Srs airbag fault on 270cdi

Hello everyone. I’m having a problem with SRS malfunction and don’t know how to proceed. Everything started when I was replacing the turn signal switch (have bought a new one from dealership). After replacing it an SRS airbag error occured. After diagnosing with STAR it said that there’s too high resistance in driver’s airbag green pin. I’ve tried to put another airbag, but still was unable to delete the fault. Then i’ve changed the SRS clockspring together with steering angle sensor to the working ones. Successfully the fault was erased but not for too long. The next day it popped out once again and the diagnosis was saying the same type of error. Then i went to a local electric who looked at the schemes and recommended to put resistors on the pins of the clockspring, in this case only the wheel buttons and the horn was connected with the black cable, while airbag wasn’t. So after doing that the fault was erased. Until the next day when the same type of error occured... and it always occurs when i turn the turn signal to the left! Don’t really know how to deal with it. Any ideas?

What happens when you install your old turn signal switch?

I haven’t tried that because it wasn’t working at all so basically I’ve just thrown it away.
