    Coil Pack Swap with Pics

    Guest-only advertisement. Register or Log In now!
    First time trying to post pics here bear with me






    Tools you need: philips, flat, t25, and the rachet wrench with bit holder i got from lowes it was like $50 for set.

    remove screw holding coolant tank



    You may have to push down a little bit on the metal tabs on the firewall like so while gently picking the front of the tank up working back and forth til it comes out.



    and here


    Remove air duct by pulling up here and removeing screws, wingle it a little.


    Remove 2 screws at front of car and remove.


    Beautiful isn't it


    remove 2 screws at top of air cleaner and the air intake hose from the throttle body
    remove the air injection hose on the front by squeezing the sides of ring close to the box(its kind of odd look closely you'll figure it out)


    you only have to pull the box up about a inch to get the t25 in there or u could chance it and use pliers and the t25(screw that have u looked down in there)



    remove dipstick of course and take 2 t25 screws out
    yes the X is a bad pack


    notice the tab at the back of the plug


    First pull the plug toward the pack then gently push tab down and push away from pack(its kind of hooked in there). The first time I did this it was very cold out and it snapped right off.


    If you happen to snap 1 off just use a thin knife like this


    work them off a little at a time front to back


    Pull them all out and smash them with hammer
    or


    Bake the remaining good ones at 200deg for 30min or untill crispy and dry
    of course this is a emergency I have another 8 coming jan5 and am currently screwed for a ride.
    After going out for breakfast i returned in my 88 Lincoln with trans fluid flinging out of the torq dam near catching the car on fire so i was in a bit of a panic until i saw 2 coils in a fedex box on porch. The whole reason i bought the audi was my trans is going out, i'd say its hosed. Now if only schrodinger's cat is on my side until jan5 i'm in the clear, at least til my next bimonthly coil change.

    Here are the rest of the pics
    http://www.flickr.com/photos/33971648@N07/

    now just put the good packs in and put it all back in reverse order

    I couldn't resist tearing one open so here it is (ill try to disolve the plastic and epoxy with various chemicals later)




    Notice the poor glue job gee i wonder if water can get in that way


    Houston we have a problem
    What dumb ass designs something like this thinking its water tight
    The whole top of this should be dipped in varnish or conformal coating at the very least

    Of course not getting it wet is a good start. at first i thought i might have caused this but the guy that had the car before me must have high pressure power washed the engine weekly its show room clean and theres evidence by the marks left behind in the felt on the firewall. As I said in a previous thread i washed under the injecter rails as there was alot of sand that wouldn't vacuum up. I thought well hell if just splashed a few drops of water on these things and there gone i'm screwed. Well I only drive 2 miles to work so the engines barely warmed up by the time i get there. That with the crazy weather being single digits at night very warm by morning and raining on a daily basis during all of this had to be a perfect storm. Last week while it was parked waiting for pack i thought i saw moisture inside the windshield, well there was. I was freaking out thinking i had a leak in the roof or something then i opened the hood and everything was covered in dew, son of a bit!@ how am i going to keep this from happening(yea yea its suppose to be in a heated garage and driven only on sundays). So there I am looking at a car that looks like its been drowned, did i mention i can't even see the bulbs through the fish bowls they call lights(sighs shaking head in disbelief). Well to make a long story short there was alot of corrosion in the cylinders and on the packs this doesn't happen in a few days.

    Very helpful writeup. I am going to replace all of mine now rather than wait for a failure. I'm at 48K miles on originals.

    FYI, the headlight fogging is an easy fix, just do a search for headlight adjuster o-ring (which you will want to replace and grease up after making sure the lights are completely dry).

    that is a pretty dumb design, but after seeing how my tranny mounts are constructed (two pieces of metal with a spring in the middle held together with a piece of string) I'm not surprised.
    the B5 S4 is like the mafia... there is only one way out!

    Mechanical Catalog - 2005 - Audi - S4
    Description Qty Price Core Price Total Price
    Electrical, Ignition system, Ignition coil, Ignition coil, s4 8 $23.04

    Tax $0.00
    Shipping $34.10

    I think they should just make a kit with all the tools and packs needed and put audi logo on it. I think you'll need this way before that spare tire.
