Default Gauge cluster is all wrong

Speedometer, fuel gauge and MPG calculator and possibly the temp gauges are all off. How do I fix this?

You can start by telling us something about your car, like what year it is...

Gauges are all “off”. Meaning they are giving wrong values or blacked out / not working?

Speedometer and MPG estimator are displaying super low numebrs and the speedometer just refuses to work %25 of the time and display 0, fuel gauge is completely random as it shows an almost empty tank and when I fill only like 15 liters of fuel, it shows almost full

Leonidas,

There are very few sure things! One of those is www.batee.com So many of us on the forum have trusted our clusters to Brian and team.
