Answer
If you are mechanically inclined, you can do this yourself. In a tuneup, you will change the oil and filter(the filter is located in a silver round housing near the front of the engine, it has a 13mm bolt that holds the cap on. loosen the cap and then drain the oil, then remove the filter. reinstall the drain plug with a new washer supplied with the oil filter kit. replace the rubber o-rings and washer for the oil filter cap and bolt and reinstall them. fill the engine with 6 quarts of oil. you also want to change the air filter. the air filter is in a black housing on the drivers side at the front of the engine. it has tabs that push in and the filter slides out. spark plugs. remove the cover that says BMW on the top of the engine. you'll see individual ignition coils held by 10 mm nuts. remove the coils and then the spark plugs. reinstall new plugs(put a small amount of anti-seize on the threads) and reinstall the coils and cover. you should also replace the microfilter and fuel filter, but they are a little harder to get to, if you want to do it, let me know. where is pembroke pines?
