I picked up my new Fabia VRS on 1st March. On 2nd I gort caught up in the snow and manged to travel about 10 miles in 2 hours. During the journey the fuel gauge needle dropped to zero and the computer said I was empty too. The warning light did not come on. I knew had about 3/4 tank. The problem remained even after a 30 min break and starting again.

Since then though its been fine. Anyone else had a similar problem? Was it the cold weather? (Not that it was that cold 2 Degrees C)

Welcome to Briskoda. I can't say I have heard of that fault before, but you have 3 years of warranty to get it fixed if necessary.
