A professional man said me that i had to replace the power steering pump. So i did. I found a second hand pump. The part fitted in my car was 6Q0 423 156G and the pump that i bought was part number 6Q0 423 156 M 

so I fitted new pump on my car but the wheel became very hard to turn. Can you tell me please  if i rated a state? 

the second question is; in VCDS i have faults codes about (G85) and (G250). I read on the web that there are not two sensors together in fabia. Is it?

Can you help me please? 

Thanks

There is one sensor, you must replace this, the sensor is in the steering rack under the car.

As Above the steering angle sensor located in the steering column when it meets the rack, part is about £100, two small tx bolts to remove but then a very long cable from it to the PAS pump with the old cable removed & fit the new one which is part of the sensor.

 

Part looks like this:-

Easy job, just tricky to route the wiring as all under the car... common fault/failure in these cars..

Thank you for your suggestions. I'll try to replace this sensor and hope will resolve my problem.

Thanks again
