Thank you MJ!

Yes, OP, you have to have a route about...and I'd recommend a nice LED flashlight of around 100 lumens too.

Clean things up and find the highest source of oil leak...and work down. Also, don't assume it's oil...Power Steering fluid leaks a lot too...and although it probably isn't trans or brake fluid, you should look...keep an eye on fluid levels too.

The underskirt holds a lot of fluid and they blow back and off when you drive...so don't be shocked if you see fluid all over the place...and remember that just because something has a fluid on it, that doesn't mean that that's the part that's leaking. Use simple green, an engine degreaser, parts cleaner...and clean up things...drive around for a day or two...and see where you see fresh fluids.

HTH...have fun!

Clean up the bottom and drive. Then look with a good flashlight, like my favorite, the xl50!

Seriously, we don't know where the leak(s) are from and thus can't guess what it would cost...but it'd be a good deal more than what you could fix it for. Truth is, once you identify source of leak, you might not 'need' to do anything.

But, to give you an example, a post just today came in...the guy was quoted almost a $1000 for oil filter housing (maybe the gasket only)...still, that's $600 for what you could do in a couple of hours....first diy, maybe 4-5 hours worst case.

CCV is a horrible 4 hour diy too, but everyone here seems to manage it.

Oil filter cap is a 5 minute repair and that could be all it is...the 0-ring in the wrong place, or by mistake, doubled up.

We not that magical here...we don't know the source and thus can't guess a cost...though I would guess it's not what you think. Don't forget, oil drips down and then blows back. It could be from anywhere, really.

Just bought xl50 flashlight thanks!

You may know this as the PCV valve, except BMW has developed a much more complicated version of that $8 valve, and the $2 hose connected to it. The BMW system compares to a PCV system like a paper airplane compares to a B2 Bomber. It is infinitely more complex and expensive.

The VCG is the Valve Cover Gasket. This is the gasket that fits between the large plastic cover on your engine, and the engine block. On my old 68 Firebird, the previous owner had made a set of VCG's out of cardboard, and they lasted for 60k miles. You can not do that on a BMW. It is a $40-$60 gasket, and 15 grommets that are about $.60 each, if you buy them online.

Now, I suggest you read a lot more, and avoid threads where people ask about stains on their driveway as a way to find an oil leak. For all we know, one of those spots was where the neighbors dog took a dump.
