<b>6. What's a BPV? What's a BOV? BOV vs. BPV? Is a BOV a good mod?</b>
A BPV is a Bypass Valve.
A BOV is a Blow Off Valve.
A BOV vents excess pressure generated b/w shifts to the atmosphere, thus purging the air OUT of the intake tract. A BPV RECIRCULATES the purged air and keeps IN the intake tract.
For the purpose of the A4 1.8T, utilizing a BOV is <b>NOT</b> a good idea as it will cause a rich condition (i.e. less air to fuel ratio) and cause damage to the cat, soot on the exhaust pipes, occasional misfiring due to the loss of the purged air, etc.

<b>9. What bulbs are used for lows, highs, and fog lights?</b>
For 99 and earlier: H7, H7, H1

<b>10. What are Euro-spec Housings? Headlight upgrade options?</b>
Euro-spec housings are housings that have clear corners w/out the amber insert, contains city lights, and has bulb covers over the turn signals.

If you have 99.5+ <b>OEM halogen</b>, you can get Euro housings with the clear corners and it will fit stock bulbs. You can also upgrade to aftermarket Xenons and it will work with stock OEM housings or the Euro projector housings.

If you have 2000+ <b>OEM Xenons</b>, you <b>HAVE</b> to get the Euro S4 Xenon housings as the A4 Euro projector housings will <b>NOT</b> accept the OEM Xenon bulb.

If you have the two piece headlights, you can upgrade to aftermarket Euro two-piece system from <a href="http://www.lltek.com">Lltek</a> that can be bought with HID or not or go the 99.5+ route with some minor fender triming.

For those of you on a budget, there are other options available other than getting Euro Housings as an upgrade. For example, if you are a 99 and earlier A4 owner and want a one piece conversion headlight system, you can acquire a used set of 99.5+ headlight housing and install w/ some minor fender trimming as it utilizes the some blub size. From that, you can upgrade to aftermarket Xenons and it will work w/ OEM one piece halogen housings. <b>HOWEVER, YOU MUST PURCHASE HOUSINGS FROM SOMEONE THAT DIDN'T HAVE OEM XENONS.</b> OEM Xenon housings are made for OEM Xenon systems. For you 99.5+ people, you can just upgrade to aftermarket Xenons that can be purchase listed below.

<b>11. Which chip is best?</b>
They are all good. To date, the favs are GIAC and APR w/ a few followers from MTM and ABT and Wett. The recommendation is going with a local tuner in case of unseen problems that may arise from chipping. Also, check <a href="http://www.audiport.com/survey/survey-main.htm">this</a> out.

<b>WARNING!</b> You may encounter warranty issues by chipping. If a problem occurs and can possibly be tied by the addition of an aftermarket chip, get ready for some serious trouble about getting the repairs done under warranty. <b>CHIPPING CAN VOID YOUR WARRANTY.</b> This is not meant to scare you. Just to inform you.

<b>12. What to consider when doing a K04 Upgrade?</b>
<a href="http://www.europeanspeed.com/k04.htm">Read this...</a>

<b>13. Will RS4 bumpers fit?</b>

<b>14. Will S4 brakes fit?</b>
No.

<b>15. What is the hidden EQ? How do I access it?</b>
The hidden EQ is a hidden graphic equilizer found in the SYMPHONY head units.

<b>17. How do I change the spark plugs?</b>
For 2000 and earlier:

1) Remove engine-cover plastic shroud.
2) You'll then see the four coil-packs. There are two allen-head bolts holding the coil-packs in. Loosen the two bolts and pull the coil-pack up and out of the hole.

4) Installation is the reverse of removal.

Torque specs for changing plugs

Plugs: 22 ft-lbs

<b>18. Where to get boost gauge for cheap? Where do I tap it?</b>
You can get a gauge for cheap from <a href="http://www.summitracing.com">Summit Racing</a> or <a href="http://www.turboimports.com">Turbo Imports</a>. Another option it to the the boost gauge kit from <a href="http://www.awe-tuning.com">AWE</a> or the A-pillar boost gauge kit from <a href="http://www.supremepowerparts.com">SPP</a>.
There are two places you can tap it. One is the Fuel pressure regulator at the back of the engine bay or the line that runs off the intake manifold towards the wastegate check valve at the front of the car. See this <a href="https://www.audiworld.com/tech/elec48.shtml">link</a> for more details.

<b>19. When I turn on the A/C, a visible vapor accompanied by an unpleasant odor. Is this normal? How do I get rid of the smell?</b>
It's normal. It's simply the air condensing when the water content in the air comes in contact w/ the cold air.
If you haven't been using your A/C much, some fungal residue may build. Possible solution is to the turn up the heat on the A/C and have it blasting to kill the bacteria that resides in your A/C vent system.

Another suggestion is to turn your A/C off (i.e. leave the fan on but hit ECON to turn the compressor off) for the last 10-15 minutes of your trip. This allows the A/C components (duct-work, etc.) to warm up and for the condensation that forms on them to dry off (since there is still airflow 'cause you are still driving). This will limit the bacteria growth. It is especially important to do if you are going to be leaving your car parked for any length of time and/or it is humid out (more humidity = more condensation).

Another possible solution is to change your pollen filter every 10K.

<b>20. How do I get that little panel off above the center console where the cupholder and fog buttons reside for 99.5+ cars?</b>
Can pull it off or pry off using a teeny tiny screwdriver. Just be careful not to scratch your interior trim.

<b>21. What gives the 2001 1.8T more power? What's VVT?</b>
Lower compression, higher stock boost levels compared to 2000 and earlier MY, and VVT.
VVT is Variable Valve Timing. It changes the timing of the intake cam using a phase actuator on the chain connecting the intake and exhaust cams.

<b>22. My center cluster, trip computer, LCD display on my guage cluster went out. Is there a fix?</b>
Hit the reset button on the underside of of wiper stalk (right stalk) to turn the trip computer on/off.

<b>23. How do I remove the front bumper??</b>
<a href="http://www.127th.com/audi/mods/aprsnub.html">Read this...</a>

<b>24. How do I post multiple pics in one post?</b>
Enter this command w/ the pic URL in the "Message" box:

&lt;img src="http://www.the_location_of_your_pic.com/your_pic_name_01.jpeg"&gt;

&lt;img src="http://www.the_location_of_your_pic.com/your_pic_name_02.jpeg"&gt;

&lt;img src="http://www.the_location_of_your_pic.com/your_pic_name_03.jpeg"&gt;

<b>25. Should I upgrade my BPV if I chip? Which one is best?</b>
Recommended as chip might cause your OEM BPV to fail and leak boost.
The commonly used ones are Bailey and Forge w/ some running a Turbo XS BPV. There is also the cheaper alternative; the stock TT BPV: Audi PN# 06A-145-710-N

<b>26. Should I put "Xenon" like bulbs on my car? Where can I get them?</b>
Read <a href="http://lighting.mbz.org/tech/info/bulbs/blue/">this</a> first.
You can get them at your local tuner shop or from <a href="http://www.supremepowerparts.com">SPP</a>.

<b>27. Do I need to upgrade anything else if I chip? Can I go with just a chip?</b>
Recommend to upgrade the BPV. Why? See #25.
Yes.

Bryce

That's for Newbies. What about us old addicts?

Sal R.

...please correct me if I'm wrong.

Waseem

I think you might need a newbie FAQ for yourself bro, you're not right on everything

Sal R.

...this is meant to help out newcomers.

Waseem

I'd include a link to the site that answers ques
about blue bulbs or Xenon filled H7's, and
maybe a little advice on upgrading to higher
than 55W bulbs, and the advice would be not to
do it. I can send you picks of why it should not
be done.. I still have my old H7's that were 70W
bulbs.. ran em for a year.. they don't look pretty.

This is a great idea! Good job so far Sal.
