Injectors sticking, o2 sensors bad.AnswerIf you have a PCV Valve (Positive Cranckcase Ventilation) it might be full of oil that never returned into combustion chamber. Answermass air flow sensor might be stuck, throttle body dirty, new air filter needed ? tune up needed (new plugs and wires and cap)\to clean up the thottle body and mass airflow sensor, just open up the tubes from the air filter to the intake manifold, spray everything down with carb cleaner (i prefer engine degresser, but i wouldn't recoomend it unless your used to using it . . . anyway . . . grab an old tooth brush (clean it with gas or alcohal before you use it) and scrub down every little part you can find . . . you should also clean some of the external parts like the thottle position sensor, and linkages.
also, always use injector cleaner and throw 4 onces of marvil oil in with each tank full . . . shift at a lower RPM and take you foot off the gas !!
BMW recommends that the ATF does not need to be changed in the 320i.
where is the oil dipstick on a bmw 320i petrol engine
I have a 1995 320i and the battery is located in the truck on the passenger side and lift out the plastic tray. The battery is below the plastic tray.
Very high (higher than 318i) consuption for 320i's for very little gain. The extra weight in the inline 6 cylinder 320i, means that the extra power it generates is wasted on the extra weight in the engine. So performance figures are very similiar, but fuel consuption for 320i is significantly higher.
If like the 316 could be servicing lights? They count up towards the next servicing interval
It could be a speaker grille.
you turn it
You will need to use 5w30 synthetic oil in your BMW e90 320i. The brand name doesn't matter, just as long as it is 5w30 synthetic.
It would be an optional extra.
Google.com if your outside the US go to Google.us that way it is in English and then type in US Spec for a 1988 BMW 320I just like that
most probable cause is a faulty fuel sender unt. recomend removing and installing a new fuel sender unit.
