Looking to buy 2001 allroad

[tewnick]

I am looking at buying a 2001 Allroad.

Black 2.7T Automatic with 93,000miles

Has had brakes replaced with ECS cross drilled rotors and Hawk pads, brake fluid flush, replaced all the control arms, outer tie rods, replaced the timing belt last year, replaced the air suspension with coil overs, both front CV axles were replaced, rear diff fluid has been changed and magnetic plugs installed. Newer tires.

Car looks very well taken care of. Owner has a 3 ring binder will all the service reciepts of everything he has done to it. He also has both keys and the valet key, original window sticker.
Interior look mint, Took it for a test drive and it drives smooth.

Has a pixelated instrument cluster.

Has the 3rd row seat. As well as the seat cover to go with it.


Scanned it for codes.

I knew about the EGT, & torque converter codes. It seams like there is something going on with the O2 sensors? Is anyone familiar with these codes?

I just want to get an idea what these items will run to fix before I buy the car.

I should be able to pick it up for $3500 is that too much with the items that need to be fixed?

After getting the Torque Converter replaced I plan to Have a tune added to it coding out the EGT, & secondary 02 sensors.

What should it take to get the Torque converter replaced? $1,500-$2,000?

Thanks in advance for your input.

:O well taken care of... with a million codes haha. Not making fun of you, I know what you meant. But the current owner should really have kept up on repairs.

Step one in owning an Audi (especially an allroad!) stay up on maintenance and repairs. You do not want to get behind in either of these things it will only bite you. Consider this while you're looking to purchase.

With a bad TC and a few other $100+ sensors $3,500 is a bit dear to be honest. The car is worth that for sure if it's strong, but the market has been showing that allroads with these kinds of conditions are maybe $2k? Some people are walking away with allroads with trans issues in the teens. As far as replacing it the TC itself is relatively cheap, price can vary as much as labor charge.

[tewnick]

I know what you mean.

Here is the listing. http://houston.craigslist.org/cto/5355012433.html

Not really worried about the purge valve or egt sensor.

Not sure if i should be concerned with the others.

[S6XTC]

Also bare in mind that one stupid little problem can cause multiple codes... A dying battery in my S6 caused about 8 different codes... replaced the battery cleared codes and none have returned for over a month now... Another C5 I worked on had a page of codes... cleaned all the earths/grounds and the battery terminals (they were corroded) and has been code free for months now :)

[tewnick]

Good point.

When I had a torn Boost hose it caused about 6 or 7 codes. Replaced boot , cleared codes and it was good.

He did have the battery go bad. He replaced it but did not have Vag-com to clear codes. But the EGT & Torque converter codes are not new.

[4rings2turbos]

It does look quite clean like you say. Really, if you're good with replacing the TC I maintain that it's worth $3,500. It's a lot of car and it's a joy to drive and when well cared for they're quite stout.

Best of luck to you, would love to see you in this section and at camp allroad

I would like get this car. But I want to make.sure that the price is not out of line for its condition. And I would like some advice on the codes. Not concerned about the Torque Converter, or EGT codes. But unsure of the others. If they are Secondary o2 related then no worries.

[twizz]

He seems like a reasonable individual, I would just find the cost of parts and labor for replacing all of the 02's and offer to split the difference with him. They don't seem to be causing an issue, and it doesn't seem that the car would have any reason to show those codes for anything but part failure itself. If you're having someone replace the TC, you can just have them toss in all new sensors while they are in there.

Car does look IMMACULATE, so I see the price there. If it wasn't so clean, I would suggest finding another from that price point.

[4rings2turbos]

N80 is a common failure point, I think they go for like $75? Easy to access and change on top of the engine.

Brake boost failure could be the aux pump in the near right corner (as you're looking at the engine from front of the car).

Not familiar with cat codes, will want to find out if they're bad and consider the price if you're in an area requiring emissions testing. Cats are $$$.

First step is to clear the codes and see what comes back.

[tewnick]

Any way to know if the codes are related to the primary or secondary o2 sensors?

[twizz]

Any way to know if the codes are related to the primary or secondary o2 sensors?

I believe being p0421 & p0431 indicates they are bank 1 & bank 2 secondary sensors. Potentially bad cats I suppose, but I don't live in a state where that is concernable. Perhaps you could use that for a substantial price drop :P

[tewnick]

If it is the cats would coding out the secondary O2s take care of that? At least from a check engine light stand point?

[Kaane]

EGT's are bad as well, those are expensive, or you can run simulators. The Cats could be bad or O2 sensors, one O2 sensor is bad for sure. Either way there is a 2,000 in parts needing to be replaced if you can do all the labor. Car looks clean, but has issues.

[tewnick]

I had an EPL tune done on my A6 and the secondary o2s were deleted without issue. I was told that when I have this one flashed I can have the EGT and secondary O2s deleted. So $100 for the primary O2, $75 for the purge valve, maybe $250-$300 for the vacuum pump. And I will be getting some quotes for the Torque Converter replacement. I just got done replacing the engine in my A6 and I don't feel like doing that again right now.

I guess my main concern is if deleting the secondary O2 sensors would take care of the catalytic converter code if the cats are in fact bad? Any thoughts?

[twizz]

If the sensors are working fine, and you have a clogged cat...coding them out will not be remedial. However if you plan to do that anyways, you could always piggie them and knock the material out and then that solves all the problems. Even nets you a small power gain.

[4rings2turbos]

Unless it's the main cats that are clogged, thats a bit more of a can of worms.

[tewnick]

I have seen several articles that mention that there is a firmware update. It is also specifically mentioned on the Ross Tech website.

Listed under special notes.

2001 Allroad with APB engine, see TSB 01-08-20 (TPI 2005579)

http://wiki.ross-tech.com/wiki/index...5/P0431/001073

I hope that is what it is. If not I will look for high flow aftermarket downpipes. And just have them put on when the Torque converter is replaced.
I think I will ask the seller to meet me in the middle on the Brake booster pump and o2 sensor.

[4rings2turbos]

You do have every right to tell them it's a $2k car lol.
