Low fuel light

Post by misha »

Hi guys!
Low fuel light started acting strange in last few days.It keeps comming on while the needle is showing correct ammount of fuel(30l).
It usually shows up few minutes after start up.When i turn engine off and when i start it again it wanishes,but it comes back again in a few minutes...and so on and on and on.

What is the problem with the light?

Wiring bad somewhere. Your fuel sending unit could also be going bad.

I removed it today,opened it,cleaned contacts inside,shaked it a little up & down...closed it and returned it back to its place.Everything is ok for now.

Here are the pictures of it:
