Hello everyone, I would like to introduce myself briefly, since I will certainly look past here several times in the future 😉 My name is Matthias, 25 years old and recently proud owner of a 2002 Volvo V70 Bi-Fuel “Premium” with currently 98tkm on the clock. As my nickname already says, I was connected to the BMW warehouse before – but as I am convinced of driving with natural gas, and my girlfriend has been driving a BMW 316g Compact with natural gas for a long time, we decided to buy a second gas car. So far I am very satisfied with the Volvo (but I also drove only 500 km) – but I already have the first error message in the display: “Bremsassist – Maintenance required” The message comes only sporadically (until now 3x). I have seen when switching to the winter tires that the brake pads are due soon – has that possibly to do with it, or are it the “sensitive sensors”? And now my next question could tell me which CD Wechsler to fit to the Volvo Radio HU 603. I have already offered to me an Ebay too expensively for me.
