New Beetle 98-02 Disable (DRL's) Daytime Running Lights - TFL Pin Method

In this article, we're going to cover the simple procedure to disable your factory DRL's (Daytime Running Lights). NOTE: This procedure does not work on some 1998 and 2002 VW's - requires relay modification (posted after this article)

ools needed for this Mod:
Electrical Tape
Scissors
20 minutes labor time

The first step in this procedure is to remove your light switch from the dash panel. Simply push-in the switch approximately 1/8" and turn clockwise (picture below left). Once the switch begins turning (your switch may go into the "ON" position), release pressure and pull the switch back towards you (picture below right). If the switch does not release from the panel, try pushing-in and turning again. The removal should not require much force on your behalf.

Once the switch and wiring harness slide out, make sure your switch is in the OFF position. To disconnect the harness from the switch, locate the "squeeze clips" on each side of the plastic harness piece. Squeeze both clips while sliding the harness piece off of the back of the light switch assembly (this will require moderate force the first time). Now your light switch assembly should be disconnected. Now, flip the switch assembly upside-down so you're looking at the back (where the harness plugs-in)...

Examine the connecting pins on the light switch, making sure that the text/numbers you see are right-side-up. On the top row, 3rd pin from the right, should be marked as TFL below the pin (picture above - red circular highlight for illustration purposes only).

Now you're going to cut a small piece of electrical tape, relative to the width of the TFL pin we've identified. Take the piece of tape you've cut and cover the TFL pin, so there is no exposed metal showing that might make contact with the harness plug (pictured below). Some modders choose to bend-down this pin (achieving same result), but we do not recommend this. Using this method, you can re-enable the DRL's by simply removing the tape.

Once your switch is ready, simply reverse the removal process to re-install. Once you have the switch connected to the harness, check to see if your DRL's have been disabled (remember that key must be in the ON position with parking brake OFF). If you're satisfied with the mod results, simply slide your switch assembly straight back into the dash opening until it clicks. You're done!

New Beetle 98-02 Disable (DRL's) Daytime Running Lights - Relay 173 Method

In this article, we're going to cover the procedure for modifying the 173 Relay disabling the DRL's (Daytime Running Lights) on 2002 NB's, as well as certain 1998 NB's where the TFL Pin modification does not work. Refer to the TFL Pin Article for other model years.

The first step in this procedure is to remove your light switch from the lower dashpanel over the driver's pedals. Move your driver's seat back as far as it will go to give yourself room to work. In the pictures below, we've pointed-out where the torx screw are located to remove the dashpanel.

There are 3 T-20 torx screws located under the dash trim panel that need to be removed to drop the panel. NOTE: Turbo Models Only: With the front of the panel down, disconnect the Turbo Spoiler deployment switch harness from the switch mount. (picture below - right) The rear of the panel is held in place by 2 white clips - once the screws are removed, slide the panel towards you to remove (you will then see the white clips mounted to the firewall).

With the panel completely removed, you will now be able to visualize the relay blocks under the dash. Use the Vag-Com Connector as your landmark - looking up from the floor, locate Relay #173 (see picture below). Once located, unplug the relay from the block.

Once you have Relay #173 removed, you will need to open the relay housing with your small flathead screwdriver by wedging the head into the bottom panel where the connecting pins are located (picture below - right). Carefully remove the panel from the housing.

With the relay cover removed, locate the contact that we will be working with (picture below - left). Cut a small piece of electrical that you will insulate the contact with.

Use the piece of tape to cover the conact. Before you snap the cover back on, plug in the relay and check to ensure your emergency Brake Light is working in your instrument cluster and that the DRL's are disabled.

(EDITORS NOTE - I have found this BugMod photo inaccurate - the tape should not go ontop as shown...it should go between the contact that moves to the right of the switch...this insulates the contact from occuring. See last two images for propper installation)

Once you're sure that the process is complete, replace the relay cover and plug the relay back in into the block. Simply reverse the procedure for replacing the lower dash panel. You're done!

Another note:

The Cheat
Quote:
On the 98s, 02s, and 03-up, you can tape the "B" pin down to disable the DRLs without taking the relay apart.

Please add the following to the end of the "disable DRL" how-to. (There's no discussion)

Following a LOT of posts concerning the 173 relay, this statement is confusing.

Fact, is the "B" post is on the headlight switch (not the relay) and is indeed IMHO the preferred solution for those models where the TFL post mod doesn't work.

It was pretty obvvious on my '03 that that mod wouldn't work, as there's no wire in the wiring harness to the TFL post.

Simply, put, on cars like mine the "B" post is the solution.

As for the relay mod, it all seems like too much.

It should be so much simpler to just pull the relay, and if you're concerned about losing the parking brake warning light, simply make a jumper wire to connect terminals 85 and G at the relay mount to continue the ground signal to the instrument cluster.

Still, why even do that when the headlight B post is the solution?

Finally, FWIW, I simply removed the female "B" connector from the headlight switch harness rather than taping the terminal. Put a little tape around it to avoid any potential shorting.

I do this for people all the time and all I do is take out a small screw driver on my leatherman and fold down the B pin if the TFL method doesn't work. No shorts takes 1 second and instant gratification.
