And yes a BFO bar was the finder of said problem. Thanks all who replied.

My mechanic who I trust checked main bushes and balll joints and changed what was needed for mot.
Am away from car for a week now so will follow your advise when I get back and post update.

Thanks for your input.

Any ideas.

Hi all. Hope someone can help with this issue. The car is a 2002 3.0i petrol with rear air suspension only. It’s done 163k I’m getting a knocking/clonking noise when I go over bumps in the road. It sound like is coming from the front both sides and has periodically got worse The front lower arms inc ...

Update.
Done a few miles now. Right hand side has gone back up to normal level and no warnings on dash.

Thanks for that. Checked the wiring yesterday  and all seems intact.
Have just replaced the sensor and reset the fault code. Will drive
to work tomorrow and see what happens

Update. Drove 5 miles warning back on dash.

Update. I have finally got round to getting the car in the air and looking at the sensor and arms. Nothing was broken arms on both sides were folded the same way. The ball joints on the arms were clogged up with sh*t so I remove the sensor and arm from both side and cleaned the arms to free them up ...

I've just got my scanner and it's showing

Thanks for all the good info guys.
I have just ordered an icarsoft diagnostic scanner so will plug it in when it arrives.
I will post back my findings. In the mean time I'll have the back wheels off and check the rear sensors.
Is there a sensor on both sides or just one?

Sorry can't seem to upload an image at the moment.
That arm I was talking about is the one that is attached to the track control arm. And then attached to the plastic arm of the vertical movement sensor.

Thanks for the info. This is the arm I that was in a bad state ( have attached a pic hopefully)and have now replaced.

Update.
Have changed the resistor and posted a pic of the old one.

Thanks for the replies. I've got a new hedgehog and will try and fit it tomorrow.
Will update as I go.

Thanks again.
