    Hi, Is it possible to fit a '99 E39 M5 steering wheel to a '96 E39 540i? Can anyone link me to a diy or other guide? I tried getting my local garage to do this a while ago but they said the fittings were different so they couldn't do it, but it may be possible with some tinkering. Thanks

Is there anything that can be done to make it more robust so it will last the life of the car and not leave me...

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    Hi guys, a few weeks ago, I went to my 1997 E39 540 and the clutch pedal went straight to the floor as it had leaked all its fluid. The carpets were slightly wet so I guessed it was the master cylinder. If you looked and pressed the pedal down you could see it seeping out from the bottom of the...
