ABS stopped communicating with ECU

[Danny_OCT1]

Hello. I want to apologize in advance, for creating a new topic.

So. I bought skoda octavia 1.9 TDi 74 kW 4x4 as a project, lots of things got done, but every fault has been fixed. Everithing was working fine, but all of the sudden ABS stops communicating with ECU and can not be red with VAG, every time front wheel slips. ABS light comes on and handbrake symbol starts blinking and ABS stops responding to anything. I checked if canbus has the right rezistance, Yes, it does, and I just can't figure out what's wrong with it. I was looking everywhere, but I just can't find anyone with same problem. Please. That car's starting to really **** me off, so... If anyone knows anything that could help, just say it. Any idea, could be a usefull idea.
