Hi. I posted on the general e46 board and the problem with my 2001 e46 325i SE saloon was diagnosed as a faulty oil level sensor. From my and other posts this seems to be a fairly common probblem.
Can anyone provide any info on how defficult it is to DIY fit a new sensor ? My dealer wants over 300 dollars for the job, so a DIY effort is quite appealing. Does anyone have and photos of a sendor unit and where it is located ? Can it be done using standard drive-on car ramps ? Thanks

It would be simple.

1. Raise the car (Ramps would work)
2. Drain the oil
3. Loosen the I think it's 2 but could be 4 small torx bolts
4. Unplug the sensor and put in the new one.
5. Refill with oil

I haven't done mine yet and my sensor is bad but it's pretty straight forward. The sensor itself is the expensive part I think ranging upwards to $90.00 plus the oil you need probably best to change out on your next oil change.

I'm guessing the only place to get the sensor is from the dealer.

Is this the problem where the yellow oil light comes on after start up and stays on only for a short time?

I'm thinking that from the directions Ivegotissues666 gave, it should be pretty straight forward.

If you have changed the oil in your BMW before it's really hard to miss since the sensor is on the bottom of the oil pan that you need to drain. Put it this way it you ca change your oil, you can change the sensor out no problem. Otherwise it may be better if you take it to a Indy shop or dealer.

:bump: from the past...

My oil light comes on for like 15 seconds, and then goes off. Usually after the drive, and I've turned off the ignition.


That, and my coolant level light is coming on for 10 seconds at a time in the middle of every other drive.

I dunno what is wrong with my car!

Your Oil level sensor needs to be changed.....and....you should change your coolant expansion tank along with the hoses and thermostat very very soon before your car overheats and you damage your engine. You might aswell do the waterpump while you are at it. It is going to cost you probably around $500 to do everything yourself but your car will be good for another 70K.

I had mine go out and I changed it this weekend. It's VERY easy.

1. This is a great time to change your oil. Drain your oil.

2. You have to remove the plastic FRONT AGGREGATE PROTECTIVE PLATE

3.Then remove REINFORCEMENT PLATE tha is if you have it. You have to remove this so you can get at the oil sensor. I can remember how many bolts there were but it's around 6 to 8.

4. Once you see the sensor remove the three bolts. Then pull it out.

5. Dont overtighten the bolts to the oil sensor or your going to have magor problems. Reinstall everything backwards.

Sorry it was only for E39 and X5 I have trouble keeping all these bulitions straight!! Although many e46's have had sofware updates to correct drivablity programs that may or may not have been done yet.

Refer to Service Information bulletins 11 51 00 (X5) or 11 08 00 (525i). Early production vehicles (both X5 with M62, and E39 (525i)) require a coding change to correct a condition where the low oil warning is set.

I'm having the same problem with my coolant level light. So I should change the coolant expansion tank and hoses and thermostat. Any body know the part #?

ok, i did this last week to an e46 325ci ('01). There are 8 bolts that hold the reinforcement plate in. ausfahrt's directions are right on point. the sensor is on the rear of the oil pan by the driver side :)

no reprogram was needed and the car is perfect now. damn this car is close to new now hehe. all belts, pulleys, waterpump, fluids, etc have been changed and nobody wants to buy at the low price :(
