You're looking at the official n00b guide for the mk4 section. To cut down on stickies, I've linked all of the old stickies in this thread. **This is a work in progress** Myself, along with all the other moderators will be adding info to this thread periodically, and if you feel something isn't here that should be, please PM me.


All you need to know about:

Exterior mods Curious about different bumper setups? Want to know what a "boser" is?
Head and tail lights Looking for different light setups, or just want to know what a "Joey mod" is?
Intakes Can't decide between a cold air or short ram intake? Or want to learn about this "Swiss cheese" mod?
Exhaust systems Want to figure out which exhaust system is best for your engine? Or how about just listening to some different set ups?
Fuse list Need to find out which fuse is which? This will tell you.
Suspension All you need to know about upgrading
Wheel and Tire fitment Fitment questions? Need to know was "ET" is?
Synthetic oil vs. Regular Want to make sure you are using the right oil grade?
Diverter Valve vs. Blow Off Valve Learn why diverter valves are better for your VW than blow off valves
Stance Check out some different tire set ups and decide which size is right for your new wheels

Like what? Nothing really cheap for the 24v engine, they did such a good job engineering it there's not much to upgrade besides ecu and cams and exhaust. Now if your budget for bolt-ons is a couple-few grand then you get down to business without going turbo. 12v a little different... might be a few more options.

That's just me be disgruntled... 24v is just crazy expensive to mod and a complete N/A build is only gonna net you 240-250 hp. Only a couple ways to get above that and it's spendy.

Hey, how about a Potential Buyer/New Owner "things to look for" list? I started one in a post a couple of days ago...feel free to dig it up and use it if you like. Or I can if you like -- would I just copy and paste into a new thread? Mike

I meant something more model-specific (MK4, in my case). Like this:

Brake light switch: the correct one is green.

Hazards: if you have any problems with your hazards or turn indicators (the turn indicator relay lives inside the hazard switch), then it hasn't been done.

LATCH system: look for some stickers on the bottom of the rear seat uprights.

Other things to look for (not recalled, but upgraded):

Coolant temp sensor: new model is green (old is black);

Backup light switch (if your reverse lights don't come on and you have a manual tranny): figure out if you have the black, bolt-on-from-the-top version or
the screw in version and replace accordingly;

Clutch switches (manual tranny only, of course): there are two next to each other - if you can start your car without pressing in the clutch pedal (or you're having cruise control issues), replace them both;

Door lock module: if the courtesy light on your driver's door doesn't light up when the door is open (and the bulb is good), you may have to replace the door lock module -- there's a non-replaceable (not easily, anyway) micro-switch in the module that "tells" the car's ECM when the door is open and, when not working, all sorts of little gremlins pop up (do a search if you need to replace the module, there's been lots written about it);

Trunk lid microswitch: if the courtesy light on your trunk lid doesn't light up when it is open (and the bulb is good), you may have to replace the micro-switch on the lock mechanism;

Fan Control Module: A/C stopped working suddenly? Compressor not engaging? Most likely your FCM needs replacing: $50 online (or $200 from a dealer) and about an hour of your time.

High-mount cupholders: if yours aren't broken, don't worry -- they will be soon enough.
