    P3 Vent Gauge Install Woes

    Guest-only advertisement. Register or Log In now!
    Assuming I'm not the only one who's ever had to deal with the exploding vent slats while installing a P3 gauge. The vent electric cable doesn't detach on the B8.5 like it does on the B8, so you are stuck working on this while the vent is dangling in the car. What is seemingly a 30 minute ordeal can easily become a rage inducing multi-day exercise in not throwing plastic trim parts down the garbage disposal .

    So noob-tip: If your vent slats fall out and you have to reinstall the little metal connecting pieces, then use small pieces of masking tape to affix the metal connector to the vent slat pivot points. It took a couple attempts for me, and the only pic I have is from a preliminary attempt, but the idea is to use a very small strand of tape to loop around the metal and plastic pivot so as to prevent the metal piece from falling off. Once all 3 slats are seated in the vent and you've locked them in with the chrome trim outline, cut half of each loop with an x-acto knife and pull out the tape with some pliers.

    Would have done this too: drill a large hole out of the vent assembly and feed the cord through that instead of through the back. If paranoid, then figure out some kind of rubber boot that you can put to prevent air from entering the fusebox area. Not that I really care about adjusting the vent, but the cord has pretty much removed all movement of the slats (which was the whole point of reassembling correctly ). At this point, I couldn't care less, as I never want to touch that thing again.

    Pic is pretty much worthless, but included since I took it:

    My shop, GMP Performance in Charlotte NC had to use an older A4 P3 application in my B 8.5. Call 704-525-4946 , ext 256, Stephen. I'd think he'd talk to you about it. He knew of the problem and ordered the older kit for me. You'd think P3 would know it too?

    Any chance you can post the info in this thread?

    What do you mean older P3 gauge? I don't believe there's any new gauge for the facelift. Only issue might be a slightly different installation process. A B8 installation could have the same problem with the vents falling out or the cord getting in the way afterwards.

    Drob, all I know was he told me he had to use a P3 gauge for an A4. Honestly I'm not certain anymore. Call the man up or e-mail him, [email protected]. Mine went in with no problems, of course a tech did it. They did a tremendous amount of work on my car, I'd hope they would talk or write anybody with a problem such as this. Invoke my user name, Skywagon...they know who I am.

    Had mine explode on me as well when pulling the trim piece off. Luckily mine is a B8 and vent can easily be removed from the car. Getting that metal connector piece in place on the top three slats was a pain. The metal piece for the bottom 3 slats fell somewhere into my dash...luckily I don't need it anymore with the P3 gauge in place...

    The A4 is pretty much the same car when it comes to trim. Maybe a couple of extra badges and bling here and there...but the interior and S-line exterior trim are all the same (minus the rear diffuser). And the B8 to B8.5 differences are minimal, but they exist. Usually you find out when following a DIY because they are subtle but head scratching for noobs like myself.

    Had a couple of questions for you about the P3 gauge after finding this post.

    Would buying the completely assembled OEM vent unit P3cars sells make any difference at reducing the complexity of the install? Especially in relation to the B8.5?

    Do you have any experience using the available analog boost sensor with this unit? Is that something that would work in conjunction, say, with the boost tap kit that ECS (and others) sells and you commented on in the other thread?

    Thanks.

    I've installed a P3 in my dad's VW and we got it with the OEM vent. Took literally 5 minutes to install and was super easy.

    I do not think P3 offers the gauge and vent combo for the B8.5, or at least they did not when I bought my gauge.

    Dunno. On their website here: http://www.p3cars.com/audi-a4-s4-a5-...tal-interface/ when selecting options, it allows you to pick all the way up to MY2014 for your car with the pre-installed OEM vent option. Unless they didn't actually ever check that, but it doesn't say anything special in regards to B8.5 on there..

    I had the entire package, vent and gauge installed. I was told the trim for the 2014 B 8.5 does not match the B 8.5. An A4 package was installed easily.

    Almost the same thing happened to me when i installed it on my GTI. Afterwards i didn't even care about it anymore. The thing that kills it for me about this gauge is the fact that it only shows "requested boost" and is not actual boost.

    @Skywagon
    I saw you make mention of that, but from the limited pictures I can't make out what difference there might be as far as the vent itself is concerned. I wish there was a side-by-side comparo that might make it obvious.

    This is kinda what I was asking about in my second question. AFAICT if you get the analog boost sensor with the P3, and combine that with any one of the myriad boost tap kits out there, it can read and show actual boost numbers instead of relying on the ECU, but I was just hoping someone with experience with it could confirm or not..

    Yes it does unlike the reading from the OBD port only. I'm using the AWE tap.

    I don't understand why you'd want a boost gauge. If it's just for giggles that's fine, but do you use that information in any other way? Isn't our boost directly tied to RPM?

    Why do you want any gauge? For monitoring if nothing else. And if you are going to have one why not have it be accurate?

    Seems like everyone answered your questions. Definitely worth the extra effort to do the boost tap imo.

    So I just ordered the P3 Gauge this afternoon, for the sole purpose of avoiding the boost tap and its related maintenance/issues. It's upsetting that it reads requested boost and not actual, I may go with a different.. and cheaper product now, not sure.

    What maintenance issues with the boost tap? It just sits there after being installed providing a port to get a boost/vacuum measurement from, or?

    It's a wet line that comes with a filter and there was a PSA not too long ago about filters being clogged up/issues.

    The filters are $2 at autozone. We'll see how often they need to be replaced but I'm not worried.

    Are there different locations to tap from? Trying to figure out why mine is dry when I check it. Maybe I do not have enough miles on it yet (23k)?
