Humming noise turning left at low speed

[Doriginl]

Hi, so whenever I'm turn left quite sharply at slow speeds I hear a humming sound, it's worse when it's from stand still. It's recently been to audi (not for this issue) and there's a fault with the haldex pump. I thought that may be the culprit but after speaking to an Audi specialist garage today about replacing the pump he has said that the noise won't be from the haldex.

Is he wrong?

You can hear it here

Very hard to tell anything from that 3 second clip

Just posted it to try help hear the sound it makes. I looked at some other posts before making mine and a few people was asking to hear the sound, sorry.

Don’t have to apologise. For me the clip just needs to be a bit longer to make anything out. Perhaps with the wheel being moved lock to lock to see what happens.

Okay, I'll try and make a longer clip tomorrow. I shortened it as its just the same sound over and over. Lock to lock is fine, and I'm fairly sure reverse is okay, it seems to be full left lock going forward
