Just driven through deep water.....

[bestinshow]

As per the title, I've just accidentally diven through some quite deep water, luckily slowly, didn't stall it etc. There is now what sounds like a grinding / water forced against a panel noise when the car is moving, no noise when cat is stood still. No warning lights, starts first time, performance and temperature fine etc.

Question is will this dry out over time, or have a I done something here ? The water in the puddle didn't come up very high, at the mist maybe halfway up the wheel.

Any advice or experiences very welcome, the car is a diesel Saab 93.

Thanks

No other U-boat captains out there ?

Well, of it stands there it could speed up corrosion, but it should just dry up. Try to bounce the car when still and see of you can pinpoint the location.

Stop would be a good start, water doesn't compress very well.

Just get the cat to stay still all the time and you can drive around perfectly happily.
They sleep most of the time anyway.

(probably just some water trapped against a bulkhead or something, no?)

Water's probably pushed your wheel liner against something rubbery at a guess, or you've taken on water in the under tray and it's being weighed down

I'm hoping that the noise isnt coming from the engine bay, from what you've said there's no mechanical problems?

[bestinshow]

I'm hoping so....

The noise gets a bit louder the quicker you go ( no noise when car isn't moving ), so trapped water against the bulkhead makes sense I guess

Thanks

I'd guess something like this. I wouldn't have thought it would still be holding water somewhere - should all drain out fairly fast. I'd have thought it's more likely that wheel arch liner is rubbing on wheel, or some bit of plastic underneath has been pulled loose and is dragging. Have a good look at all of the plastic bits under the car and around the wheels.

Front of undertray pulled down by the water, causing it to rub on the ground.
Happened to a work Astra I was driving through floods a few years ago.

It should be purring like a kitten.

Been some floods in Aberdeenshire today - there was an Audi driving away from one which was making a screeching noise not unlike a train cornering or stopping!

Wife of a friend of mine drove his DB9 into a flooded underpass in the South of France and got stuck there. £14k for a new engine and it's not covered on insurance. So good luck to you.
