William's 330Ci ZHP Maintenance and Project Thread

[BMWCurves]

Just don't let it accumulate in the door jams from rain, etc. I did that once and it was like concrete trying to get it off

I moved my grandmother's car today and it's been sitting for months which has included cycles of pollen and rain. The wipers were nothing short of glued to the windshield. I had to physically tear them out of their stuck position.

• Refreshed the front roundel after the clear coat had started cracking (not sure why). I got it as a bundle for two since the roundel on my sister's 330Xi was really bad.
• Checked the oil level since having changed the oil a few weeks ago with Rotella T6 and a low level oil light was triggered on Sunday. Sitting just a smidge below full.
• Topped off the coolant with distilled water.

How many miles between the oil change and the yellow light trigger?

I’m guessing it’s a faulty sensor as he said the level was just below full...

Ah I thought he added oil and now it’s a smudge near full. Didn’t think it would be a faulty sensor as he replaced it recently...

San is correct, I changed my sensor only last year if memory serves. The oil light went on approximately two months after I changed it. I'm not concerned, I think a lot of it has to do with the fact that I live on a hill and no matter what direction I go I have to go downhill for a solid 5 minutes, which probably pushes oil away from the sensor in the oil pan, giving a higher chance for triggering a false positive for low oil

My oil light came on soon after I swapped it too... because it was low on oil

My oil level sensor is a little weird. It’s accurate when it comes on and it’s usually half a quart low. But the light doesn’t come on if I drive too little or too much. If I drive a mile or two it doesn’t come on even if the oil level is low and it doesn’t come on if I drive more than 30 miles or so. So if I’m making only trips more than 30 miles, then my oil level sensor won’t tell me that the oil is low. I can understand it not coming on when I haven’t driven enough cause it’s probably the intended design to prevent a false fail.

I noticed this behavior in my car as well... it's always after a longish trip that is comes on

I think the dipstick is a crap measurement on these cars. I went through the same ordeal -- yellow oil light comes on after shutting off the car, check the dipstick, level is perfect, wtf, repeat. I finally changed the sensor thinking that it was faulty, but noticed that I only drained maybe 5 quarts of oil when I was doing it...dipstick still read normal...fudge
