brakes problem

good day

my octavia mk1 2007 has a brake issue.

since i wanted to bleed my brake system i discovered that the rear left wheel doesn't get brake oil. i followed the line till the ABS and there ..... i discovered that the ABS doesn't give oil to this wheel but the other 3 wheels.

the ABS Disassembling didn't help me because i couldn't test the ABS ECU .

could the abs unit be blocked?

Please help me because i live in Egypt and the workshop wants to change the ABS unit for a lot of money.

when scanned ,no error codes.

thanks in advance
