turbocharged 420hp 4.0L V8 7-speed automated manual AWD
| 22000 mi | coolant leak at turbo |
| 12700 mi | Low power, rough engine, flashing check engine light. Problem gone after restart of engine. Dealer claims ECM software update fixes the fault codes found (exhaust cam position). Check engine light from a fault code from the secondary air injection system. Dealer performed vacuum test (requires removal of the front bumpber) and found a cracked T-fitting. Replacement of part fixed the issue. |
| 25000 mi | Black residue on turbos where coolant lines are connected -- lines replaced per TSB |
| 25000 mi | Installed TSB2035235/2 to address throttle lag that occurs while reapplying throttle immediately after braking. |
| 28900 mi | Engine occasionally will stall after fuel fill up. Dealer was not able to replicate the problem. |
| 36000 mi US $1400 |
Valve in oil separator failed causing a very loud high pitched whistle. |
| 37000 mi US $1500 |
Enginee stall after filling tank while car was hot. Problem traced to bad N80 valve and also required replacement of charcoal canister which was full of raw fuel. |

| 50000 mi | Exhaust flap motor failed |
| 67000 mi | PCV valve replaced |

Both turbo failed Audi covered 75% of out of warranty repair due to know issue of oil check valve and filter screen causing oil flow starvation to turbos |
| 54000 mi | Top off coolant in overflow tank |
| 55000 mi | no problem found. If problem persists, dealer will run full diagnostics. It may be a failing coolant overflow tank level sensor. |
| 4500 mi | Replace charge air cooling pump V188 due to internal short, which blew a fuse and took several engine sensors offline. Took a week to diagnose, order parts, and install. Also did 5,000 mile service. |
| 15000 mi | Small coolant leak repaired at the left (driver's side) turbocharger. Known issue that required the line and seal to be replaced with updated parts. |
| 33000 mi | Small coolant return hose to expansion tank developed 3 small cracks, causing a small coolant leak. Replacement hose ordered & installed. |
| 20000 mi | Coolant leak on line going into right hand turbo. Apparently a common issue with 4.0T V8s. Dealer replaced coolant lines and seals for both turbos. Issue has been resolved. |
| 27900 mi | Occasional hesitation in acceleration. I suspected it was related to a flash for the DSG, but the dealer replaced some of the ignition coils. |

| 79471 mi $200 |
Replace Engine Coolant Reservoir since we have had to add coolant on a number of occasions. Still losing coolant. The mechanic indicated that the coolant and oil usage is normal for the age of the age vehicle but when I compare it to my other vehicles it sticks out as being very high. Most if the vehicles require little or no added coolant while the Audi has to b topped up periodically. The vehicle never used to do that when it was new. |
2013 Audi A6 / S6 / RS6 4dr Sedan
supercharged 310hp 3.0L V6 8-speed shiftable automatic AWD

| 82000 mi US $800 |
Motor mounts replacement. Notorious of braking after 60k miles. |
| 26000 mi | Intercooler Radiator leaked from small rock damage through front grill |
| 64000 mi US $410 |
ECP light came on and car went into limp mode (restricted to <=3800RPM). They just reset the computer. |
| 81300 mi US $85 |
Saw two codes flash on secondary device, P2006 & P2007, which means there is a vacuum leak. Supercharger was removed to replace thermostat, mechanic may have left an air leak in the system to cause code and engine check light. Update: Turns out the dealership when they put it back together they crossed the vacuum lines on cylinder banks one and two, thus the check engine light. When they tore into it a second time they discovered their mistake and made the correction. Coolant temperature climbed as thermostat became stuck closed. Thermostat replaced, check engine light came on as I was leaving the dealership. Replaced by dealer under CPO warranty. Otherwise $1000. |
| 32000 mi | TSB 2034439/2 Intercooler radiator protection grill / shield |
| 78600 mi | Check engine light, Catalytic converter malfunction. Performed ECM Software level update. |
| 105000 mi US $1650 |
Road debris damage of supercharger radiator. Replaced, and flush and fill radiator. There was a TSB from Audi 4 years ago (TSB 2034439/2) that identified the potential for a rock to enter through the tiny slits (2”) in the base of the A6 grill. They then provided a free plastic inside intercooler radiator cover to try an prevent the damage. I received that TSB. However it was not enough to prevent this from occurring. Arguably it could be considered a design issue. I am annoyed that even after getting the TSB, I still got the issue and had to pay $1600 for the repair. |
