If you change the turbo, you need to install a new oil return line as well (everyone recommends it). At the VERY LEAST, you have to clean the line with brake cleaner (1 complete can at least) and blow it out.
Next: certainly ONLY synthetic oil 5W.
Next: OEM or MANN oil filters (Fram do NOT work, they don't have the right bypass pressure setting)
Next: if driven hard (under boost), let turbo oil cool down by letting the car run idle for 1 minute before you shut it down ('turbo timer').
And: only original KKK/Borg Warner turbos, or high quality turbo repair shop (factory rebuilt). NEVER, EVER Ebay China turbo (they are worth the metal the junkyard pays you for it, say: $10).
Other than that, there is really nothing that destroys a turbo. They can last several 100k miles. I drive mine hard (155k now) AND high boost (20 psi).
Let me know if you need a good turbo rebuilt (or, for a few $$$ more, you can have the K03 rebuilt and upgraded to a K03 Hybrid like mine (flows 180 g/sec with Giac PC 16, which (I was told) is actually a bit more than most K04 with chip are capable of).

I have have found a Mobil 1 oil filter that blew out its filtering media on an Audi 2.8l V6 and jammed the oil pressure relief valve open causing almost no oil flow to the cylinder heads. I have not seen a Mann filter do this.

Yup. Got careful after reading about the various filter bypass pressures Audi specifies for the different engine. Now have a stash to 10 Mann on hand!

Maybe about 20 pages back, someone mentioned that a tech (not sure if it was an AoA or an indie) said instead of the labor to remove the oil filter screen and check the turbos, you could simply check the operating oil pressure. If the oil pressure is running low, that could be your indicator that you need to replace the filter screen. I haven't seen it mentioned since then, does this seem like a way to easier determine turbo health for something like a PPI?
Is it possible to buy a car above 70k miles, to go to Audi and get an extended warranty in your name that would cover turbo failure?
