Hi, I've been searching about this topic but couldn't find any relative information. I have the obdeleven and use it on my mk3.5. The app has the real time gauges and one is the fuel quantity. Oddly, it shows quite below the indicator on my dash. For example, when my dash is 1 point above half, I'd expect it to be around 60-70% full, but real time guage quantity on obdeleven shows 43%. Is it normal? Thanks!
