turbocharged 420hp 4.0L V8 7-speed automated manual AWD
4340 mi | Seal failure in water pump |
78120 mi C $8000 |
Both turbos failed, leaving me stranded in the middle of nowhere. Car was just over warranty period. This was a known issue with this engine. Audi US gave extended warranty coverage for this Audi Canada did not. Took 2 weeks to get parts I was very unhappy with Audi Canada but they didn’t care. My wife and I had an S5 and an S7 , now we have no Audi’s at all. |
60780 mi US $85 |
O2 Sensor replaced |
24180 mi | Oil separator failed. Turbo had to be replaced. |
24180 mi | Check engine light came on again. Back to dealer. Found nothing wrong. Afterwards okay for a spell. But just this weekend the EPC light came on and went off; the engine reverted to its shudder - which went away when I restarted it; CEL back. |
23620 mi | A complete piston kit was installed, they replaced a bunch of hoses and lines, did an alignment and a few other things. All under warranty and I'm told it would have been $15K otherwise as they pulled the motor right out. |
30380 mi | Shortly after getting the car back, the starter failed. The Audi techs came to my house and got it to kick over by bouncing it up and down. They then took it to the dealer and replaced the starter. Caused by static fault in passenger side engine mount. Also replaced engine mount. Damage to intake camshaft spacer. Dropped engine / tranny. Replaced intake camshaft, rocker arms and camshaft actuators. |
supercharged 310hp 3.0L V6 8-speed shiftable automatic AWD
74000 mi US $320 |
Engine was overheating. Replaced the water pump and the thermostat. This work required removal of the supercharger and moving the front of the vehicle into the service position. |
78000 mi US $200 |
The radiator for the supercharger intercooler had a pin hole leak that was probably caused by a small stone on the highway. I bought a new radiator and replaced the leaking unit and then refilled the coolant. |
45000 mi US $85 |
replaced water pump |
27000 mi | My A7 had to be towed to Audi WPB because of a thermostat failure that rendered the car inoperable. It was repaired within a day under warranty. Fortunately, as the repair would've cost over 1800. For a thermostat. |
47255 mi C $708 |
On separate occasions system displayed warnings and required to be completely shut down and restart to resolve. First was warnings about limited functionality with the transmission. Second was a fault with the start/stop feature. Diagnosis found ECM and TCM in locked state, tech could not perform diagnostics or follow test plans. Replaced main relay and ECM and TCM no longer in locked state - no further faults. |
54560 mi | Start-stop system failure. Error message/warning presented Previously required significant diagnostic and labor to correct. No fault found this time and problem has not recurred. However, this does call into question the reliability of this system. |
