Hello everyone! I have a problem with my lovely Fabia and it is happening to me for the first time. The car is a Fabia 1.4 MPI The power steering lamp is on, the steering wheel is stiff.
VCDS fault code:
00566 - Steering Assistance Operation: Implausible Signal
I cleared and it reappeared.
I checked the fuses. I also checked the ones above the battery, I only have 1,2,3 and 8,10. With them, everything looks good again. I don't know if there is another for the servo. The battery is one year and something. I measured and it is 12.40v at rest. I haven't had any problems with the steering wheel so far. It was very soft and I enjoyed it a lot. Apparently there are no leaks or anything.
Here some vcds measurements on channel 44 before changing the pump.
I changed the pump. My was KOYO 6Q0423155AA and i changed it with KOYO 6Q0423155AH. But the problem continues. I don't have the same error anymore but, I have error 01309 from channel cent. elct. Now I can't even connect to channel 44 where there is power assist steering. The original pump was a koyo 155AA and now this one is a koyo only 155AH. Is it possible that it does not match mine?
Please advice what to do :)
thanks in advance
