VW e-up! not charging – charge LED blinking yellow

/0 Comments/in /by

I had a problem where my VW e-up! wouldn’t charge from time to time. The LED by the charger inlet was blinking yellow indicating “Parking lock not engaged”. Of course I had checked that the parking break was applied and gear shifter in P position.

It turns out that also the steering wheel must be locked. So, after driving, before turning the ignition off I do:

  1. Put the gear lever to P position
  2. Apply the parking break
  3. Turn off the ignition and remove the key
  4. Turn the steering wheel slightly until it locks

Now apply charger cable and verify that the charger LED turns green after a while (or blinking green if a timed charge is active).

MacBook Air model 2013 running Ubuntu and working builtin camera

Macbook Air builtin camera on Ubuntu 24.04 LTS

When Apple decided that it was time for my MacBook Air model 2013 to die, by not supplying anymore OS updates, I decided to install Ubuntu instead of throwing a piece of perfectly working hardware away. The only reason this hardware was “obsolete” is because Apple decided it to be. The same behaviour goes for Microsoft by the way and I think we need a debate about climate impact where people need to buy new hardware just because Apple and Microsoft decides so, but that is another discussion. The reason you are here because you probably want your builtin camera to work with Ubuntu on your MacBook Air 🙂

Anyway, this is how I got the builtin camera to work under Ubuntu 24.04 LTS (these are my notes on how I did it from collected searches on the Internet):

sudo apt install git curl xzcat cpio
git clone https://github.com/patjak/facetimehd-firmware.git
cd facetimehd-firmware
make
sudo make install
cd ..
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie
make
sudo make install

Someone had noted that at this point a reboot was needed. I didn’t need to do that. It just worked by doing:

sudo depmod
sudo modprobe facetimehd
