75 v6 oil warning light???

[K18 NOB]

Ok im now a bit lost here, the top left warning light is flashing on my 75 which to me looks like a oil level indicator, when it first came on i checked the level and it was just under half way between min and max so i topped it up a little every so often and let it settle to see if there was any change but still nothing, its currently sitting just below max and i dont want to top up any more, the oil pressue is fine and always has been, the oil pressure light does NOT come on at any point other than on start up but goes out once the engine is started as it should

A few possibilities ive narrowed it down to here

- dodgy level sensor

- ive got a longer dipstick than i should

- ive got it entirely wrong and the light is for something else

- typical alfa electronics playing up

[K18 NOB]

Just another thought.....

-the oil could be too thin???

I topped her up with 15w-40 which the "oil guide" reccomended but i cant vouch for what was already in it

Failure of the "electronic dipstick" is quite common. My last car had this fault but I could get round it by switching the ignition on but waiting until all the ARC lights had gone out before starting the engine (only takes a second). Try this.

If it doesn't work then you can either find another sensor and replace it or bypass it completely. Not sure where it is on the V6 but you're looking for a screw in sensor (brass nut about 20mm across) in the sort of position that you'd expect to find a dipstick. It'll have a plug with two wires coming off it. Unfortunately, unplugging it will just result in the light staying on permanently as it relies on the circuit being complete to put the light out. So you need to run a short wire across both terminals to connect them together.

This will make the light come on with the ignition and go out as normal. OK, you won't have an oil level warning light any more but so what? In reality, these things are about as reliable as a Treasury Forecast and you have more chance of dating Cameron Diaz than getting an accurate indication of the oil level from it. Use the dipstick like everyone else!

The sensor you are looking for is on the right hand side (looking into the engine bay) of the block at the bottom next to the dip stick.

I to have this problem and have found that shorting the wires together didnt work me, but i have read recently that you need to short the two terminals together with a 100 ohm resistor. This will result in no oil level light but lets be honest they are naff at best anyway.

Hope this helps.

I didn't use a resistor but plugged the wire into each end of the plug then banged it back onto the sensor to keep things looking tidy! Maybe this did the trick.
