Hi, I was just wondering is there any tank reserve warning led? I can see the place in the dash and a yellow led, but nothing comes on when I run short of petrol. Is that right?

The light comes on when there is only 2.5 gallons left in the tank. I found with my E30 that the needle needs to be almost over where the LED is for the light to come on. The E30 gas tank is a little over 16 gallons.

Thanks AJ.
ghead There must be something wrong with it 'cause I finished up all the petrol some days ago and no light came on. Moreover, when I turn the ignition on and prior to starting the engine, no light comes on either. I even replaced the bulb with a new one but nothing. Any tip? (even though it's not a particular important issue nor of interest for you...)

If you take out the back seat you can remove the fuel pump access panel. Under there, along with the fuel pump, is the fuel level sending unit. If you unplug the wires going to the sending unit you can take a jumper wire and ground it out. If you ground out the proper wires the gauge will peg empty and trip the light. I'll find out on Monday when I go to work what wires need to be jumped for the light to go on. Or if you feel like it you can experment on your own. The connector that goes to the sending unit has 3 wires, one is a ground. Take a jumper wire and put one end of it in the ground socket of the connector, the with the other end put it in one of the two open sockets on the connector. Jumping ground to one of the sockets will peg the gauge full, jumping ground to the other socket should peg the gauge empty and trip the light. When I first got my car I thought the low fuel light was broken, but I just never got the car low enough on fuel for the light to go on.

You are correct on fuel in late model tanks but early cars had 55L = 14.5 gallon tanks.

Thanks for the info. When I looked up specs for my car, '89 325i, it said 16.X gallons. I just figured it was the same for all the E30's.

Hi, thanks all! Ok for the light, I shall investigate underneath the rear seat. As far as the capacity of the tank is concerned, mine says 58 liter! I know it means nothing to you folks! :lol:

ah, BTW, I've got another question which is not worth a new post:

at night the electric window switches are not illuminated and stay all dark. Is that alright or sould they become illuminated?

Lighted switches is an opition. Someone may have replaced them with the non lighted ones before you go the car. Just order some with lights and you should be good to go.

some of the earlier models did not come with lighted switches even as an option - however i believe the wiring was still there even on those models. best thing might be what my approach has been on my car: continue disassembly until the mystery is solved!

(the challenge is to not break anything that you aren't already replacing...)
