Rain Sensing wipers

[black325xi]

As far as the windshield being replaced by po, I am not sure. Everything looks correct and the windshield is BMW glass. I suspect the problem is the sensor mount to the windshield. There appears to be bubbles in the area around the eye. Planning to take it to the dealer in the next few weeks.

Bubbles where the sensor is attached can prevent the rain sensor from working properly. You want new glass that has the rain sensor already attached, not plain glass that someone has stuck a rain sensor on. Don't know about CPO coverage, but perhaps the windshield is warranted if it was replaced recently.

I had similar issue when I bought my 2008 x5, the issue was the gel pad between the rain sensor and glass, it worked even with bubbles in it after installing the gel pad.

So, I have OE glass (SG) not OEM - ie: no BMW logo. I suspect the previous owner had the glass replaced... but they reused the sensor.

BMW tried to reprogram it, hoping that it would fix, but no dice.

they then replaced the sensor and now it works like a charm.

because it was OE not OEM glass, it wasn't covered under warranty.

As for peoples comments about wiper behavior after ignition off, would programming that change in not fix it for you?
