Power steering module & noise filter

Hi all, I had a bad / loose connection on my battery terminal and the intermittent power caused my EPS module to go bad. ( I have verified this as the problem through ohm testing of the wireharness etc etc ) anyway, I'm going to replace the module , but what are the chances the noise filter also needs to be replaced?
thanks for your time !

The noise filter is a commonly overlooked part when diagnosing EPS issues. But the who knows if yours is bad or not.

Maybe I should start there considering im finding the filter for like 15-20$ online. Crazy how much a brand new module is though. Luckly there's a bunch used options out there right now for me.

Oh also, do you know of a way to test the noise filter? I'm not getting power out of the module so I can't test if there's powering coming out the filter either.

Thinking if "varnish" insulation on exposed parts is missing than it may be likely to short like in motor windings.

Connection to ECU may also "show" in audio noise since has timing marks since it filters frequency for electrical connections.
