Hi Astroboy, referred your blog by right should prompt warning sign but guess my one cable totally putus that's why no warning sign.It was happened on Sunday evening time and no shop I known was opened ! I was damp panic don't know where to keep my car till next day as my condo is not really safe due to the integration of upgrading security system.Learn from bad experience nowadays if off work late not going to wind down any of the window instead just open the door to scan the access card. Sooo Kia su..

The alarm signifies the anti-catch algorithm malfunction. Our window has an anti-catch logic which need to be initialized to prevent the window from catching people's hand when in auto mode. When the lifter broke, the anti-catch algorithm will go crazy and trigger the alarm to warn people not to rely on the anti-catch mechanism.

By the way, we are supposed to exercise the lifter once in a while to prevent it from seizing which will result in lifter failure. Both my rear lifters failed due to hardly used.

Oh i see...very clear explanation and learn something new. My one is another way round, everyday wind down then unbelievable lifter spoil faster but since my car is 8 years, time to spoil la...

If that's the case, need to do some exercising later today :laugh: . Thanks for the heads up!

You need to do some coding for that to work. Either DIY or send to a mechanic that can code it for you.

hi nabilishes..how to do DIY, easy or not n need so many tools/wiring or what?

 

[nabilishes]

To do coding what you need for your E90 is a obd2 to USB cable which support K+DCAN Interface, BMW Scanner software 2.0.1 or higher, and a laptop.

You can refer to the GEneral Tech section in this forum for more info. There is a sticky topic titled "Feedback on BMW Scanner 1.4.0". 40 pages worth of info.

It should work.. it's a long press.. 5 to 10 sec. All BMW has this feature.. since the e46 era if not mistaken.

But Grace why would u wind down your left rear window everyday?

Hi Astroboy, my car was tinted and every staff's car compulsory to have security check even at back seat, so I have to wind down for them to check, quite troublesome but no choice.

 

[astroboy]

Wow.. so exercising the lifter often also can't prevent its failure. Useless design.

 

[Grace Wong]

Precisely...often exercising even worst. This mean for the past one year I am winding 240 times (working day 5days per week x 12months) the lifter get spoiled.I bought brand new my e90 and just wonder why the quality is unexpected worst. Conclusion is either the design or the quality is bad.

Assuming ur window motor is good, u can buy window regulator around RM 140 and diy urself. U can find it in ebay and mudah, diy mine in 1 hr. Lots of youtube videos.

 

[astroboy]

Kama, that's what I did. The regulator I bought 2 years ago was RM165. Didn't replace motor.

I spent less than an hour to replace the regulator. But more than an hour to reprogram the anti-catch function.

Takes some muscles in prying, removing few torx bolts, and unlatch some connecting rods. It should be quite a handful for Grace to undertake and the torx bolts remover tools is not a common tool you can find in a hardware shop.
