first off i have a lot of whistling when i make boost and sometimes it falls on its face hard when i let off the pedal.ihave the apr software. no check engine lights

second where is the sunroof drain on these. my car sat in the rain windows up and the drivers rear floor was freakin soaked

third i have a slight squeeling coming from the right rear wheel. its gets faster the faster i go. the previous owner thought it had a bad abs sensor. when i got it the traction control and abs had a mind of their own so i pulled the fuses for now. what should i look into? i jacked it up and that wheel is harder to spin than the drivers side. is a brake sticking? how can u tell and how do u fix it?



i appreciate any info. thanks

 

is there somewhere else i should be asking these questions?

im good with cars but not sure where to start with this one. i always do all my own work. just need some direction here before i start tearing everything apart

 

ok you need to look in your engine bay for where your drive by wire comes out and there is a rubber seal, i think that is were your leak is comeing from. I had the same problem long time ago, if you need pics let meknow, jsut look around in the engine bay by the fire wall. as for as you falling flat for boosting got me with out looking for it or seeing a video, and the last one. it is the pad sticking, pull the whell off and pull the pads out and just reset them worked for me last week.

 

so basically just uninstall the brake pads and reinstall them?

the firewall thing i dont understand. the rear floorboard behind the drivers seat was wet not the front at all. thats why i thought maybe it was the sunroof drain.

 

Squealing from a wheel could be a wheel bearing going bad.

 

Its probally the throttle body Y Boot in-front on top of the engine or the start of another boost leak somewhere. It'salso called the TBB.. Do you hear air rushing out of a hose. Is the car not going as fast? Do you have a boost gauge? When my TBB went yesterday,thats how it started,it was violent when i let off the gas on the highway. almost like the engine mounts didn't exist.It was a large boost leak... 24 $ from dealer and worth every penny. Just do it, they tear on the bottom where you can't see it with out taking it off.

And the squealing sounds like a wheel bearing...

Does the noise go away when you turn one way or another...That Would deff be a wheel bearing, also a common problem for spirited drivers..

 

If you're going to replace your TBB, consider upgrading to something more reliable like Samco. The stock boots are pieces of $hit, not sure why Audi skimped on such an important component. It will cost more, but it's worth it. Boost leaks make your turbos work harder (not something you want to considering the K03's reliability record) and they take away that much-needed acceleration that we all love about the 2.7

Also, if you're having problems when you let of the accelerator, check into a new set of DVs as well. The stock DVs don't do well, especially if you're chipped. How many miles have you had your APR chip?

 

i had some stereo stuff put in my a4 and they forgot to put in a rubber seal to keep the water out, only the back floor board was wet, nothing in the front of the car, it runs down the interior trim and gets way back there, i bet u it is that seal in under the hood,
its right by the window on the driver side when u open the hood, small black thing, if its not there or theres a hole, theres ur problem
