How much should it cost to fix the oil pump in a 2002 bmw 330

Your oil pump is located inside the oil pan but is part of the chain assembly. The first picture is with the oil pan removed and the engine upside down (the red arrow) the second is right side up red arrow pointing to the oil pump. That gear with the chain on it is left handed thread when removing and installing. Hope this helps....

check oil level, oil cooler and oil pump- wath pressure it gives.

Adjust the clutch.

If this is a hydraulically operated clutch, ensure there is sufficient operating fluid in the master cylinder.

If that is ineffective, replace the clutch.

Autozone will pull the codes for free and give you a print out. From there google's your best friend to see what the codes are and fixes.

put the key in the ign cyl and turn car on and off, remove key and hold unlock while pressing the lock button 3x,the locks will lock and then unlock if you have a second key do the same thing immediatly following except do not cycle key in ign just press the buttons int he same sequence

wether it's worth the cost of repair is something only you can decide, what is the mileage and condition of vehicle ? have you had the OBD codes read to see if there is a code to help with diagnosing the problem ?

The 'idiot' light only lights at about 4 pounds of oil pressure (not a good thing) or below which means that: 1. Sensor has failed (very common) 2. Oil filter may be too dirty to pass oil as it should and the bypass in it has failed. 3. Oil pump is worn and failing.
The latter two possibilities can mean that you have low pressure compared to what it should be (30-60#) but enough above 4# to keep the sensor happy.
The sensor isn't terribly costly, even on a BMW it should be less than $30 US and the labor to install it is about 10 minutes.

Hello There

There is no dipstick to check the oil with. The only thing you can do is to top up the oil to makixum level. There are two 17mm bolts on the gear box, accessed from under the car, the one at the bottom is for draining the oil, there is one on the side if the gearbox which is the one you need to add gearbox oil.

Hope this helps. Please don't forget to rate me.

Many Thanks

Hi, it doesn't sound like you have a problem as BMW's can use up to 1 litre of oil per 1000 kilometers, are you using the correct grade of oil?
it should be 5 W 30 fully synthetic

The fan may have a separate control module which is going faulty. I would let a dealer diagnose it for you (fix a price with them first) and if you repair turns out to be simple carry it out yourself to save on cash.
