oil light sensor/sender

I had my oil changed on my 2001 330 CiC. Two weeks later, the oil light comes on (yellow) for a few seconds just after i start the car and then it goes off. The oil level is fine and the mechanic say it's just a bad sensor/sendor.

Anyone have this problem? what should this cost to fix? I've had nothing but problems with this car and i'm about at my last straw. Too bad, because i love the car.

This is a pretty common problem. Fairly cheap and easy fix. No coding necessary, just drain oil, replace sensor and put new oil in.

Pretty sure this is what you would need to replace.

Don't forget a new O-ring too.

I don't have your service manual, but I'd imagine it's located somewhere near the bottom of the oil pan. Look around for the existing sensor, it's probably held on by a single hex or philips-head bolt, like most other sensors on these cars.

I had the same problem 2 months ago. The technician indicated a small leak around the junction between the oil pan and the metal hose(for lack of better term) that holds the oil dip stick. The hose was replaced and problem solved. Good Luck.

Oil Level Senders are a common replacement item.

Easy fix.

-Located on bottom of oil pan (3 nuts)
-Drain oil
-Remove Oil Level Sender
-Put new Oil Level Sender in
-Bolt up
-Make sure the Oil Drain Plug is back on!
-Fill w/ 7qts.
