#1020 of 1196 Re: 05 CPO A6 [ipod_nano] by erickpl Sep 23, 2008 (12:41 pm)
Replying to: ipod_nano (Jul 23, 2008 8:53 pm) 1. Not really. After the initial warranty, you pretty much foot the bill. BMW's CPO program and 100k warranty is IMO much stronger (previously own 2002 325xi and 2005 645ci).   2. It can. You using the button to start or the key? button start seems a bit flaky on ours.   3. I'd probably change oil yourself, just for peace of mind. I use Mobil 1 or Castrol (both meet VW/Audi specs - just verify the label). Can't recall if it is 5w30 or 0w40 that I used.   4. You don't have to remove the underside if you hvae the right tools. Filter is on TOP of the engine under that black cover just behind the grey header cover. I'm NOT talking about the black cover that houses the filter/brake reservoir, etc. If you have a fluid extractor, you can suck it out that way via the dipstick. I do that while the A6 is on wheel ramps and it forces oil to the back of the pan. Once I get all I can, I THEN remove the underside cover (silver button screws turn 90 degrees and come right out - easy), open the drain plug and get the remaining fluid. Be careful getting the oil filter out from the top (need 36mm socket IIRC). If you're not careful, you'll get oil all over the engine as you tip it. Plastic baggies are a HUGE help here.   Hope that answers your questions.   I can say after owning this A6 that we will NOT buy another. Even spark plugs (from the dealer) are 19.00 each. I got some NGK's for our A6 online for 8.00 each, which is still high, but a LOT easier to stomach. I'm putting on new pads tomorrow, but they're not dealer. They are aftermarket EBC pads (Redstuff) and they're ceramic.   I'd recommend a Bentley manual if you plan on doing more maintenance yourself. Knowing how to take the stuff apart will be 95% of your problem. If you figure out how to get to the cabin filter, let me know!   -Paul Replies to this message: ipod_nano (Nov 07, 2008 7:50 pm)
#1021 of 1196 Re: 2006 a6...wise to buy it off lease? [loggie] by erickpl Sep 23, 2008 (12:44 pm)
Replying to: loggie (Aug 14, 2008 8:00 am) If you are buying off lease, get the maintenance contract and/or extended warranty. AND make sure you know what is covered. Things like spark plugs run 20.00 each from the dealer and 130+ for front pads. Maintenance will add up QUICK if you're not careful. Some maint. warranties cover wear/tear like brakes and wipers. Some don't.   -Paul

Replying to: a6cvtowner (Aug 27, 2002 9:03 am) I have the same exact problem in my 99 A6. Replies to this message: erickpl (Sep 24, 2008 10:58 am)

Replying to: audiluvblues (Sep 24, 2008 9:52 am) Had a comparable problem in my 2002 BMW 325xi. Turns out the problem was a cluster controller unit failure (mainly a dashboard computer issue).   May be something similar here for your 99 CVT.   -Paul
#1024 of 1196 Oil Light Blinks Post Ignition for 45 Seconds by a0kia Sep 24, 2008 (11:02 am)
I had a head cover gasket leak which resulted in a light that says "OIL" to blink for up to 1 minutes every time I turned the car on. The light would go away and be replaced with the regular odometer reading every time. I had the gasket replaced and the leak stopped, but the OIL lamp still blinks every time I turn on the engine. I would appreciate any advice on how to reset the light. Thanks.
#1025 of 1196 2002 Audi A6 Quatro by rcrocker Sep 25, 2008 (1:43 pm)
I have a 2002 A6 that has either blown head gaskets on both banks or a combination of blown gaskets and cracked heads. Has anyone had experiance repairing this with products like "Thermagasket". Or is the repair easily done yourself with a repair manual? Shop estimates range from $1900 to $5000 to repair. Replies to this message: Mr_Shiftright (Sep 25, 2008 1:57 pm)

Replying to: rcrocker (Sep 25, 2008 1:43 pm) Nothing in a can is going to save you I'm very sorry to say, and it's not a very easy repair DIY either. Of course I don't know your skill level with tools, mechanicals, etc.   RE: Flickering oil light -- I believe on the A6 there is a high rpm oil light and a low rpm oil light, so I'd suspect a bad sensor. You don't have the 1.8T engine so sludge should not be an issue for you.

#1029 of 1196 Re: 99 A6 quattro CV outer boot [normanclayture] by musicalmadness Sep 30, 2008 (9:51 am)
Replying to: normanclayture (May 24, 2008 10:18 am) $950.00?!?!?!?   If you truly just need the two cv boots replaced, it should not cost you anywhere near that amount. Even if you needed both of the axles replaced as well, that would still be very expensive.   A lot of these repairs you can get done from repair shops that specialize in Bosch/OEM parts. I own a 2001 A6 2.7T with almost 140,000 miles on it. I had both of the front cv axles and boots replaced for just under $600. I'm pretty sure that the boot itself is like a $30 part.
