I have a 2022 Defender 110. I have only had it a month and I have noticed there is a wind noise coming from the drivers side at speeds over 45mph and gets worse as speed increases. I t does have LED light bar fitted. Could this be the cause ?

 

Yes. Very likely!
I did roof bars once and took them off due to the noise...

 

Very likely from the LED light bar. I would also check the A pillar as noise from the A pillar is a known issue.

 

Ok. Thanks for that. Do you know if the light bars are easy to remove. It’s not something i will use . It was on the vehicle when I bought it.

 

Hard to tell without seeing a picture. If they are mounted on the roof by the edge of the front glass, they are likely secured by 3M adhesive tape, which should not be hard to remove, just make sure you trace all the electrical wires and disconnect them. Good luck.
