PCV fault & Bluetooth OBD2 #850brick #obd2 #volvo850 #bluetooth

PCV is a common fault on the 850. it turned out it was just a disconected pipe that was the issue. I also wanted to descover what ECU I have installed on my 850 T-5. It turns out it is Motronic 4.3. Although I didn't open up the ecu case to look at the chip. I also wanted to use the bluetooth obd2 scanner from proscan to connect to the ECU. 14th October 2023.
