Audi remote aux. heater battery change Webasto Eberspächer

Описание: How to change battery in #Audi dedicated #Eberspächer EasyStart R+ remote control transmitter. You will need CR 2430 (2.4mm by 30mm) battery. Afterwards I'm also testing with FlipperZero if the remote is actually transmitting something. The SubGHz app shows communication at 868MHz frequency.

ℹ️ This remote is used across the Audi cars range. MQB and MLB. Including but not limited to: A3 (8V), A4 and A5 B9 (8W), A6 and A7 (4G), A8 (4H), Q2 (GA), Q5 (FY), Q7 and Q8 (4M).

ℹ️ It looks like VWAG switched from #Webasto TxRx system to Eberspächer TxRx in last years.
