Hi, Last week purchased a NV200 to replace my Kangoo which got written off. Really pleased with the van but today i noticed after i filled the van up with diesel that the fuel gauge hasn't moved. The trip computer say you have so much fuel till empty but the digital needle hasn't moved. The van had "1/4 of a tank" when i bought it. Is this a common fault ? Van is only a year old with 22000 miles. Possible warranty job maybe ?
