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.

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.

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.

149500 mi US $15	Since purchasing with approximately 143,000 miles, the engine has used a lot of oil, a quart every 670-900 miles(!) A mechanic friend suggested adding Seafoam to the engine oil, which I did for approximately 200 miles before changing the oil. We'll see if it helps.
151500 mi US $400	Two (plastic!) coolant bleeder screws were broken and leaking near the supercharger. Had to be tapped out, remnants of plastic in threads removed, and new screws installed. After the repair, oil usage increased dramatically (1 qt every 200 miles or less!). Couldn't get back to shop to have them address for a few months, then went on a one-month long trip during which the car just sat. After sitting for that month, oil consumption has fallen to nearly 900 miles last time I checked. Quite bizarre!

I returned to the independent Audi repair shop. The owner of the Audi shop (an Audi expert) checked the car out. He did not find any reason for the ESP, EPC, and CEL fault. However, he suggested that the ignition coils be replaced. The ignition coils were replaced at cost with no labor charge as a courtesy for the inconvenience of having to return to the shop After having the ignition coils replaced by the independent Audi mechanic, the EPC, EPS, and CEL (blinking) lights came back on the way back home. The vehicle was then taken to the Audi deal for analysis of the codes. The dealer kept the vehicle for several days, but could not any reason for the codes. I was charged $300. This was essentially, a $100 charge to troubleshoot each code separately. Although I explained that the warning lights all came on at the same time, the service adviser indicated that they needed to troubleshoot each code separately. Later, the service adviser claimed that the time that the mechanic spent trying to diagnose the problem was easily double the amount that I paid. The car was returned to me without the mechanic at the dealer finding any problem. The codes were reset by the mechanic and did not occur again while the car was at the dealership.
115474 mi US $2540	EPC, ESP, and CEL (blinking) lights became illuminated again. Car was towed to the independent Audi repair shop.

Basically the complete engine cooling fan assembly was replaced by a used unit from a scrap yard because buying the fan control module is expensive and requires to splice the wires. So I decided to look for a good condition used assembly and just a straightforward replacement to keep the wires intact without any splice connection. This fixed the ac and engine cooling. BTW diagnosis reviled that the fan control module as malfunctioned and the condenser pressure sensor fault.

Also the steering column actuator is faulty, symptoms are that you can't turn on the ignition or start the car. Happens from time to time, you don't know when. My solution is to leave the key in the ignition and lock the car with the spare key, or reset the fault code with VCDS. Needs to replace the whole steering column (including the anti-theft box), costs around 2500 USD in an Audi workshop (and around 1500 in an non-Audi workshop).
