General Comments:

My early research indicated that the 2.7T engine held the most "tweak" potential for the least investment, yielding, in return, the best performance. All true. Currently, with Dahlback ECU and racing cats I'm producing a max of 330hp, and approx 380lb/ft of torque.

Has the car been expensive to maintain? Yes. Has it been worth it for me? Yes. This rig is very comfortable, great in bad weather, carries 5 adults, has a roomy trunk, and probably gets up to 60 in the 5.6 - 5.8 sec range.

If you're into high-speed cruisers, the older A6 is a wonderful car. But be prepared to be very proactive on maintenance.

IMPORTANT: Unless you're very well-heeled, find a qualified after-market shop that specializes in Audi repairs and maintenance. I have one nearby, and I give them all my biz.

Faults:

Too much brake dust on the wheel covers - makes it look dirty. New factory brake shoes didn't help.

Anti-lock brake system went out nine months ago. Didn't want to spend the hundreds of $ to repair, so I'm sliding by with the conventional brake system. Still seems to be quite safe. Guess I'll find out how safe it is when I perform my next panic stop!

General Comments:

Extremely reliable.

Great traction in the snow.

Gas mileage so-so for an AWD V6. 17 city, 25 HWY.

Parts and labor very expensive at the dealership.

Very appealing to the eyes. Have had several positive comments from people walking by it.

Has as much room as a truck with the back seats folded down, which they do completely. Nice!

Dash hard to see because of not enough lighting.

General Comments:

I have had the Audi 2000 A6 2.7T for a couple of months now. Purchased it at 67000 miles and it has not given me any problems. I believe that the previous owner did not have problems with it either. I am so surprised because I have heard so many negative things about some cars, but when I purchased them they serve me well for years without major problems.

For instance, before I bought this Audi, I had a Ford Taurus 97, which I bought at 100 000 miles and people told me it will never last 10 000 miles. Was told a lot about endless problems with them, but drove it for 6 years with minor problems.

The Audi feels like a solid car in every aspect to me. I tend to think that these cars react to how we drive and treat them a lot of the time. I loaned my friend my Audi for two days, and when I drove it, it was driving different. Was not shifting smoothly, but after a while it normalized. One can almost say the computer knows it when you don't treat the car right. Guys, I'm happy with my Audi. Drove the S500 for a while and gave me problems at less than 50 000 miles.

Faults:

No major fault during this past 2 years. Running strong. Only maintenance.

Timing belt, water pump, gasket, seals and all the fluids (including auto transmission oil) replaced at 60K.

Most of the problems are computer glitches/problems. Don't believe all computer faults; the dealers just want to make money by replacing every parts that's diagnosed bad by the computer. You just need to buy a VAGCOM (NOT OBD2) and reset the computer when the problem arises, and measure all the sensor values by yourself to find out what is the real problem. Keep the battery in top condition, otherwise you will expect a lot of false code generated by the car's computer.

Engine consumes Oil. About 1 qt every 1000 miles. Audi dealer said it's normal. But for me, that's too much. After using Lubo Moly, it really helps reducing the oil consumption. Gasket has been replaced but doesn't help on oil consumption.

General Comments:

Great car and great handling. Not as quiet and comfy as Mercedes or even Lexus. But I love driving it, and a used one is SO CHEAP! Worth every penny. I bought it only $9,300 with 100K miles/5 years extended warranty. 1/4 of the new price. A lot of people do not believe in Audi, that's to my benefit.

Find the one that has a service/maintenance record and never had any major problem. Any car, once it's had a major problem, always has problems. Once a lemon, it's always a lemon.

IMHO, This car has a great reliability. I have several friends who have this car, and they're all satisfied with this car. All of them go to Audi/VW specialized independent shop.
