  1. [WIP] Cheap power meter for those unlucky ones

    I started implementing this feature a few days ago. IT basically uses an ESP32 to connect to a cheap Bluetooth OBD2 dongle (usual name is ELM327 V2.1). Today the CYD (cheap yellow display) got in the mail and ported the UI to the new board. The reason is that I cannot seem to activate the power...
  2. Rear right subwoofer squeal sound - how to remove cover and inspect?

    I have a squealing / scratching sound coming from the (right) subwoofer when hitting certain bass notes, even at low volume, especially stronger during acceleration or when going uphill. Sound like a loose styrene or something. Does anyone have a guide how to remove the cover and/or trims from...
  3. Multi-part question: job number, adaptive headlight, power meter

    I have what I assume is a job 2 2021 Premium Extended AWD, though the initial German certificate has a date of 20.07.21 as registration date and 07.12.20 of what I assume is the model conformity date (Datum zum K). Another piece of paper states 01.06.2021 so I assume this is the build date or...
  4. OBD2 USB adapter for Forscan in Europe / worldwide?

    Looking to code some Forscan options and thought I would go for the USB one since it will likely have a longer useful life and better functionality than anything that depends on a phone. I'm not interested in monitoring real-time parameters or doing FDRS (though it would be a nice bonus). It...
  5. New owner, new questions

    So I got the MY21 AWD car, European version, but still have a few questions after reading a lot: - the dash display is very sparse, is this by design? - no way to see the current charge rate - air recirculation is hidden behind the air vents touch option, is it automatic or any way to get to it...
  6. Dashcam + parking camera?

    I'm looking for a solution that would integrate both the dashcam and a 360 parking camera or similar. I have a local shopping mall nearby and have yet to come home without fresh light scratches, even though I go there not more than 5 times per year. Something that would stay powered on for 1-2h...
  7. Another thread about solar surplus charging

    Just wondering what would be some options for safely controlling the charging rate. I have my inverter and house batteries integrated into Home Assistant, grid consumption/injection is also monitored. I would probably not want to pull more than 3kW (@240V) except in special cases. The most I...
  8. Buying used, sight unseen?

    Hi all, I'm looking at a few MY21-22 cars in Germany that are about an 8h drive from me. They are all low-mileage (<30.000 km) and similar spec (AWD, P2) and all are from handlers. Having bought a few cars myself from Germany - either when living there or not - I was wondering if it's stupid to...
