Do I need a VAG-Com?

Hello, looking for some insights on this.

I live in NW Arkansas, without an Audi Dealership anywhere near home (120+ miles, Tulsa, OK). I've recently had the CEL come on and tested the car with the OBDII reader, resulting in the following codes:

P0491, P0492 and P0444.

I beleived these were all related the Secondary Air Injection system. I checked the fuse and relay in the Ebox (plenum chamber) and they were OK. Also checked the vaccum hose on top left side of the engine, -which was unplugged- and plugged it in and secured it in place with a clip.

Then proceeded to erase the codes and went out for a drive. Nothing showed up for a full day, and then, this morning after driving to work, the CEL showed up again. Checked again with the OBDII and got the P0491 & 92 fault codes.

I think I'm going to dive deeper into this to solve it if I want the CEL to be gone for good.

Also, after I changed my CV Boots, the ABS - Traction Control lights started to show up on a random basis (every now and then...)

Should I get the Ross-Tech or settle for the OBDII Reader? (The OBD I have is not mine, so no need to pay for that).
Also, should I get a Bentley repair manual, or is there something similar available from Ross-Tech?

The car is a 2001 A6 V8.

Thanks in advance.

Yes. But my opinion is admittedly biased! :-)

We also offer the Bentley manuals on CD at a substantial discount to our customers.

I recommend getting it and the manual as well. I think the Ross-Tech version of the VAG COM is worth the $229 he is asking.

What other things can be done with it?

I've heard I could program the Key fob with it, as well as other things...

Also, can the tiptronic transmision be reprogrammed with it? Does this require any special mechanical or computer skills? (Bear in mind, I can sometimes feel challenged by an XBox...)

Thanks,
