Picked up the 3.6 M5 in Melbourne on Thursday. Drove it around there for a few days and it is now back here in Tassie with me.

Having a great time with it, love the sound and the feel of the power when the revs get over 4000, but still not sure I don't prefer the torque and more linear delviery of power from my M540i.

Anyway, on Friday night, as I drove towards the boat to take me from mainland Australia to Tasmania, a thunderstorm broke (and the temperature plunged about 10 degrees celsius to about 30 degrees). I turned the wipers on for the 1st time and no problems.

However, after about 5 mins, I noticed that the drivers arm wasn't going all the way down and in a few more strokes of the arm, stopped at the vertical position.

The passenger arm was working fine.

It appears that whatever grabs the arm and drives it no longer has the teeth or ability to grab any longer.

I stopped the car and you can now grab the arm and freely move it up and down.

Any idea what part it is that has worn out and how hard it is to fit.

Comments appreciated.

Cheers
