Audi Lawsuit Alleges That 2L Turbo Engines Cause Excessive Oil Consumption

A class action lawsuit alleges that Audi 2-L turbo engines consume excessive amounts of oil, eventually causing engine damage.

The lawsuit includes the following Audi vehicles equipped with 2.0T engines:

  • 2012–2017 Audi TT
  • 2012–2017 Audi A3
  • 2012–2017 Audi A4
  • 2012–2017 Audi A5
  • 2012–2017 Audi A6
  • 2012–2017 Audi Q3
  • 2012–2017 Audi Q5

According to Hernan A. Gonzalez v. Volkswagen, the primary plaintiff purchased a new 2015 Audi Q5 that quickly began consuming excessive amounts of oil.

The Audi Q5 lost power four months after purchase, and the Check Engine Light came on two months after the incident.

The plaintiff said he took his Audi Q5 to a dealer, where technicians attributed the engine problems to piston failure and recommended that four pistons be replaced. The plaintiff was charged over $7,500 for repairs, according to the lawsuit. For others with similar engine problems, repairs or replacement costs could skyrocket up to more than $10,000.

The plaintiff said his Audi Q5 would experience the same turbo problems because Audi uses the same faulty replacement parts ­– in this case, the same faulty pistons. The lawsuit itself alleges that faulty pistons, piston rings and piston heads are responsible for the 2.0T engine’s excessive oil consumption. Allegedly, the piston rings do not seat properly in the grooves of the turbocharged engine’s piston heads.

Several complaints have been submitted to the National Highway Traffic Safety Administration over excessive oil consumption in the listed Audi vehicles. Those listed below have been edited for grammar and clarity.

2015 Audi Q5: Excessive Oil Consumption

The Add Oil Light on my vehicle started to come on as I was driving. Initially, it was requiring oil added in between service appointments. I mentioned it at time of service and I was told this was normal at the dealership where I had all of the service on this vehicle done.

When it started reading low oil at just under every 1,000 miles, I contacted the dealer again, who had me bring it in and they performed a scope of the system. I was told that it was not using too much oil and, according to Audi, it was within normal usage of oil. I was very skeptical and brought it to a different Audi dealership for the next scheduled service. They told me there was too much oil in the exhaust and it was indeed using too much. At this point, I need to add a quart of oil at just under every 500 miles.

I did get a third opinion from a foreign motor specialist who works on Audis, but is not affiliated. He told me the car is using way too much oil and that the Audi Q5 vehicles are known for this. I have had all recommended service completed at an Audi dealer, most was done where the vehicle was purchased. I have only used premium gasoline, which is what Audi recommends. I am very frustrated with the conflicting reports and believe this is a known problem that Audi continues to ignore. This is an ongoing incident, which first happened at about 60,000 miles.

I bought it 7 weeks ago, at 44,000 miles. [There is a] severe oil consumption problem. I’m finding out everyone knows about already with Audi turbos and [there] was previously a class action. I’m putting oil in every other day and feel the pistons missing when I drive in the morning.

The car burns too much oil, I need to add 1 quart every 700-1,000 miles. There is no leak, but the oil burns and you can see the exhaust pipes are black. It seems this was a problem in 2011 4-cylinder Audis.

Excessive oil consumption occurs because the combustion chamber is not properly sealed off from the Audi turbo engine parts that need to remain lubricated. Because of inadequate lubrication, fragments of the piston rings flow through the Audi 2L turbo engines and damage important components. As a result, Audi Q5 and other Audi vehicle models may experience an immediate loss of engine power.
