Oct 2008 61000 200 Leaking coolant after-run or auxiliary pump. Pump located in the "V" of engine beneath the intake manifold. Also required replacement of intake manifold gaskets as this is mandatory with R&R of intake manifold. 
May 2009 67000 40 CEL came on - system too lean & audible vacuum leak. Crack/leak in 4-way vac connector & non-return valve 078 611 933B. Temporary fix using RTV silicone made. Purchased part and replaced w/some vac lines. Car fully repaired in 4 hrs total repair time.

Replaced both left & right engine mounts and also front snub mount.

Apr 2007 74000 78 Windshield washer pump motor siezed. Blew associated fuse. I bought new washer pump, installed myself. Headlight bulb, changed myself. Took one hour, shop could probably do it in 30 minutes.

Oct 2008 89000 225 Noticed front rotors delaminating. Replaced all 4 rotors. Speedometer stopped working. Check engine light came on. Replaced vehicle speed sensor. 
Nov 2008 89000 1700 Steering was vague, car wandered, especially over bumps. Replaces all front control arms, tie rod ends, front struts and rear shocks. 
Dec 2008 90000 1100 Exhaust pipe cracked between resonator and muffler. Pipe needed to be replaced, as the area of crack was too thin to weld. Replaced entire exhaust system instead. 
Jan 2009 91000 100 Engine misfiring. One coil pack died. Elected to replace all 4, as the coil packs are a known issue, and they were only $25 each. 
Apr 2009 93000 300 Changed timing belt and water pump. Audi notified me the timing belt needed inspecting ASAP. I found the original timing belt would have easily gone to 105k. Changed the water pump while engine was open because of easy access. Did the job myself.

Jul 2010 102000 80 Car started misfiring. Intermittant issue over about 100 miles. Finally the coil pack died and set a code. I replaced 3 coil packs with OEM replacements. Had to order the 4th. Aftermarket coil pack lasted 12,000 miles, so I will replace all A/C blew cold at idle, but not at highway speed. Found vacuum leak, large 3 way hose split. Will replace next time I am near dealer, but fixed for now with duct tape. 
Jun 2011 112000 1 Vacuum leak found, fixed with tape but need to replace more rubber hoses. Vacuum leak causes A/C to work poorly, fools computer to think engine is under hard load.

They towed the car to the Dealership. Dealership replaced the water pump and timing belt. Check engine light was on for two weeks. Local auto parts store reset the light, it came back on after 3 days. While in the shop for problem 1, shop said they think problem 1 caused problem 2. They reset light but repaired nothing. Had to take car bac Check engine light on (as mentioned in problem 2 of trip 1). Light reset during trip 1. Light came on 3 days later. Went back, sensors bad, replaced sensors, problem solved. 2 weeks later light has not come back on. After getting car back from trip 1, washer fluid light came on. I refilled with 1 gal of fluid. Took back for trip 2, got it back, fluid low again. Shop says they filled it both times. Looked at it on 3rd trip, pump leaking, replaced, problem solved.

Nov 2011 142000 1270 Engine stalled, would not maintain idle without foot on throttle. Multiple codes, 2 O2 sensors intermittently giving trouble for years could be causing them. 3 sensors replaced at my request (due to reduced labor cost of the 3rd sensor). Same problem a week later, engine stall. Shop said ETC sensor giving readings that "didn't make sense" and suggested it be replaced. I requested shop replace the ETC sensor and fuel filter (it was overdue anyway). 
Dec 2011 143000 630 Same prob another week later, engine stall. Shop gave an OBDII recorder to get more info. MAF sensor throwing bad data, shop advised replace sensor and wiring. Engine ran smoother when it was disconnected. Sensor and wiring replaced. Same problem as before. Advised shop that no routine maintenance had been performed since about 80k miles, other than oil and tires. Shop checked regular maintenance items, found two bad spark plugs and 4 poor plugs. Replaced plugs.
