DIY Rain/Light/Solar/Condensation Sensor for F20/F30

All

Just complete my write up and would like to share with whoever looking to upgrade the very basic F20/F30 that does not come with auto headlight and rain sensor but has automatic air condition.

The total cost for me is $65 to get the OEM part from ebay. The nice thing is that only one part required. The light switch is ready; it just need a minor mod.

The full detail including part number/installation/modification/coding is in this file.

Have fun

Hey Everyone. I'm looking for some help here. I've sent the OP some PM's but he seems to have disappeared.

I followed the guide and everything works, except for one thing. The lights don't go off automatically. They come on automatically, and stay on until the you switch off or turn the car off.

Does anyone know how I could find the setting so the lights go off automatically as well?

Thanks!

It seems that your issue is the sensor sensitivity. Do you code for high sensitivity? If so, it will be on even in sunlight

No. It is coded "normal"

We also changed the light switch to an original one with the "A"

You Need to wait at least 5-8 minutes for the lights to go off after they come on automatically

Why?

In my car, I have "original" Rain-light sensor, and there I don't have to wait 5-8min.

Is this a coding thing?

Not sure if this will help or not, but I timed it. It takes 2 minutes in full light for the lights turn back off. There was no adjustment for that. Note that the sensor that turns on the headlights and the sensor that dims the idrive screen/extended dashboard panel is different. Those activate almost instantly.

Hey

I took a look in the various modules and compared mine with my fatherīs one.
It seem that the Kombi has to be coded for the sensor too, which I have not done

Even after coding Kombi and all other ecuīs, lightīs donīt switch off immediately.
It still takes a few minutes.

Could it be a Hardware thing?
But I think the only Hardware with is different to factory Rain- Light sensor is the "steering wheel ecu".

Try this one. This coding change sensitivity of the sensor.

Auto lights sensitivity
Fembody 3130
RLS_DEF_FLC_SCHWELLWERT_SATZ
Change from "normal" to "un_empfind"

This change does change my sensor sens. to my choice.

Ok. I took a look in ISTA/D for the problem, that the light needs a few minutes to switch off.
I found out that the problem isnīt a problem.

Cars with built date after March 2013, have a new Version of the Rain Light sensor. And with the new Sensor came a overrun time for the light.

So the difference is in the sensors.
Old Version - light switches off immediately
New Version - light switches off after 2min.

Coding from new to old or old to new is not possible

Yeah pretty sure that this is right. The car won't immediately switch back to DRL if you hit lighting conditions that warrant turning the headlights on.

Hello,
Thanks for sharing.
From where you get the sensor?

You can get the sensor from ebay or your BMW dealer.
