I need some help. I have a 1985 BMW 325e. I have a question how the Oil Service light works. Before the light would light up for a second while I started the car and then disappear, ln the last two weeks 4 bars would stay light up for about 5-6 seconds then disappear, now this week only 3 bars would stay light up. I just change the oil two days ago. I try to reset the oil service light by using the skinny wire and nothing happened. What does the light means and how it supposed to read them?

I do not use the oil service lights to change oil. It takes way too many miles to indicate an oil change, good way to gum up an engine. I do mine every 5000 miles - its easy to remember. When the odometer reads xx0,000 or xx5,000, it's time to change the oil. Unless you hammer your engine, I think any brand or wt oil works. My car had some repair work done by a reputable shop, when it came back, the mechanic had put 5-30 oil it it. So I don't worry anymore about brands and weights.
As for your lights, have you reset them previously using the wire? Paper clip works for me. Seems to me the lights stay on all the time. If yours are malfunctioning, maybe it's your service indicator board or batteries. Be tempting to put black tape over the lights. If you keep your BMW for any length of time,you will grow to hate the warning lights and sensors. They always break before what they are indicating fails.

I usually change the oil on all mycars at 3000 miles but since this vehicle takes synthetic oil, I am going to dothe change at 4000. The board on the car was change to an aftermarket new onethat doesn't require a battery. I try to reset it, but I am thinking that Iused a too skinny wire, because it didn't do anything. The car only has 75,000miles mint condition, I am not to put tape to cover the light. Good suggestionbut Nop. I am trying to understand how these lights work, do they light up andstay lid as its getting closer to service? or when they stay on for just 5seconds after starting the car it doesn't mean anything?
they should start at only green being on, when you reset the light, and then move through yellow to red as you get more miles.
I dont think these cars were advanced enough to do more than measure distance and maybe type of driving for th oil lights. I really think they just went off distance though
