Default 2004 Audi A4 leaking oil

I cannot find the leak for the life of me but it keeps leaking oil, not a whole lot but enough to leave an oil mark wherever i park, i recently had an oil change and the tech did not find an oil leak anywhere.

Not sure how to help with the few details you have provided. Oil leaks can come from numerous places and depending on where you got the oil change, the tecdh may not be competent enough to figure it out.

Put the car on ramps and clean under the engine using engine cleaner from Autozone. Use a brush if necessary. Rinse and let dry. Drive car off ramps, start and let idle for 10 minutes. Look for drips. Drive car up on ramps. Take a flashlight and crawl under and search.

Also, be sure to use safety goggles, the kind that completely enclose your eyes. The engine cleaner stings.

Mine was leaking and I replaced valve cover gaskets and it stopped. There is a write up somewhere to do it yourself, pretty easy actually.

Take a look at the spark plugs. If there's oil in the depressions, there's a leaking valve cover gasket.

Do you find a general amount of oil on the back of the engine, dousing the transmission and front subframe? How many miles?

Another possible source (from experience) are all of the crankcase breather hoses on the driver side of the engine, under the intake and rearward of the oil filter. They disintegrate, drip oil, and if you can smell oil, this may be a good place to look - or feel as it may need to be.

Could also be the front axle seals, or the propshaft seal. The rear main can also leak, especially if your pcv valve is bad.

Yeah, clean the engine then the source should be easy to locate.
