There have been wide-spread reports & complaints with Audi A4's starting in 2009. Audi settled a class-action lawsuit in 2015 but it only covered vehicles madein 2009-2011. If you look at any Audi owner blog or any car blog you'll find thousands of complaints about excessive oil consumption resulting in owners needing to replace pistons. In my case, I was given an estimate to replace pistons & timing belt for over $8,000 in 2021. There are additional class-action lawsuits pending against Audi BUT on my own I can do nothing and I have contacted Audi multiple times since they are "clearly" well-aware of that this is a wide-spread problem with their cars. HOW IS IT the NHTSA has no information on this problem" How is it that a recall wasn't instituted years ago? What are you doing to protect consumers from Audi's refusal to help owners" It is impossible that this problem hasn't been previously reported. I need this matter resolved, I need the car repaired & I need Audi to pay for the cost of repair based on their faulty manufacturing. Given that thousands of Audi owners are affected, clearly, this should qualify as a recall.

I have continued to notice increasing oil consumption on my 2012 AUDI A4. I have mentioned this to my dealership, however they kept dismissing it as an old car. I noticed that there have been numerous reports of this with AUDI vehicles. I requested for 2 part oil consumption test, which failed. Nonetheless, they keep suggesting that there is nothing to be done. Please advise, if this meets concern similar to other consumers with this issue.

Owned 1 year and just over 120ish miles TIMING CHAIN Jumped Required Head Rebuild and the Timing Replacement. Soon as those were completed and Car back on the road, OIL CONSUMPTION every 150miles with Carbon Buildup regularly on the rear bumper. Low Oil Pressure light soon to appear following up with Water Pump Housing Cracking, Replaced the water pump and low oil pressure is worse than before this repair. Checked Oil Pan for sludge, OIL PAN FULL of METAL, tear down the top end of motor inspection disclosed that both of the BALANCE SHAFTS and SPROCKET were destroyed teeth missing form gears, assuming that in addition to this that piston rings definitely must be fried so they will be replaced with the balance shafts repair. In Addition to this entire ENGINE being a Lemon and needing replaced or rebuilt, 2 smaller issues I-??ve had would be Wiper Motor is not even fast enough for major downpours so possibly needs replacement and also the rear backup camera is extremely difficult for viewing as it-??s foggy/pixelated/shadowy and during rain completely useless.

I have gone gone to the dealer numerous times visits right after I had the scheduled oil changes done. The oil light / consumption issue happens after I've gotten an oil change, but 7,000 miles before the next one is due. I get afraid thinking that my car is out of oil. I do not have any oil leaks. Oil is leaking around ladder frame. This has been a know issue for a few years that I have been having and Audi will not resolve.

My vehicle was included in a class action settlement in Volkswagen timing chain product liability litigation, civil action no. 16-2765 (jll)(jad). I purchased my vehicle several months ago and was unaware of this settlement at the time of purchase. At my first service appointment, I was informed that the timing chain and timing chain valve covers were in critical need of repair, and was given a roughly $2,000 repair estimate for the job. I performed research myself and discovered this settlement, and inquired the service advisor as to why I was not informed of the extended warranty and why I was not able to use it to get my vehicle repaired. The service advisor informed me that for my vehicle to be eligible for the repair and covered under the warranty, the timing chain would have to actually fail. Until then, it would not be eligible for the warranty. I thought this was ridiculous as it basically forces me to drive my vehicle while putting myself and my passengers at risk. I was told by the BBB that my claim could not be processed via their system because the vehicle was past the time limit for their requirements, but that I should contact the NHTSA along with my state(Illinois) attorney general office. I have done that.
