Strange noises after driving through a lot of slush & snow

[Fireyjack]

Went out yesterday looking for snow in my A4 2005 2.0t quattro. Some roads were very wet, some very slushy and at times a good 8" deep in snow.

Was having great fun until the car started making horrible noises - coming from beneath the car.
It sounds like the sizzling water along with some very loud ' between radio station' noises. It was quite concerning! Even driving home along a main road - it continued to make the noises - but gradually faded as I neared home.

The noise was present whether freewheeling or accelarating, even at 10mph it was there.
When I stopped the car, the noise went - even when I reved the engine..

Today I've been out and there is a noise of chunning snow when I travel above 35mph. It's quite a loud noise and comes from beneath the car on the passenger side.

I'm thinking either the quattro drive system or the long-life stainless steel exhaust system I have?
Any ideas what this problem is?

Thanks,

Tim.

It's possible snow is building up between the engine under-tray and the sump.

Thanks. Had a good look under the car and there is some plastic covers hanging down.

Will get into garage tomorrow & hopefully no other damage has been caused.
