Recently my abs started to alarm regularly. Recently, this alarm is continuously present as soon as I start driving.

I measured my sensors and they turned out to be OK. All around 1000 ohms. Even so, I replaced them 1 by 1 with a good one. Except 1 (right rear) that was completely stuck.

I replaced the G20 relais

Then I replaced the ABS module with a good one. No difference.

Now I have also replaced the ABS pump with relays. Comes from a parts car. Not quite sure if donor part is okay, but looks better than the original one.

Now I don't know what to do anymore.

Does anyone have an idea what the problem might be?

(Apart from that one sensor, I replaced everything. I don't suspect the sensor as the ohmic resistance was good.)

Thanks in advance.

Problem solved. I cleaned everything with compresserd air. If only I had done that first.
