How do u know that u need a oil change on a bmw 3301 2002

get a Haynes repair manual

Is this the oil pressure sensor you changed?

if i had new bmw i would let only the bmw dealership change oil and service the car period, bmw is a very expensive car every body cant work on them.let dealership do the oil change they the only ones can reset your oil service light,its not easy to reset if you dont know how. most of the time if you have new vechicle the place where you bought the car will cut you a oil change deal.

yea i think those prices are for a synthetic oil change because thats a lot to charge. that year and model just use regular oil. if yr boyfrind has changed oil before he should be able to change this one the only thing on this one is the oil filtor is not a spin on filtor its inside a aluminum housing on the drivers side of the engine and to take it off is just one big nut that u loosen from the top. all the rest is the same as any other oil change. just let me know if you have any other questions

I would need to know what size the engine is.

check the owner operater manuel , if a what frequency that lite is supposed to come on at could be you need to change the setting. if so those instuctions shoul be in that manuel

The oil should be changed every 4,000 miles. You can keep a log of the mileage at each oil change, or just divide the total mileage by 4,000. Change the oil at 40,000...44,000...48,000...etc.

If your talking about what would a dealership change, it generally consists of a tune up, including spark plugs, plug wires, air filter, oil change, pcv valve, and fuel filter. Thats also usually when they want to replace the timing belts. There may be one or two other things specific to BMW, but generally thats what you can expect.

Switch on ignition.

Earth terminal 7 (I've no pic sorry) and hold for 3 seconds.
Switch ignition off
That should do it

Hello.

I'm assuming you have an auto transmission, if you do, then if you are lucky changing your transmission oil might do the trick.

If you want to try this, then you simply need to change your transmission oil drive the car for a few hundred miles and change the oil again, this has in some cases solved the problem but its not guranteed.
