Fuel gauge suddenly showing incorrect....??

[SilverS8]

On Friday i was getting low on fuel and DIS was showing i had 20km left in the tank when i got home. Popped to the local store an hour later and then it claimed 50km left in the tank. Figured this was strange but think more about it.

Today me, my better half(as she claimed) and the kid went out for shopping, i was gonna get fuel close to the mall we were heading to, but on the danm highway with 40 km left in the tank it died...

After my better half had gotten her steem out i walked the 300 m to the nearest gas station. Put 6 liters in the car , drove over and put another 40 liters in the car. DIS now shows 40km left in the tank and the fuel gauge is only on 1/8..

No leaks anywhere.

Usually i can see 0km left in the tank and only squeze in 85 liters.


Any ideas guys?
