BMW E46: cleaning out the internal cabin air temperature sensor

Posted by jpluimers on 2019/09/06

When the internal air temperature sensor becomes dirty over time, heating/airconditioning either thinks it is too warm or too cold inside then over-cools or over-heats.

Cleaning the internal air temperature sensor is simple:

It is behind the little slots on the front of the HVAC control, which has a fan that draws air across the sensor. It can clog up with dirt and need to be cleaned with some compressed air.

If more fails, you can replace it with a more modern unit, see the pictures below that are from [WayBack] Guide To Your BMW E46 HVAC Automatic Climate Control Upgrade by delmarco | DIY

Raspberry Pi as CD changer in pre 09/2002 E46 BMW 320i touring

Posted by jpluimers on 2018/10/05

My pre 09/2002 E46 BMW 320i touring didn’t come with a CD-changer, and since the Business CD head-unit didn’t support the regular AUX mechanisms (see links further below), I’m researching how to add a Raspberry Pi as CD-changer.

A few things I want to accomplish:

  • Raspberry Pi powers up as it has ignition signal
  • Raspberry Pi powers down soon after it has lost ignition signal
  • Connected via the CD-changer connectors (iBus and audio) in the back

Some links:

Supplying power:

iBus/kBus/CanBUS:

If the model was more recent, it would at least support AUX, but it doesn’t by default and the work-arounds seem to emulate a CD-changer after all:

BMW DIY Poor Radio Reception Repair, AM and FM, E46 3-Series and Other Models | Bavarian Autosport Blog

Posted by jpluimers on 2018/10/01

I need to fix this on my own 320i touring: [WayBackBMW DIY Poor Radio Reception Repair, AM and FM, E46 3-Series and Other Models | Bavarian Autosport Blog.

Basically it’s using DeoxIT on all contacts having to do with the AM/FM antenna signals.

I already have a DeoxIT pen so that should work fine.

For the Touring version, the below picture should help. I got it from [WayBackwww.unofficialbmw.com/images/e46.pdf via [WayBackUnofficial BMW: E46
