Over heating caused by thermostat sticking. This problem was common on the 2.0 Audi A6 which was recall. The car overheats every time I drive. Also, I had a spark plug end ip in the cylinder causing damage to the inner wall of the engine.

I own a 2013 Audi A6 around 77K miles. I got the cel and brought it to the dealer. There is an internal transmission coolant value that is part of the cooling system and obviously, that component also helps keep the transmission temperature in check. The issue with this defective part is the valve malfunctions causing coolant to penetrate the transmission control module and from there into the wiring harness. When this happens, it is a catastrophic malfunction of those components and a potential fire hazard. Water and electrical do not mix well.

In late December 2017 out of nowhere, my car began to display the warning, 'turn off engine and check coolant level' (photo attached) ; this was very alarming as I take very good care of my car and have had all of the required maintenance done at the dealership. I immediately called and had an appointment scheduled at the dealer. Just a few days later on January 5, 2018 I took my car in for service and was told that the water/coolant pump needed to be replaced (attached). Unfortunately, I felt that the cost was too much at the dealer and I took my car to a reputable mechanic in the area who replaced the water/coolant pump. To my surprise in September 2018, Audi announced a recall for the water/coolant pump. To my understanding, this means that they are liable for any damaged pump. With that being said, I would assume that any issues related to the pump should also be covered under that recall. As noted on my service memo from the Audi dealership when I had my car inspected for the warning 'if not replaced, the engine's cooling system will not be operating efficiently and at the proper temperature resulting in catastrophic engine damage.' In February 2018, a little over a month after having my car's water/coolant pump repaired, the car started to idle when I tried to pull out of my drive way. Not even a block away and the check engine light flashed on and off and the car cut off while driving and stopped in the middle of the street. I was so scared, but relieved that I was not hit by another car. I waited a few minutes and was able to get it back to my home where I immediately had it towed to my mechanic who told me I needed to replace the engine. I didn't have him do the repairs, but I then had it towed to the Audi dealer who told me the same thing, to replace the engine.

The contact owns a 2013 Audi A6. The contact received notification of NHTSA campaign number: 18V229000 (engine and engine cooling). The parts to do the repair were unavailable.

Audi shrewsbury (780 boston turnpike, shrewsbury, MA 01545, (508) 581-5800) was contacted and confirmed that the parts were not available for the recall remedy. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Vacuum pump oil leak (06J145100G). 76K mi, found via multi point inspection on 10/25/18 (Audi of honolulu). Vehicle prod date: 07/2012, engine code: Caeb, transmission: 0bk, quattro AWD. The vacuum pump, located at the rear of the engine is leaking motor oil. Either the internal seals of the pump or gasket is faulty. Motor oil is leaking onto the exhaust, transmission, firewall insulation, engine belly pan, transmission mounts/crossmember, transmission belly pan, and lower rear of engine. Under moderate braking, white smoke would appear from under the hood (pressure forcing the oil through the pump seals, which then leaked onto the exhaust.) braking power is sometimes diminished due to lack of vacuum power to brake booster (air leak). After shutting off engine (after normal driving), a burnt smell would appear (whole carport would smell). Est cost of parts + labor, $1K(Audi of honolulu). Vehicle is less than 10 years old and out of warranty. I'm highly concerned of a potential fire hazard and reduced braking ability.

Vehicle began shaking, driving very rough and check engine light came and epc lights came on the dash. Car was not drivable. This happened less than two months after I had the water pump replaced for leakage and failure (which has now been recalled). I believe the two are connected, but Audi charged me a to replace the engine. I feel that the engine failure was a direct link to the issue with the pump.

I was entering my garage and the car kept accelerating. I slammed into any front wall doing lots of damage to the structures in and out as well as to my body. My car was totaled. My first accident ever and the scariest moment of my life. I have had prior acceleration/deceleration issues with this car. On at least 6 occasions, I was going downhill approaching a stop sign and the car seemed to stop responding (steering, braking, engine) and yet the RPM's were gong higher and the engine was racing. Very frightening since you did not know what would happen next!!!

This does not refer to any specific incident. After purchasing the car I began to notice that when I accelerated from a stop, the car always surged ahead after a fraction of a second. I was told that the turbocharger on the 2 liter engine "spooled" at 1600 rpms and caused the surge. It is a very uncomfortable feeling to find the car surging ahead when you just touch the gas pedal slightly. When you're stopped in back of another car, the car surges ahead and you have to be very wary of "rear ending the other car. Unfortunately, it is my understanding that this surge is a normal part of the turbocharger, but it creates a definite possibility of a slow speed collision.
