Fuel Gauge

[Ryoka]

Hi all,

ive got a Ford Focus LX 2006 (56) Estate Diesel, 1.6.

I purchased the vehicle September, put £40 in the tank and apparently completed 400miles(ish). Since then, I’ve been putting diesel in the car (£40-£50) and the gauge, once I’ve done around 200 miles, goes immediately to empty and the warning light pops on. After a few days, it goes up, but states I need to refill in 80 miles.

I’ve also found when sat idle with the engine running, both temperature and fuel gauge will drop to nothing and take a while to kick in again when moving.

Just wondering if this is a sensor issue or something more concerning? I’ve also had similar issues with the oil warning light! Many thanks

if both the temp and fuel gauge show they same symptons at identical times - dropping and going back up, then I don't see it being a sensor problem, more a problem with the speedo console unit inside
