Hey All,

Im getting ready to change the oil on my girlfriends 2013 328xi and i got to be honest and embarrassingly have to say, i cant find the drain plug. This should be very simple. I've seen pictures and videos and there is a flap that opens to expose the drain plug. I don't have that flap. I've pulled off the guard underneath and still don't see it. Any help would be appreciated.

Some will say that if you can't find the drain plug perhaps you shouldn't be doing the job! It's further back than you would think, and has a metal drain plug for the xDrive models. I believe you can see it in your second photo, in the oval cutout. It's nice to have the wrench/socket for the oil filter cap to keep from mangling the plastic lid with pliers. Check this video:

Here's another video, but he has a non-x so the drain plug is different (plastic):

Here's a link to the shop manual write-up (from the TIS). Our '13 328iX does not have the cover/door for the drain plug. You don't have to remove the engine covers, seal or wires. It has a good view of the drain plug. Good luck!

You do not need a special tool for the plastic oil filter cap, just a rag/towel and a channel lock. Just be thoughtful and gentle.

An oil change on these cars is exceedingly simple and quick.

An oil filter housing wrench is very inexpensive. Amazon has one for $4.43 including free shipping https://www.amazon.com/CTA-Tools-A261-Cap-Type-86-Millimeter/dp/B002INSTHI

If the link ever goes bad, know that the part also fits Volvos.

With oil changes, nothing has to be very tight. The specified torques are not high/tight. I measure them but it's essentially finger tight then a little wrist pressure for the oil plug and slightly more for the oil filter housing.

As far as quick and simple, the Saab 900 (1981-1991) and Saab 9-3 (2003-2012) were the easiest in that no jacking or lifts were needed. The oil plug was off to the side so that if you had a medium length arm, you could reach it under the car. Mercedes Benz is not so easy because many models require removing the bottom splash plate. I heard that one Italian car in the 1980's required partial removal of the radiator to change the battery.

Yes, a cheaply made oil filter housing thingee is inexpensive, but it is one more unnecessary single-purpose tool one doe not need.

How about on some of the modern day Chrysler/Fiat/Jeep products? On some of those rolling pieces of junk, you have to remove the front tire and inner fender liner just to get to the battery.

But now days, on cars with oil filter inserts, you can change the oil and do the entire job without spilling a drop. In the old days you were cleaning up oil for days as it dripped from the side of the engine from that hidden spin on filter.
