[VIDEO ADDED] Fuel tank level indicator varying at corners and accelerations/braking

[jvictormp]

Hi!

I'm facing some strange variations at the fuel tank level indication when there is some g-force, I mean, making some speedly corner or acceleration or braking.

The pointer goes, let's say, from 1/2 tank to 3/4 or so in about 5-10 seconds, then comes to 1/2 again in 5-10 seconds again.

That makes the autonomy vary too, and it's so much annoying when you're next to the low level, because it keeps lighting on and off the low level alert.

I found a hose disconnected in the engine bay, I believe it's from the fuel breather valve. But after reconnecting it, the problem persists, so I guess it didn't have relation.

Does somebody know something that may be causing it?

After 5 minutes I put autonomy in the panel, and you can see it crazy too.

Looks like you have more problems than just the fuel level issue. Your dash is lit up like a Christmas tree.

Throw ISTA on it. Or get it diagnosed properly at the dealership. Then do the work yourself.

^ what he said. I don't know how you can drive with that light show.

Updating.

Found the cause more than a year ago.

First, one ABS sensor at the front. Changed.

Two, the wiring harness above rear right wheel well all split. Repaired.

All faults gone, fuel level working good.
