Shops quote $4,500–$6,500 for this one, and the quote usually isn't the ripoff, the job really is that big. Here's what's actually failing, what the correct repair involves, and the honest part: this is not a job I do in a driveway.
The 2009–2013 EA888 in the A4, A5 and Q5 shipped with low-tension oil-control rings, a fuel-economy decision that backfired. The rings carry so little spring pressure that once carbon packs into the ring grooves and oil drain holes, they stick and stop scraping oil off the cylinder walls. That oil burns in the combustion chamber instead of returning to the pan. Audi documented the problem in a TSB and revised the pistons, which tells you everything: this is a design issue, and it doesn't heal itself.
The PCV valve makes it worse. Its internal diaphragm tears with age, which throws off crankcase pressure and pulls even more oil vapour into the intake. Between the two, owners see consumption hit a litre per 1,000 km, sometimes worse. The oil that burns fouls the spark plugs, coats the catalytic converter, and leaves carbon everywhere it passes.
The real fix is mechanical: the engine comes apart and the original pistons and rings are replaced with the updated design, along with a new PCV assembly. Anything less, thicker oil, additives, more frequent plug changes, is just managing the symptom while the consumption slowly climbs. Run it low between top-ups often enough and you risk bearing damage, which turns a big job into a dead engine.
If your Audi is doing any of these, this is the likely cause:

Piston Rings & PCV Replacement (Oil Consumption Fix) is on my published list of jobs I turn down. It needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. That list is public on my trust page. I'd rather lose the job than learn it on your engine, and you should be suspicious of anyone who says yes to this over the phone.
So here's what I can genuinely do for you, holding a $4,500–$6,500 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $4,500–$6,500, have someone independent confirm that's actually what's wrong. This is a diagnosis, not the repair, no hoist, no lift, nothing comes apart. I scan it, test it, look at it with you, and tell you straight whether their diagnosis holds up. If it does, I say so and you go pay them with confidence.
Book the second opinion →At $4,500–$6,500 on a car that might be worth not much more, plenty of people replace instead of repair, that's a completely reasonable call. If that's where you're heading, get the next car measured before you hand over money: 150 published points, at the seller's location, written report the same day.
Book a pre-purchase inspection →Tell me what you've been quoted and what the car is doing. $100–$250 flat, at your location, and you get a straight answer either way.

Not so you can do it yourself, so you can tell whether the shop quoting you understands the job:
That's the job. It's why this one belongs on a hoist instead of in a driveway, and it's why $4,500–$6,500 usually isn't a ripoff, it's a big repair honestly priced. What's worth checking is whether that's really what your car needs.
Get the diagnosis confirmed firstPlain version: Piston Rings & PCV Replacement (Oil Consumption Fix) needs equipment a driveway doesn't have, a hoist to get under it properly, a press or a machine shop for the parts that come out, and a controlled space for an engine or gearbox that's in pieces for days. I work out of driveways with hand tools. That's not false modesty, it's the published limit of what I take on, and it's listed on my trust page alongside the warranty.
What that means for you: this page is here to tell you what's failing and what it should cost, so you walk into a shop knowing the job instead of nodding at a number. And if you want that number checked before you pay it, that part I can do, $100–$250 flat, at your location.
Consumption only trends one way on these engines. The longer the rings stay stuck, the more carbon builds in the grooves and on the valves, the more oil the cat ingests, and the more often you're catching the dipstick low. Run the level down once on a hot summer drive and you're risking rod-bearing wear, at that point you're not buying a ring job, you're buying an engine. Fixing it while it's just consumption keeps it a repair instead of a replacement.
We confirm before committing. An oil consumption check, a look at the plugs, and a PCV test separate a torn PCV diaphragm (cheap fix) from collapsed rings (the real job). If your consumption is around a litre per 1,000 km with blue smoke at start-up, it's almost always the rings, but we verify rather than guess.
Yes. The revised pistons and rings Audi released for this exact problem carry proper ring tension and better oil drainage. Once installed with a new PCV, consumption returns to normal, these engines are otherwise strong, and the rest of the bottom end is rarely the problem.
No. Piston Rings & PCV Replacement (Oil Consumption Fix) is on my published list of jobs I turn down, it needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. I'd rather lose the job than learn it on your engine.
Two things, and both are real. A second-opinion diagnostic at your car, $100–$250 flat, at your location, so somebody independent confirms that's actually what's wrong before you commit to a $4,500–$6,500 repair. And if you're weighing replacing the car instead of fixing it, a pre-purchase inspection on the replacement, $149–$399 flat, at the seller's location.
Because the useful part isn't the wrench. It's knowing what's actually failing, what the correct repair involves, and that shops quote $4,500–$6,500 for it, so you walk in knowing the job instead of nodding at a number. If you want that number checked before you pay it, that part I can do.
