| Oct | 2008 | 84000 | 6399 | Battery indicator lit which turned out to be a bad alternator. Occurred 150 miles from home and dealer gouged me while remaining professional and pleasant. While on the lift for the alternator (and battery) replacement, mechanic noticed a torn CV boot (so they say). While on the lift getting problems 1 and 2 resolved, mechanic claims that cooling system was also leaking and needed $1,100 in non-descript repairs. I refused this having no prior symptoms. No coolant problem has emerged since (1,000 miles)!! |
| Jan | 2009 | 89000 | 6000 | Self-dimming LCD interior mirror failed and fluid drained out, rendering self-dimming feature inoperable. Shop replaced. Climate control blower motor had begun making noise but still operated. I suspected failing bearings ands eventual complete seizure so I had it replaced. Auxiliary electric coolant pump was found leaking during timing belt replacement and so was replaced. Also replaced all idler rollers , tensioner and main water pump during t-belt service, which is a regular maintenance item. An oil smell (faint) could be detected inside car and while at the shop for the other service, they found both valve covers leaking. Both gaskets were replaced. While in the shop for other service, mechanic also noticed that plastic coolant tank was leaking and replaced. |
| May | 2010 | 622 | Steering became less precise and rhythmic noise emanated from front wheel(s) which began to grow louder and was then accompanied by an out-of-balance sensation. Garage replaced lower control arms/bushings and re-aligned front end.. Shortly after replacement of lower control arms, car manifest a speed dependent vibration. Brought back to same shop who claimed they could not 'feel' or diagnose anything wrong with car. | |
| Jun | 2010 | 103000 | 250 | Took car to a different shop for vibration problem. Had to accompany mechanic who then agreed he could feel vibration. Recommended new tires so I replaced all four despite two being ok. Vibration improved but was not eliminated. Decided to bring to actual Audi dealer instead of independent shop. Dealer agreed problem existed but pronounced the drivetrain sound and blamed aftermarket wheels (on car when bought 4 years prior!) Am at a loss now..... |

| Oct | 2007 | 75000 | 750 | There is a recurrence of a leak in the cooling system evidenced by dry expansion tank. Had to find leak--in seals of pump replaced 18 months ago--and replace aging hoses. |
| May | 2008 | 83000 | 2750 | Had leaking water pump and leaking oil cooler replaced - ended up going to the timing belt replacement while I was there - added to current cost, but was going to do it in 6 months anyway. |
| Oct | 2008 | 89000 | 2800 | Leak developed due to degradation of seals around turbo - that's what I was told. Leak was not severe, empty coolant tank resulted from 3 months of driving. Had to replace right side tie rod ends and upper control arm. |
| Nov | 2008 | 89000 | 900 | Lower control bar and upper A-arm on right side had worn joints leading to slack in the system, vibration at speed, and noise in low speed turns |
| Sep | 2009 | 98000 | 300 | Had a noise in the front suspension that sounded like things rubbing together that should not be. Had all links checked and lubed key areas. Suspect that noise was from sway bar friction. |
