What's up my there z4 lovers. So I bought my Z4m more than a year ago and ever since I've been driving with a dirty and blurry dash... so I decide to remove from the car and clean it.
When I removed the the back cover I found what I call "the buzzer" cus I find the sound it makes.... annoying!!!. I'm talking about the device that BEEEEPS BEEEEEEPS when you start your car, you forgot to put on your seat belt etc etc. I hate it - so I put a sticker on it to tone it down, you'll see it in pic #4.
Braking the dash apart was a piece of cake and I washed the heck out of it, with a Q-tip I cleaned around the speed....needle and the computer screen, I did the same to the right side and the middle. Once it dried up I put it back together and back in the car... now my dash looks like new. I spent no more than an hour doing everything.
