What yellow light are you refering to?

FYI

We have a filter here that removes that 'orrible 'text speak' ordinary English is fine....

the fuel yellow light

It's a little difficult for anyone to diagnose a problem with the small amount of details you've given. You don't mention what car for example. Fuel gauge problems can be down to the sender, but cars with the smaller tanks have one sender and the larger tanks have 2 (I think that's the right way round).

You could try looking in the Wiki, both fuel and temp guage problems are covered in there. There is also the search function, which will bring up the numerous other threads covering the same problems.

That's odd,orange on all the BMW's that I have owned!

Would suggest that you check the brass nut on the back of the gauge for tightness(that's the earth connection)and have a check of the electrical connections to the sender units on top of the fuel tank.These can be found by removing the rear seat cushion and un-screwing the inspection hatches.

well orange then will that be the connectors on left & right side
