e30 m3 oil level guage ?

[ericzz]

Does it even have one ? I am looking at my old motor and really am second guessing myself on this .I see no wiring ? and can not remember ever having the oil level light on ! 1989 m3 fyi

The E34 oil pan has an oil level sender that can be wired into the overhead check panel.

Does a 'vert have the check panel?

[ericzz]

Yes I have a check panel and I have 100 % m3 wiring body harnes in my car . My ? is I do not think that the m3 came with a level senso . there is a blank on my pan with no wires maybe this is my issue !

The level sender needed for the swap is specific for the E34 oil pan. If you just have a blank on the bottom of the oil pan, then you don't have the sending unit. The sending unit has a 3-pin connector.

If it's something that your interested in having, it's a pretty straight forward install.

does your check panel have an "engine oil" light?

the m3's should have a oil level light. the wiring is different between the 87's and 89's, but they both go through the c101 connector.

i think i have a bad sensor :( 150.00$

AFAIK, I was told that since you are on a THR WHAD, all you need is the sender for the pan, to wire a connector to the pigtails in the harness, then the body side of the C101 will take the signal to the check panel, but you need a non-M check panel to add the LED for the level, since that's not on a early build (like mine) factory check panel.

I'm doing the same thing, and that's what I came up with, but I'm not that far into my swap so I'm not sure if that's 100% correct yet.

My panel has the led it's on nice and bright only one left . I recall when I drove the donor car into the shop is read engine oil level low so I thiink I have a bad sensor .

[LINUS]

So what's the question then? I thought you didn't have a sensor in your pan.

Also, the sensor is just a float, so pull it yourself & clean it with brake cleaner, or soak it in kerosene or diesel for a day - once you can make it "rattle" by shaking it like you're whacking off - your float/sensor is working.

Double check it with a ohm meter, it's a simple open/close loop.

Once you're good you can chase the problem elsewhere if it persists.

My s52 has a sensor since the e34 pan included one . My s14 has no sensor in it nor did it ever . I have the check panel with an oil level led that is now lit . The sesor is not a float as per my conversation with THR it works on a heating element and the cooling of the level is what determines the level in the pan . After checking and probing my wiring is aces !

[LINUS]

Bizzare. I had mine out and I did what I told you, I had a full open/close loop and I could see the float through the caging.

Not saying you're not right - just that was my experience. I should check the wiring charts for more info, never did that. I'm sure it will show on a diagram.

Thanks for setting me straight - I'm probably wrong.

[Mike B.]

Glad you have it sorted.

So what exactly was the problem & what was the solution?

It would benefit us if we all did a better job of posting our solutions after a problem arises, imagine how great when we search key words that not only would we find the problem like others had, but maybe what a solution is too.

I will have your answer tommorow
