ABS Error Codes 00290 & 00287 - Ibiza 1999

I'm not a VW fanatic myself, but I have some friends who are. The Ibiza in question produced these error codes. Sometimes the ABS light stays off for several days, and other times it comes on immediately. One of my best friends currently has a diagnostic tool, and he's more familiar with Japanese cars. Where should we start looking for the problem?

With the Autoscan ???

I don't currently have access to the diagnostic system that we purchased and used together. My friends performed the data retrieval, and I wasn't present. I will only pass it on if that is a condition.

Hello hat riders,
It's not about the condition, but we need the data.

Okay, hier ist die Übersetzung:

"PS: And if possible, please indicate how the errors occurred. Were they sudden, or did they appear after a repair?"

The vehicle is usually located far from its home base during the week and only comes within range on weekends.

Nothing has been done to the brakes so far. In the past, the ABS light has reportedly come on sporadically, causing the ABS to stop working (brake test on sand). However, it didn't come on often enough for people to pay much attention to it. In fact, it was often working normally for weeks. Since the beginning of the month, the problem has intensified, but there have still been days when no error was displayed. However, the periods with the ABS light on are now becoming more frequent.

Given the upcoming vehicle inspection, something needs to be done, but it shouldn't be a random replacement of parts in the hope that something will work by chance.

Possible causes include:

- Cable break.
- Sensor
- SG/Pump


I'm curious to see the log and which error is documented.
