Hello! I recently bought one of these Volvo factory cars with Prins CNG system as young used. I am super satisfied, this is a very pleasant driving, and with a filling CNG (about 15-16kg) I manage the 300km. Can’t you complain! I notice a few details – does someone have experiences? 1. The automatic transmission is very smooth. When switching down from the 3rd to the 2nd gear, especially if you just let it run out and is no longer on the gas, it dangles e Is that normal? 2. Occasionally an error message comes, battery level weak or similar – I have already read with someone else in the forum. Is that because he was standing at the car dealership for a long time? 3. In the BC there is regularly an error message that the belts are not laid on the back seat – although there is no one there. Is this an electronic defect? 4. Does someone have experiences what retrofitting Bluetooth and/or Navi cost? Greetings Altenberg
