Few issues i need help with!

[AudiA4Turbo22]

Well guys i finally fixed my annoying sunroof rattle, and a few other things, but i got a few more things that are killing me!!!!

1.) When i turn on my A/C i have both sides set to 68 degrees, mind u it's over 90 out, and when its on full blast the passenger side vent in the center and near the door give out hot air, both are set to the same temp, and i've tried setting the right one to a lower temp no use! temp sensor??

2.) i have a custom exhaust, and every time i come to a stop i hear the metallic bing noise constantly at a stop, not normal like when u shut the car off, i mean like when i come to a stop light i hear it!

3.) I have this surging issue and it's driving me nuts, my boost sometimes feels as if it's not there! I've changed my N75, MAF, Injectors, u name it!!! I changed y 710N DV last week!!! Last time i took it to my Audi tech he said that ur boost doesn't feel like it's always there because he thinks the o2 sensors are shot! is this right???

4.) i need a tan armrest cover, and a battery cover!

EDIT!!!!!!!!!!!!!!!!
5.) i just changed to an optima red top battery, and now every freakin time i start my car after it sits for a few hours my average fuel consumption thing resets itself and this gets annoying! anyone know what it is, feels like i fried the hard drive!

6.) My alarm doesn't beep anymore when i lock it, and when i push the panic button all that happens is the lights flash no sound!

7.)my sunroof when tilted open whistles seems normal, but it's pretty annoying, and even when it's closed it whistles a bit!

8.) my average VAC pressure is 18 is that normal for APR 1+??
TIA everyone!

The vents in the A4 sound like servo operated units, so maybe the servo operating the baffle for hot/cold selection went out on that side? If by chance they're vacuum operated, cracked vac lines are always a possibility.

Anything rolling around in your trunk by chance?

Mine has an odd surge feel to it sometimes too. It got better when I swapped out the N75, but still annoying when it happens. I'm thinking about going the MBC/EBC route to see if taking the N75 out of the picture helps.

4.) i need a tan armrest cover, and a battery cover!

1. The air vent flap servo motor is probably faulty.

2. You need to realign the exhaust system according to the Bentley when cold, so that when it is hot, it doesn't ground out when expanded/hot.

3. For surging, try installing the DV reverse from stock orientation, so that boost pressure is applied at the center/bottom port and the DV discharges to the tip via the side port.

thanx guys i'll get right on the servos and crap, but ya i have the 710N reverse mounted, and when u say have the exhaust realigned, basically it has to sit straight?? well i'll take it back to the muffler shop and have them fix it!

how did u get rid of your sunroof noise? was yours the rubber seal around it? if so, what did u do?

[AudiA4Turbo22]

^^ no actually if u tilt urs open u'll see this flap right underneath the glass towards the back it moves up and down, it's supposed to keep water from going inside! if u push on it u'll hear the rattling and u can see Audi put some felt there but it doesn't work stick ur hand in and u'll feel the hinges that hit the metal part of ur headliner, i put some felt there and thats it!

Do you have an intercooler? You mentioned the weather was 90 degress out in socal. I understand with a stage 1+ setup, you are more likely to heat soak, thus maybe you arent getting the full power of it. I know this because I am pretty much the same set up as you, and can def feel a difference when its hot outside. Thats when I baby my car.

^^oh ya no doubt but it does it when it's cold out as well! so can the sensors be the cause????????

If the O2 sensors are weak, or faulty, that would be evident from the lambda correction values shown in VAG-
COM, and there would probably be one or more O2 sensor fault codes stored, but it's possible they are just slow responding due to age. Do you have vag-com? If you have an OBDII interface cable, you could use Lemmiwinks to increase the fuel a little bit for high loads, that could reduce or eliminate the surging if the fuel ratio is weak from the aged O2 sensors or other reasons. You said your DV is reversed, are you sure it's connected so that the boosted air is IN to the DV by the center bottom port, and discharging to the turbo inlet hose via the side port? If you aren't running a stock DV, you should install a OE DV for troubleshooting purposes at least.

You may need a new rubber seal around the sunroof window.

It may just be a cooincidence, but the alarm horn has died for some reason. Sometimes, when the battery goes dead or is disconnected, various system controllers can get misconfigured, if you have a vag-com, check the comfort module coding, that is how the alarm beeps and parking light flashing is selected with lock/unlock alarm activation/deactivation.
