Audi S4 Engine problems by year

The complaint is about the motors losing oil every 1000 miles a 1qt is need each time. The engine is caused and burns oil fast to the motor to lose oil more rapidly. Needs to be replaced. My motor is losing oil! And so do other models havening this problems isnt good.

After engine cools down, timing chain rattle can be heard upon starting the car. Chain rattle means that plastic guides or adjusters are worn, and might go any second. Spoke with audi rep online, which advises me that this is normal, and expected. Knowing basics of engines and transmission, I didn't believe that something is "life time" and is not serviceable, especially if it's plastic (which tends to shrink and expand depending on temperatures, and then has fractures which snaps). Two different independent...

On saturday morning 12/15/2014 start my card and heard a rattle noise on the engine, first time it make that noise since I bought it. On my way to work I started hearing the rattle noise again but this time it was louder I was driving around 40 mph when this happened. The car started vibrating and kept making the rattle noise on the engine. I just bought this car not even a week ago, and already started having engine problems. I took it to the mechanic and found out the engine might need to be replace soon, since that's a common problem with this cars and that that's one of the signs that the engine might go bad soon. *Tr

Audi claims that the timing chain on those vehicles are lifetime and does not need to be service. Unfortunate the timing change tensioners are made of plastic which the wear out at about 50k miles, causing a start up rattle and eventually engine explosion from the chain coming of the guides and destroying the entire engine and causing a massive accident at high speed. Hundreds of problems like this one are reported online from thousands of people even youtube videos. Not to mention that every time you bring your vehicle and complaint to audi the claim that the rattle is normal; just to find out that is the first clue of future engine failure. *Tr

2004 Audi s4. Consumer states vehicle failed while driving, engine, power brakes and steering locked up *tgw the dealer informed the consumer, the vehicle had suffered catastrophic engine failure, which was most likely due to the failure of the timing chain or adjusters. The consumer was quoted a price of $24,000 for the repairs. The consumer has since learned it was a relatively common problem for his model and year. The specific mechanical flaw seemed to be that the timing chain coordinated the action between the pistons and the valves. The timing chain was supported by several plastic guides. The guides pushed against the chain by the adjusters. *Jb

2005.5 Audi s4. 104,000 Miles. Chain tensioner damaged. Cause damage to engine. Engine should be replaced. *Tr

Car started misfiring and within less than 5 miles in the highway then started to build up smoke inside the cabin, car then stopped and towed to a mechanics who confirm the diagnosis of misfiring of 3 cylinders and found overheating of the passenger side catalytic converter that lead to a melting a connector of the transmission. *Tr

Front headlights (both sides) flicker(blink) but not all the time. When they flicker I turn them off and then turn on again, then they are fine. But I am worried that it may go bad during driving causing safety issues. Its not the bulb issues as on-board diagnostics wouldn't detect the problem. It has happened several times over last couple of weeks. I tried finding solution online and found this forum http://forums.Audiworld.Com/showthread.Php?P=23809262. This tells me this problem is part of notorious design by...

Engine failure going 45mph due to broken valve spring. Faulty part documented in 5/2005 usa today but audi will not repair. *Tr

Car engine was misfiring - was informed a faulty coil pack was causing the issue. One week later the misfires started again. Two more coil packs were replaced. 2 Weeks later another misfiring episode. Car died at intersection so was towed in for inspection. Camshaft adjuster/cam guides had failed. Parts were replaced for 5k and then 2 weeks later cylinder 3 failed when valve and piston interacted - car died again on the highway. Car engine is going to need total engine replacement. *Tr

See the nhtsa odi complaints: 10267048, 10263937, 10262201, 10261864, 10261281, and 10294798. My second experience with the catastrophic engine failure of the "cam chain tensioner" components was in nov of 2009 on the bank 1 cam. Fault code "set point not reached (over-retarded)." With misfires to all cylinders on bank 1 - less than one year from the same failure on bank 2 (see nhtsa odi complaint #10294798). There was approximately 70,000 miles on the odometer. As I mentioned before, although the s4 is a low...

See the nhtsa odi complaints: 10267048, 10263937, 10262201, 10261864, and 10261281 my first experience with the catastrophic engine failure of the "cam chain tensioner" components was in dec of 2008 on the bank 2 cam. Fault code "set point not reached (over-retarded)." With misfires to all cylinders on bank 2 - all but rendering the vehicle unable to drive. There was approximately 54,000 miles on the odometer. Though out of warranty I contacted audi to no avail. I am sorely disappointed in audi for engineering...

At 44,000 miles my car has catastrophic failure due to defective parts. It is a safety issue as I stated above because many people experience the engine revving up. The transmission can also be a safety issue because it typically happens under hard braking which all of you know if you are in gear you slow down better if all of a sudden you pop out of gear you car does not have as much holding you back. *Tr

Catastrophic engine failure and seize at 70mph. Previous the failure, audi replaced bent valves due to timing chain tensioner failure. Less than 300 miles from new heads being installed, the engine failed completely. *Tr

I got in my car this past friday to leave for work and then my car starts rumbling and sounds like what can best be described as a muscle car. I only live a mile from my office so I drive my car in. While driving it seems like the car has lost low end power and is still idling with a rumble. When I get to work I pop the hood and notice the entire motor shifting back and forth and my buddy sees my exhaust is moving up and down. So I decide to get it to the local garage that has worked on my car before. He is only...
