2011 Audi A4 Excessive Oil Consumption (2.0T): What It Really Costs to Fix
Quick answer: 2011 Audi A4 excessive oil consumption (2.0t) typically costs $50 to $6,000 at an independent shop, depending on which component failed.
Applies to: 2.0L turbo gas only. Other versions of the 2011 Audi A4 do not have this problem.
What the Issue Is
The B8 A4's 2.0T is the engine behind Audi's best-known oil-consumption case. Asghari v. Volkswagen Group of America (C.D. Cal. 2:13-cv-02529), which received final approval on May 29, 2015, covered 2009 to 2011 A4, A5 and Q5 models with the 2.0T after owners reported engines burning oil between changes, setting low-oil warnings and, in bad cases, fouling plugs. A 2011 A4 sits inside that class; A4s from 2012 on were not part of it.
The settlement gave class cars free repairs for excessive oil consumption up to 8 years or 80,000 miles, a service fix (a new crankcase pressure regulating valve, front crankshaft seal and engine software update) offered for 18 months from January 28, 2015, and reimbursement of past repairs. Every one of those windows has closed, so an engine that still burns oil today is the owner's to fix, and a failed crankcase pressure valve, which also raises oil use, is the cheap thing to rule out first.
The economics are stark at both ends. An unrepaired thirsty engine either lives on top-offs (cheap, tedious, a bottle in the trunk) or gets piston-and-ring surgery at four-figure European labor rates; a car with invoices for the settlement-era repair is the de-risked buy; and a verified low-consumption car is simply a normal A4. The oil interview is the central act of any B8 purchase.
Symptoms to Watch For
- 1.Oil level falling noticeably between changes, with top-offs routine
- 2.Low-oil warnings treated as normal, with a bottle of oil kept in the car
- 3.Blue-gray smoke at startup or under hard acceleration in progressed cases
- 4.Fouled spark plugs and misfire codes traceable to oil in the chambers
- 5.Consumption-test or piston-repair records in the service file, the paper trail of an affected car
Real Repair Costs
The range spans lifestyles: managed top-offs cost pocket money per year, piston-and-ring surgery costs used-engine money. The settlement's 8-year/80,000-mile repair coverage has ended for every class car. Dealer quotes for the piston job run well above the independent range shown.
| Repair | Typical Cost (installed) |
|---|---|
| Managed consumption (top-offs, per year) | $50-$200 |
| Crankcase pressure (PCV) valve diagnosis / replacementthe cheap cause to rule out first | $150-$400 |
| Piston and ring replacement | $4,000-$6,000 |
| Used engine, installedthe alternative some choose | $3,500-$5,000 |
Major issue: budget for it. Ranges are US independent-shop estimates with quality parts. Use them as negotiation grounding, not a quote.
Mechanic's Tip: Spot It Before You Buy
Run the oil interview before falling for the car: ask how much oil it uses between changes and what the owner keeps in the trunk, a top-off bottle back there is a confession, and a seller who knows their miles-per-quart number has been living the problem. Check the level yourself on flat ground and read it against the service sticker's date and mileage; a full crankcase means little on sale day, but a low one shortly after a documented change speaks clearly. Cold-start the car personally watching for the blue puff, then watch the mirrors under hard acceleration on the drive. Finally, read the file for consumption tests or piston invoices, settlement-era piston-job cars are the de-risked buy, and that paperwork is worth real money.
The Bigger Ownership Picture
Beyond this specific issue, budget roughly $2,000-$2,900 per year for scheduled maintenance and likely out-of-warranty repairs on a 2011 Audi A4. That is a typical US range from Avturo's ownership-cost table, an estimate rather than a quote, and it excludes insurance, fuel, and financing.

Frequently Asked Questions
Which Audi A4 years have the oil consumption problem?▼
The class action that defined it, Asghari v. Volkswagen Group of America, covered 2009 to 2011 A4s with the 2.0T, along with the A5 and Q5. A4s from 2012 on were not in that class. On any year, a failing crankcase pressure valve can raise oil use, so measure the specific car rather than trusting the model year.
How much does the Audi A4 piston ring fix cost?▼
Out of coverage, $4,000 to $6,000 at independent European specialists for the piston-and-ring job, with used-engine swaps at $3,500 to $5,000 as the alternative path. Rule out a $150 to $400 PCV valve first, it mimics ring consumption and is the cheap fix when it is the actual culprit. The managed alternative, a quart at a time, runs $50 to $200 a year in oil and vigilance.
Is the Audi oil consumption settlement still active?▼
No. Its free repairs ran to 8 years or 80,000 miles, the crankcase valve and software fix was offered for 18 months from January 28, 2015, and the reimbursement program has closed. Any 2009 to 2011 A4 is past all of it, so a repair today is the owner's expense, and repair records from that era are what add value.
Should I buy an A4 that burns oil?▼
Only at a price that funds the answer. A quart every 1,500 miles is livable for a disciplined level-checker at a serious discount and intolerable for anyone who ignores warning lights. Piston-job math ($4,000 to $6,000) or used-engine math sets the ceiling of rational pricing on a thirsty car; a repaired example with invoices costs more and is worth it. The mismatch to avoid is a thirsty engine at a sorted-car price.
