My specific year model 2014 as well as all 4.0tt models 2013-2014 have a well known issue in which, by faulty design, the oil supply to the turbos is restricted therefor causing the turbos to fail. The flawed design is in relation to the oil screen that clogs and starves the turbos of oil and causing failure. Audi has since began installing a revised version of this screen to alleviate these issues in models after2016. But they have ordered a recall for year models 2013-2016. Even with service intervals cut in half(oil changes at 5,000 miles instead of 10,000 miles) it is still a very common issue. When the turbos fail the engine is unable to run and can pose a serious danger to the driver as well as other motorists on the road. Not only is this a real and serious safety hazard, the cost of the repairs to replace the turbos(due to a design flaw) is upwards of $6,000 conservatively. Audi has released an extended warranty to cover the repairs of the oil separator to 100,000 miles, but this only addresses part of the problem. Many times by the time the oil separator is flagged by the ecu, the damage to the turbos is already done. On top of that if the turbos fail due to the oil separator or due to the oil screen clogging, the only repairs and costs covered under the extended warranty are for the oil separator itself. For example, if my oil screen clogs(which leads to no cel) or if my oil separator fails in turn causing to turbos to fail, the only thing covered by warranty is the oil separator. The extended warranty also is also only allowed to be used after the item has failed and not preventatively. If these items were to be covered and replace preventatively the turbos would no longer be failing due to this issue. This is a very well known issue in the audi 4.0 community. Through audi forums and facebook groups it is apparent this is not a small issue.
2014 Audi S6 engine complaints
Page 2 of 2: complaints 11 to 15 of 15, newest first, as owners wrote them.
Suspension was replaced at 40,000 miles do to normal wear and tear. That was audi excuse. Suspension was replaced again at 63,000 miles. Engine mounts and transmission mounts were replaced at 63,000. Now at 75,000 miles, engine camshaft has failed and almost caused me to lose control of the car. Oil is changed every 3k miles and all maintenance is up to date and always done on time or before required. Car always smell like gas. Inspection found no issues. At this point, I am concerned with the safety of myself and my family because this car is a daily driver. I have contacted audi of USA for assistance. But audi is unresponsive. I have all service records but unable to upload due to file size restrictions.
The turbo charger bearings broke and destroyed the entire engine. The car only has 64,000 miles on it, I have since heard of many other people having this problem. The estimated repair bill from the audi dealer was $48,000, yes that's not a typo, $48,000 is way more than the car is even worth. We still owe $30,000 on a car that is essentially worthless without a running engine and is too expensive to fix. I believe audi should do something about this since this is a known issue.
Turbo failure - car stalled while slowing on a major road. Audi is aware of the issue and the dangers of the failure, but has not issued a recall, even though they have issued multiple technical service bulletins regarding the issue and admitting to faulty parts causing the failure. It is only a matter of time before someone is injured or worse due to losing control of the vehicles acceleration and use of engine.
