I have an 02 plate Z3 which, in windy weather and sometimes when travelling at speed, makes a high pitched squealy whine sound - drives fine and the garage can't find it. It sounds like air passing through something at high pressure making this sound. Anyone else had this? Or got any ideas?

Try looking at the seal around the top of the windscreen where the soft top sits. Does it happen with the soft top down?

Hi I have an 02 sport z3 and mine whines as well but usually with a side wind as well.it happens with the roof down and i cant find the problem. It sounds like

the aircon heat reflector shields or some thin metal plate oscillating at high speed..It would be interesting to know if a car without aircon does it???

      BMW 2 Series

      As of last month, my first BMW. A 2025 M240ix, Skyscraper Grey. Just an old dude having a late mid-life crisis looking for some fun and excitement on the road. I did not enjoy the 75 day wait after placing the order. I know it's subjective, but I'm trying to protect and add to the car with ideas from family, friends,etc. I initially gave the car the full Xpel protection treatment. XR+ tint, full body Ultimate Plus PPF and Fushion Plus ceramic coating. Also installed reflector deletes and carbon fiber door sills. They will be installing the full interior PPF kit when templates becomes available. Also wanted to mention the floor mats on the car. Bought the complete set, including the trunk from TuxMat. Bar none, the best I've ever had for a car. Next came the performance parts. I had a Dinan carbon fiber cold air intake and inlet pipe put on the engine. Also installed their throttle booster and exhaust controller. Last was replacing the stock spoiler (meh) with the TRE ID-01 carbon fiber spoiler. The new intake made a small improvement in sound. Throttle Booster was a bigger surprise than expected. Exhaust controller not so much. Early next year looking to further enhance the exhaust notes. Any suggestions would be appreciated. The AA down pipe looks and sounds great. Due to possible warranty issues down the road, I may wait on that a bit. May initially start with the Dinan axel back exhaust?

      M240i wheel advice

      Thank you Dave, I'll give it some thought, I'd have to get a friend in the Midlands area inspect and collect which isn't ideal, just too far away for me. I don't think they will sell quickly given time of year so I'm in no rush, best wishes for Xmas and 2025

      Instrument cluster suddenly died

      Morning Kristian Welcome and Seasons Greetings If you repaired the fault by changing the board and the fault has repeated then my thinking is the fault is with the power feed to the instrument panel overloading it,could be Junction box related or Footwell control module related. A diagnostic scan is needed to try and track it down Dave
