First of all, what year and engine is your car. This is important. I'll go through the codes anyhow:

1 - check the vacuum line to the combi valve (metal can at back of the head). If the line looks good, you have to start checking components. Vag-com would be very helpful for that.

2 - Looks like you'll need a rear O2 sensor. Around 100 bucks plus installation. Try clearing the code and seeing how long it stays off.

3 - Not sure on this one. What year is the car? I'd check the vacuum lines to the brake booster first. I think that code is referring to the vacuum pump and pressure sensor that the very late B5's had for the brake booster. Again clear it and see if it comes back.

2001, eh? I'm quite interested in the 3rd code. You got PM.

In which case walky is spot on with the diagnosing steps. Lucky for you, the rear O2 for the AWM (2001) is on sale for 53% off. Install isn't terribly as you can access it from under the car. Click here for a replacement downstream oxygen sensor (http://www.ecstuning.com/Audi-B5_A4-Quattro-1.8T/Engine/Emission/Oxygen_Sensor/ES8367/?salesrep=CArmbruster&utm_source=audizine&utm_medium=forum&utm_content=CArmbruster&utm_campaign=postreply).

For your other options, I too would start by checking the vacuum lines going to the brake booster and going to the combi valve as walky has mentioned.

I got a list from dealer:

Bank 1 Sensor 2 Oxygen Sensor--replace the Part
Crank Case Breather Hose Cracked---Replace tube, housing, valve, seal, clip
Can you guys tell me the price for the parts and labor?
Really appreciate your help and time.
Thank you so much!

Yeah, I can get you a price for everything but this is absolutely a DIY fix for all this. The hardest part is the Oxygen sensor, which is only hard because you have to go under the car for it. Are you sure you don't want to tackle these yourself and save 100+ dollars? Not to mention buying the parts at the dealer will cost more too!

Can you offer me the price of the parts and parts number in details?
And, are there any guys can tell me how serious about the problems? Are these problems really dangerous and need to fix immediately? or I don't have to fix that?
What if I don't fix these problems, what gonna happen?
I may not to fix that by myself, so can you tell me how much for the labor usually?
Hope to hear from you guys soon.
Thanks!

Tips for replacing the combi valve (http://forums.audiworld.com/showthread.php?p=2337540) - as you can see pretty easy to get to.
Tips for replacing the breather hose (http://www.audizine.com/forum/showthread.php/323826-pcv-prv-breather-tube?highlight=broken%20breather).
Tips for rear oxygen sensor replacement (http://www.audizine.com/forum/archive/index.php/t-246876.html).

All these fixes are important to the functionality of the car. You might be able to skip the rear o2 sensor but you won't pass emissions controls if you do - and it is a cheap and easy fix. The others are serious.

Problem: Car has loss of power, feels like it is slipping.

I paid Audi $145 to diagnose my 2003 A4 cabriolet B6 1.8L 88K miles.

Audi got an error code 17887 P1479 008. The audi dealer quoted me $3,800 to perform a long list of repairs. He quoted $727 to replace brake vacuum pump and I got him down to $482 so that is the only repair I am authorizing.

I do not intend to make any repairs myself. I joined this website to check on pricing and to see if I can protect myself from getting taken over the coals (which happens when they see a lady).
