At the advice of many, I decided to go in a dark alley (my driveway) and
check my plug wires this evening in an effort to combat that nasty
sputtering problem. Ummm... I think it's safe to say I need new wires! :)
When I opened the hood I saw nothing at first... but it was drizzling, and
within about 10 seconds I saw a little blue spark. Then, I took my hose
and sprinkled the wires slightly. Holy fireworks, Batman!! Sparks *all*
over the place... one of the wires had a 6" section which looked like it
probably had 50 sparks in it each time the plug fired. The wire coming out
of the ignition coil was lit up permanently.
Whoopsie... I guess this means I need new wires, huh?
Okay, I need to place my order right away... and my first thought is to
call Mark or the Potterman... *but* if anyone has any good advice that'll
help me save some money but not lose any quality, I'll take them up on it-
but you gotta act fast because I'm gonna call tomorrow (Saturday) by
lunchtime... (Gee, I hope Mark's there on Saturdays... Hmmm)
Any advice, comments, suggestions, questions?
Obviously, new plug wires are required. Stock or aftermarket, doesn't really matter.
Aftermarket uses colored wire if you want them, all use stock ends as that's the only
source of the connectors. Nology type systems are basically a ruse. Magnacor might be
worthwhile, but expensive for a tiny improvement. If you really want to improve your
ignition system (difficult as it's pretty optimized in the 16v) about the only thing
that might improve combustion is a multispark discharge system with high output coil.
Disabling the upshift indicator
So I bought another Scirocco...
I know its pretty simple to kill the light, a hammer comes
Is there anything I should be aware of when I disconnect
this puppy? Does clipping one of the leads for the LED
do bad things to something else? I'm guessing that it
doesn't. But I'd just like to make sure before I ripe the dash

Damn, it's a lot easier than that. Just go to your fuse/relay panel and
pull the relay in position 4. (It has a big 5 printed on it, now that
makes a lot of sense) It's a lot easier, and more reversible.
Ground upgrades (Weak or difficult starting)
Weak or difficult starting. Battery constantly needing recharging, or
needing replacement prematurely.
Poor grounding from engine, body, and alternator, to battery negative
terminal. Main power wire from battery positive terminal to the starter
too small or in bad condition.
The battery negative terminal goes to a ground strap that is attached to
the body(just below the airbox), and also to the engine/transmission. The
first step in fixing your problem is to make sure that all contact points
here are clean, and that the ground strap is in good shape. If the ground
strap is not in good shape, replace it. Remove the bolts that connect the
ground strap to the body, and also to the transmission. Use a wire brush,
or sandpaper to clean the ground strap terminals, and also to clean the
area on the body, and transmission so that there is no rust or paint at the
contact points. Clean the battery negative post and ground strap terminal.
Make sure the ground strap is securely fastened back down.
Now that you have gone through and made sure the existing wiring is up
to spec, you can add a few more wires to that will make the charging system
perform better than it did when it was new. First, you should add a wire
that goes directly from the negative battery terminal to the alternator
housing. There are several posts on the back edge of the housing. This wire
doesn't need to be massive, a 12-14 gauge wire should be more than adequate.
You can use a small ring terminal on the end that attaches to the alternator
housing, and a similar one to attach it to the negative battery terminal.
This is as much as I have done to my cars ground wiring, and it seems to be
enough to cure all of my previous grounding problems. Some people have gone
so far as to completely replace the ground strap with extra large wiring,
and adding additional grounding straps from the battery to the body, engine,
and elsewhere. But simply adding the one ground wire to the alternator
housing, and cleaning the contacts for the ground strap, have been enough
to fix the problems of the 3 sciroccos that I have done this on. I would
recommend doing this on any scirocco, as I have yet to see one without these
fixes that didn't at least get improved battery life from doing these
modifications. The later model cars, particularly 16Vs, seem to need this
done more so than the others.
If you still don't seem to have solved all of your starting problems, you
may want to clean the contacts on the positive battery cable that goes to
the starter. I replaced this wire with a red 4 gauge wire. Everything you
need to do this can be found at your local stereo shop. I used a custom
battery terminal that had a ring terminal for the 4 gauge wire, as well as
contacts for some additional power wires. I used these extra contacts
when I wired in relays for my headlights. Make sure you specify the battery
terminal is for the positive battery post, as the two posts have slightly
different diameters. Always crimp then solder the connectors, and use
heatshrink tubing where appropriate.
