Hello all, I have the problem, which occasionally spins to the tank indicator and the temperature indicator. Even if the tank is full, the tank needle falls again and again to about 30l or falls until the reserve lamp reaches. If this problem adjusts also the temperature indicator spins. I was told it could lie on the “control unit” (which would have been a very expensive to replace) I hope someone can help me here, because this problem is probably “typical” for Volvos. Greeting from Velbert
