How do you replace the turn signal-flasher relay on a 2001 Volkswagen Passat?

The turn signal flasher relay is incorporated into the emergency flasher switch on the center of the dash near the radio.

Pry off the switch cap, it clips in to the switch body and releases fairly easily. In any case you are about to remove the switch which the cap clips too, so no need to be careful with it. I found that prying upwards with a thin screwdriver released the cap easily. Don't pry against the 'wood' trim.

You will see a black rectangular rim with a red LED(push it and see) mounted in the center. Grasp the rim of the switch with a pair of pliers and pull it out of the dash. It should come fairly easily.

Unplug the connector from the back, plug the new switch in to the connector and push it back in to the dash.

The new relay is available at VW dealer for $30
