Sunroof Air Leak

On our 2016 X1, we have started to hear air coming in from the front of the sunroof even when it is closed. There is actually no air penetrating the car but you do hear it, especially at highway speeds. When we push up at the front of the sunroof, the sound disappears.

We went to the dealer and they said it is most likely the seal, and if it is, that is not covered under the extended warranty and they would have to charge me a one hour as a diagnostic fee. I guess I will have my indy BMW guy repair it for a much lower cost and save me this ridiculous diagnostic fee.

Anyone ever have this sound in their X1 and is it the seal?

Thanks

I can't answer it for the X1, but on my e60 there is TONS of air noise as the car gets old and it is indeed the air seal. $50 and 1 hr of my time to rip it off and put it in.. and happy as a clam. I'm kind of surprised that something simple like that would not be under warranty for really a little under 4 yrs old. Honestly if that is the case I would certainly just do it myself if possible. You know what.. I suppose if it was the seal what you could do is literally put painters tape all over the outside seal and if it's quiet, then it is indeed wind noise from that seal. Painters tape will come off without leaving a sticky residue.

It's possible it's the seal...but you say the sounds goes when you push upwards on the sunroof. So based on that, it might be just an alignment issue.

Have you tried firstly, to 'reset' the sunroof? I think the manual usually outlines the procedure for that.

I remember a BMW master tech telling me that to minimise the wind noise from the sunroof, the leading edge needs to be a little lower than the car body, and slightly higher at the trailing edge..

cheers

I tried resetting the pano roof and the wind noise is still there.

As well, when I push up at the front of the closed roof glass when driving, the wind noise disappears.

Would that lead you to think it is the seal?

I have the issue with my roof. Dealer said because i bought the car in AZ and live in PA the weather variance from the heat to cold messed up the seal. Having replaced this week. Will let you know.
