First, Everytime I start up my car i have to hear and look at my engine light on ( MAF sensor) and hear that god awful beeping noise that beeps three times cause the car is saying my abs is out and the abs light is on while the brake light flashes. Well first off my ABS is not out cause this happens on and off and supposivley your rear brakes will lock up and my brakes work fine. Does anyone know how to fix this problem or where i can get a new sensor so it stops SCREAMING AT ME! and does anyone know where I can get a new MAF sensor for cheap cause I don't like engine lights. My next question is I think my bearings on my front tires are going bad. Everytime I turn a corner i hear like a noise that a skateboard bearing would make if it was old and rusty. So does anyone know how many bearings are per wheel and all that jazz and how much they are? Now my last and final question, I want to repaint my inner rim wheel caps before I get new rims, just so they look nice until i grab some new kicks for summer. So does anyone know how tho properly get the Audi symbols off without breaking them. I see the tabs in the back but wanted to know if I should heat gun it or something before poking and pushing. Thanks guys!!!

 

Can no one help me out on such issues

 

Check out this website to buy your bearings

To install:

For your MAF:

Also, you can check Ebay for a MAF and pick one up for $32.99 - $59.99 shipped,
but its Ebay and that's at your own risk. Just type in A4 MAF and a bunch will pop up.

As far as your screaming beeps...someone else can back me up on this, but the first thing you should do is VAG it and see exactly whats going on with it. It's an expensive fix so you should be sure exactly what it is before you start dropping some coin. I'm not too good yet with VAG...maybe check ross-tech's website.

If you do need to replace the sensor, here's how:

Lastly, as far as your wheel caps go, if it can be snapped together, most of the time it can be taken apart. Use some common sense and take your time...don't rush to failure. I haven't personally removed the emblems, but I would just watch out breaking clips (if there is any) or if its glue, just follow the DIY for emblem removing and you should be fine:

Another alternative to painting them that I've seen some guys do is this:

Kinda cool if you ask me. Anyway, I hope this helps you out. Good luck brother!

 

Are you talking about the little round grey caps in the center of the wheels? They pop out, trust me you won't break them, if you could I'd have done it already lol. If you've got somethin soft to pry them out with, you can get 'em off without removing the wheels. Maybe like a tongue depressor or popsicle stick? I wouldn't use a screwdriver or something like that, definitely gonna scratch up yer wheels that way. The way i've taken them off in the past is to remove the wheel and pop them out from behind with yer finger. Seems like Joe did a pretty good job answering your other questions, so thats my $.02

 

Thanks guys that helps alot. Yeah I figured out how to get the caps off now I wanna get the emblems off without breaking them and repaint it then put the emblems back on till I get some new kicks.
