Could just be sludge as well. I wouldn't get to excited about it. If it's really bothering you, search for how to seafoam your car and give that a whirl. if you're REALLY concerned, do a compression and leakdown test on your car. It'll tell you if it's a head gasket (which I'm guessig you're thinking it is).

im not too sure what to think... why would sludge be in there? and i didnt notice anything on the dipstick soo...

 

did you take it for short trips before this happened?
take it for a longer drive and see if it clears out.
happens to me when i do 1-2 mile drives in town.

 

the last owner may have not used synthetic oil and just used crap.

 

hmm... well i plan on changin the oil and filter over the weekend, my first time with this car, any pointers, and which synthetic oil should i use?... i live in upstate new york.... and what would clean my engine? i did a small search on sludge and it said not to flush the engine cause it break down stuff that wont make it through to the drain and kind ahangs out in the pan and screen... lookin for best ideas thanks guy this is all learnin for me thats why i ask so many questions[8D]

 

I have a couple bottles of sea-foam at home, and I'll probably do the sea-foam treatment in the next couple of weeks, when I have time. It's okay to do the sea-foam treatment once or twice, but if you do it too many times, it will dry out the seals... not a good thing.

Your factory warranty is 4 yrs/50k miles from original date of sale, and if your car is CPO, your extended warranty is 6 yrs/100k total miles. Looks like you're probably out of factory warranty, but CPO warranty may still apply in your case. If you're concerned about the gunk on the oilcap, you can take it down to the stealership and pay the $50 (if you're CPO), and they can have a look at it, and diagnose & fix the problem.

If you do change your own oil, keep all receipts as proof of your oil changes. Anything on the list below is VAG-approved:

Your receipts will help document all your oil changes if your engine quits on you because of oil sludge.

 

alright, thanks thats an awesome list.... now if something does happen to my engine and i have all the receipts to prove oil changes etc, then what happens? does audi do something

 

k&n oil filer is what ill use... what exactly does the seafoam do?
