Tonight my MKV Golf R32 started making a very nasty noise and before it goes into VW for an inspection I'd like to know what you think.

Car:

51k
FVWSH
No recent knocks and only just serviced.
Driven generally only on long distance
No fast and furious gear changes etc

Problem:

Inside the car when coasting below 40mph there is a hollow grinding noise. It's metallic but still quite a low frequency noise. I suspect it's always there but just masked by higher speeds.

The noise is related to the speed of the wheels and I can only hear it from the drivers side.

If I use the throttle, regardless of RPM, then the noise goes away.

Outside the car I can hear a squeaking noise which matches the frequency of the grinding noise. Imagine getting an irate and indestructible mouse caught in your tyre tread. This noise again goes under load.

If I coast around a roundabout the squeaking noise on the drivers wheel quietens down. I can't tell too well if this changes the noise inside the cabin but I 'think' it did.


Thoughts?

Has the car been sat this week? Sounds like brakes to me.

Check there is not a stone stuck between the brake disc and the backing plate.

I did wonder about this too but it doesn't explain why it goes away under load. Very odd. Sadly I'm off to the US for a week so it'll need to go into VW. The missus is going to drop it in on Monday.

I had a stone stuck once and I could only hear it off power or going backwards. Like you I had a lot of expensive stuff going through my mind.

A stone would make more sense as this has come out of nowhere and appeared after a 20 minutes drive by my missus this afternoon so it's not like it's been slowly building. Fingers crossed x1,000,000

Now you have said that, I'm even more confident that a stone is the culprit.

Good luck and a safe trip
