Wind like noise when driving

Nath90210 · Feb 3rd, 2019, 18:05

Today i took my car for a wash and on driving found that after 20mph a noise began to sound. The more i accelerated the louder it went. The sound is like wind blowing/hum The more i hear it the more it sounds like im on a bus....

I have a 2.0 v50 deisel no turbo.

Any ideas please.

If its a 2.0l diesel then it will have a turbo. It is probably the turbo spooling up that you are hearing. It will spool up at about 1800 rpm.

Do you have wind deflectors? :P

It does, took them off and still the noise persists... no loose parts, all windows fully shut, no holes or loose seals. Looking at a few sites it suggests wheel bearings starting to go..

The noise sounds definite like a continuous gust of wind which gets louder the faster im going. Its hard to explain...

With the windows open does it sound the same? With them open you should at least be able to tell whether it's coming from front or rear, top or bottom.

Interesting, my 9-5 has wind deflectors and you start to hear noise above 60MPH.

All V50 diesels are turbocharged so if you don't have one it's been removed and your dashboard will be lit up like a Christmas tree with errors.

Does the noise get louder proportionally with the position of your foot on the accelerator? If so, it could be a split in the intercooler hose that runs from the intercooler to the turbo. You'll see oily deposits surrounding everything near the split if that's what it is.
