I purchase an early 05 B6 1.8 about six months ago with about 110k on it. I have put about 4K miles, $4K into it so far. As soon as I replace one thing it throws two new codes, pretty frustrating to say the least.
I Love/Hate this car. Don't buy one of these unless you can afford to fix it, or fix it yourself. At this point it should be good til 200K but I'm not convinced.
-ECU- Coolant migrated through wiring into my computer and fried it.
-Turbo - was bad, upgraded to K04& remapped software.
-Oil Level/Temp sensor
-Engine speed sensor
-Shift lock Solenoid is out now but will still shift out of park if you know the trick.
I have over 160K miles on
my Audi A4 AWD 2.0 turbo now & it runs as good as the day I bought it , maybe better as it is certainly broken in now .
I have taken excellent care of this car at the dealer & it is a fantastic vehicle . Fast , smooth & reliable it was just driven 15 hrs back from NCarolina through the mountains in a blizzard with no issues or slippage at all -0- . Have new set of Blizzaks on this year for a terrible winter & the car just goes & goes , the only issue is ground clearance .
Over all its a great car before buying one make sure you do your homework on the car. make sure the car was maintained well . I had a 98 Audi a very long time ago and had nothing but bad luck with it and it was the first Audi I ever owned. I never thought I would buy another one. But I found a 2005.5 Audi A4 Quattro 3.2 that caught my eye. It had all the service records with it since it was bought new and it ended up being a one owner car and all repairs was done at the Original Audi dealership that it came from. I lucked out there. The car handles so great it hugs the road and still looked like new. So I couldn't pass it up . It was the best car purchase ive made in a long time . Only one thing I had to repair these cars are known for glovebox hinge to break. Which was a easy fix .
At 70,000 miles, I had to replace the transmission. I'm now at about 85,000 miles and am being told the turbo is failing and that the cost to repair will be in the $2,000 range. If I make that repair, I will have spent about as much as the car is worth today on just two repairs. In doing some searches, it looks like to me that Audi has a transmission issue in these cars. (Haven't seen the same complaints about the turbo, but I haven't looked a lot either.) Sent Audi a letter about my issues and didn't even get a reply. I now tell everyone who asks that I wouldn't recommend an Audi unless you ONLY care how the car looks and drives (when it drives).
The car was fine until the warranty ran out. I kept every service appointment with my car on time at only the Audi dealership and took excellent care of my car having it detailed each spring. Within a year of the warranty expiring my car would not start and at 62,000 miles and four years old my car needed a new $13,000 engine!!! The dealership told me they could not determine the cause and would not take care of any of the cost, which were more than the car was worth. They offered me nothing for a trade in and no deals on purchasing a new Audi, no financing. Audi does not stand by their cars or customers.
