Hello, my problem is this, with my Escort XR3i Cabrio the reserve light is burning, although the tank is full. I bought the car only about 3 weeks ago the tank was almost empty and the lamp was on. Didn’t think about it. So now I registered the car and fully fueled it. The tank needle went up but the lamp is still burning. What can it be?. It can’t lie on the tanker because the tanker clock goes yes. Gruss Kugk
