do that right away and report back.
I hope I can find some information regarding the pin assignments.
"The body control module is normally accessible, which is a bit strange because in position 0 on the light switch, all the lights turn on in this vehicle, even though daytime running lights (DRL) should only activate the low beams. Unfortunately, I haven't found anything to change this through coding." Was this done intentionally by Seat?

Best regards, Daniel.

Hi Daniel,

I have no idea what all the lights are supposed to illuminate on that Skoda when it comes to "daytime running lights." My Audi also has more lights on than I would personally prefer, but okay.

Regarding circuit diagrams and pin assignments:
You can find wiring diagrams and more for your car at Erwin (siehe Fehlerdatenbank) for Skoda.

Best regards, Rainer.
