Two weeks ago I bought a used 2011 Countryman Cooper S All4. I must say I’m very happy with car. It handles very well especially in wet road conditions. Yesterday evening I took the car for ride on the "Autobahn". The freeway was empty and could max out the top speed – 225 km/h (130mp/h). That is very impressive. Nevertheless, more or less 190 km/h (118 mp/h) is a bit more convenient because its not as loud inside as driving top speed and the car feels a bit more stable.
This might be a bit silly, but when I go faster than 190 km/h the sealing of the sunroof seems to be not airtight. It became very loud and I could feel a very strong draught of air coming from the front lip of the sunroof (which was closed).
Did anybody encounter the same issue? Maybe the sunroof needs to be aligned more properly?
From my point of view the car is able to run at least 210 km/h (130mp/h) – at least in Germany - therefore all components should be able to withstand the effects of the speed.

 

Lived with this for 5 years with my Clubman. One of the only options not ordered on my Countryman.

 

Well I never get the joy of driving on the autobahn at 130 but on the interstate at 80 I get some windnoise sometimes at the front edge of the sunroof. Most of the time all I have to do is open it just past the point where the deflector pops up and then close it back and the noise is gone. I figured it's just from opening and closing the doors and the pressure change popping it loose a little. Hey, at least it opens everytime which is more than I can say for the one I had in the R56.

 

I did some high speed driving (120mph) late at night in the desert last yr and at that speed the sunroof definitely was leaking lots of air

 

Would recalibrating the sunroof help with this?

 

I'm thinking about checking this issue with my dealer.
At the moment I'm hesitating because I only have issues at very high speed. During normal city and rural driving everything is fine. If the dealer starts to "adjust", it might lead to more problems (e.g. rattling).

I'll ask the dealer during the next planned maintenance and keep you informed.

 

Definitely need to adjust the sunroof. I bought a used 2009 and thought the wind noise was normal until I adjusted it. There is a copy of the BMW procedure over on BMW Planet. It was easy to do if you don't have a warrenty. Loosen up the 6 screws that you can see from inside in the sides of the sunroof and move the glass around then tighten down. Can't remember the specs right now but something like even to 1mm below the roof line in the front and a couple of mm below at the rear edge. I can look them up and post actuals if someone else doesn't. You check the alignment front to rear by slipping a business card between the seams and checking for even resistence to pulling it out at both front and rear seams. Then just tighten the screws back up. Fixed the wind noise for me.
