Z4 monitor sticking
Posted: Mon Jul 08, 2013 8:10 pm
I had this problem soon after I bought my 3.0 convertible. The garage had it back and said they had lubricated the mechanism and it worked for all of a couple of days and started playing up again. The got a quote from BMW for £1700 to replace and did not want to pay that so offered to take the car back. By this time I wass a bit fed up and as someone who is used to getting their hands dirty decided to take a look myself. I am doing this from memory so it might not be exactly right the good news is it was quite obvious.
1) remove the grill from beneath the monitor. The are two clips at the top each side you can see them with a torch. I used a stereo tool and a thin screw driver to actuate. Its a bit fiddly until you have done it a few times but it does pop out. Be careful of the vents because its easy to damage them.
2) Two screw underneath to be removed
3) At the back of the screen remove the small cover it just pops off
4) Remove the 3 screws (I think)
5) The unit should lift out. At this point you realise unless you get the unit out you cannot lubricate it. on the righthand side is the motor in a housing screwed to the side of the unit
6) remove the 3 screws and gently pull the housing off (it will come all the way off)
7) lubricate the centre pivot, the gears and what looks like a guide moulded into the plastic with White lithium grease
reasssemble in reverse order
It works lovely and feels great when you have saved £1700 from the stealer price or £100-200 for a 2nd hand unit.
Its been working great for 3 months now.
One tip I use my car 1-2 times per week as I have a company car so I always leave the screen up so every time I use the car the mechanism gets exercised. Its a small thing but if you don't use it its likely to stick eventually.
Hope this fixes your problem too. Any problems drop me a line.
