Hello, it’s about the following car: Volvo V 70 II 2.4 Bifuel automatic from 12/2005 with currently 104 TKM. I didn’t really use the SuFu. Problem: 1. During the warm running phase and or partly when switching to petrol operation, the engine swallows up at lower speeds and goes off – can be started immediately and unproblematic again. It then does once, runs reasonably. That’s annoying, because I had almost someone sitting on it one or the other time… 2. In gas operation, the engine jumps into petrol operation and can’t be switched back at the switch again. If you restart the engine, it runs smoothly in gas operation. At first, it showed the error sporadically, no matter whether shortly after switching to gas or even after 50 KM trouble-free driving. Meanwhile, it does it at least once a day. Does anyone know advice? Thanks in advance, the Brosi
