Failure Date: I was driving to work and as I slow down to park I heard and felt a pop in the engine. Luckily I was able to use the momentum of the car to park.
The engine would not turn back on. After work I went back and the car would not turn on.
The engine would just clank really loud. I had it towed home and the next day I called the mechanic. I then towed the car about a week later to the mechanic for him to check it out.
After a few days he said that the engine chain tensioners broke and caused catastrophic damage to the engine. The repairs would cost $4800 and or we can put a new engine for $6300.See. Failure Date: Driving vehicle and it started shaking. Got the car home and when I shut it off and turned it back on it rattled and sounded like metal. I was able to get it to the dealership.
2010 Audi A4 Timing Chain
I had it checked by mechanic and he told me that the timing chain and tensioner were the problem and I was just two months out of warranty. The next day the dealership called to tell me I needed new cylinders because the car would not start. Quoted me $7,500 to repair.
I do not qualify for the class action suit because my car did not break until after the window closed. Audi knew about the failure and did nothing to warn owners.See. Failure Date: We were just informed of a class action lawsuit involving timing chain and tensioner failure. This failure could cause catastrophic engine failure while driving and cause the vehicle to stop possibly at highway speeds causing an accident and harm to vehicle occupants. The lawsuit could result in an extended pro-rated warranty but no recall or repairs made to any vehicle prior to engine failure. Audi is aware of this problem and has issued a technical service bulletin to the dealer network but will not offer any repairs outside of the current warranty.
We believe all affected vehicles should be recalled and repaired prior to a catastrophic engine failure resulting in loss of life.See. Failure Date: Fully stock engine and drive train car experienced a timing chain tensioner failure.
Being an interference engine, this cause catastrophic damage and the car requires a new engine. I was fortunate this happened while stationary at a gas station. I had driven about 100 miles and stopped for gas. Attempting to start the car yielded cranking but no turning over. The car was towed to a mechanic who confirmed the failure via engine compression. The failure could have happened while on my highway drive at highway speeds putting myself and the drivers around me in danger.
This is a known issue and a class action settlement is taking place. The manufacturer should be forced to recall all affected vehicles for tensioner replacement. Failure Date: Driving home from work, all of a sudden my vehicle was revving while it was idle and at low speed, making it very difficult and dangerous to steer the car and keep it under control. Upon inspection, it was found that the timing chain tensioner had failed and had caused serious engine damage, causing the pistons to fire prematurely. Previously the tensioner was replaced in 2014 by Audi when the car had 50k miles and was reported as a 'weak tensioner'. My car currently has 92k miles. I believe that no replacement tensioner should only last 40k miles and cause catastrophic engine failure and put consumers at risk of not being able to control their cars.
Failure Date: Timing belt tensioner failing at under 70k miles but Audi suggests that no need to perform any timing belt related work before 120k miles. This causes catastrophic failure on the engine and entire engine needs to be rebuilt or replaced. There are several lawsuits and complaints in several states. I wanted to officially start this complain and I'm in missouri. These tensioners and chains should have been replaced under the original warranty or an extended warranty program since Volkswagen knew these components were defective and would cause premature and often unannounced expensive engine failure.
This is evidenced by the subsequent revisions to the tensioner and chain performed in late 2011 in an effort to correct the original defects.See. Failure Date: The timing chain tensioner failed causing the Audi interference engine to become out of sync resulting in the engine becoming totaled. This has become a common occurrence and is widely reported on 2009 and newer models. Below is an article with their assessment of the situation. The car had been taken in 2x for misfires and was diagnosed as an issue with the spark plugs, it is now clear that this was the timing chain being out of alignment and missed. Upon the engine light coming on the car was left parked until the day before the service appt when it was to be dropped off at the service location, at that time, upon starting the vehicle the timing chain tensioner failed and caused the engine to fire out of alignment damaging the engine.
When speaking to a member of the Audi dealership it was shared that another vehicle is in for the same issue and that they are seeing this occur more and more in their vehicles. This failure is also reminiscent of the 2007 class action law suit which prompted Audi to move from a timing belt to the for the same outcome occurring.

This failure is also reminiscent of the 2007 class action law suit which prompted Audi to move from a timing belt to the for the same outcome occurring. Failure Date: Vehicle began to run very rough and started to shake. Parked and stopped engine. On attempting to restart it briefly fired but then died and stalled. Subsequent attempts to start the vehicle resulted in it turning over with no apparent firing.
Vehicle was towed to the Audi dealer and we were informed it was due to timing chain slip. It appears from information online that the timing chain tensioner in this 2009 b8 2. 0t engine is defective. The head and pistons were all damaged and the engine was declared unrepairable by the Audi dealer.
Dealer charged $1300 for inspecting the pistons and wants $13,000 for a new engine. This vehicle had replacement piston rings out of warranty but at no charge to us due to the known excessive oil consumption issue (for which there was a class action lawsuit).
Audi increased the engine warranty from 4 to 8 years as part of settlement of this class action, but only in respect of failures related to the excessive oil consumption issue. Audi maintains that this issue is unrelated but the dealer service manager told me that anecdotally she's seen several such failures after piston ring replacement (I have this interaction recorded on video). Searching online shows that there are several websites selling replacement timing chain tensioners to replace the defective part that Audi uses on this engine. Audi refuses to acknowledge any fault on this issue. Red line speedworx website which sells upgrade kits to replace the defective part says that typically this failure occurs at 80k miles plus.
Since the standard warranty is 50k miles this means that Audi views itself as not liable for these failures. We are filing a lawsuit against Audi over this issue. Failure Date: At approximately 1000 miles on the odometer of my 2012 Audi A4 avant quattro, a strange noise began from the front area of the engine. The noise happens at the first startup of the engine regardless of ambient temperature. After about 2 minutes when the engine idles down the noise stops. Different Audi technicians at two dealerships have diagnosed the noise as 1) cam tensioners, 2) a bad bearing inside the cam case, 3) secondary blower motor and, 4) lash in the vvt system. None of the technicians have put a wrench on any of the named components because, according to the dealerships' service managers, Audi USA will not authorize repairs.
According to Audi USA, the strange noise is a normal function even though Audi customer service cannot explain why the noise was not apparent for the first approximate 1000 miles of driving. Failure Date: A4's have a poorly designed cam tensioner that eventually leaks oil. The cost to repair the item is approximately $1000. The dealer (carousel Audi) even admits to the fact that it is a poor design and there have been numerous complaints about it at the dealer. I've also read numerous complaints about it on Audi forums. The leak typically found shortly after the warranty period has expired.
I feel strongly that this should be a recall on all respective cars to have it repaired!See.
