Knocking Noise underneath car when driving in the wet

[73mjf]

Hi everyone

Hope someone can help.

For the last couple of weeks when I am driving in the rain or it has been raining there is a knocking noise which seems to be coming from the underneath the car on the D/S...for some reason when it dry there is no noise

I took it into the garage who checked the exhaust, brakes, wheels & anything obvious but found nothing.

Any ideas?

We have exactly the same issue. We were told it's the abs , but never really understood why.

 

Would be interested if anyone else has had a different answer.
