ABS Fault Code 00257

Hello

Looking for a wee bit of guidance.

I keep getting the same fault code coming up. Only when it's wet. It disappears when the roads dry up properly and over summer I never get the fault.

The code reads;

00257 -166 01/01 Canbus

ABS inlet valve:

Front left (n101)

Spa toxic 006 - short to plus.

It does not cause any issues with driving.

I've had a look online and other car owners (non skoda) have had to replace this item and it's cost them £350. I don't want to pay that without at least trying a home remedy first.

Does anyone know where this inlet valve is on the car?

If I can get to it, I can probably fix it or even dry it out and insulate it from the elements.
