Audi S5 Trunk Lid Release Switchs

Audi S5 Trunk lid release switchs

Starting at $67.95, AutoBuffy stocks 1 trunk lid release switches from URO for your Audi S5. This small electrical switch signals the latch actuator to pop the trunk open when pressed. When it fails, the trunk won't open from the interior button or exterior keypad, leaving you locked out of your cargo area and unable to access luggage or a spare tire.

Signs your Audi S5 needs a new trunk lid release switch

  • Pressing the interior trunk button produces no response — trunk stays latched
  • Trunk release works intermittently, requiring multiple presses before it opens
  • Dashboard trunk-open warning light stays on even after the lid is fully closed
  • Audible click from the button but the actuator never engages or releases the latch
  • Switch feels loose, sunken, or physically broken when pressed
  • Trunk only opens via the key fob or physical key, not the cabin or bumper switch

Which trunk lid release switch should you buy for your Audi S5?

The main decision is OE-equivalent fit versus an upgraded aftermarket unit. You should also confirm whether your Audi S5 uses a standalone switch, a switch integrated into a trim panel assembly, or a combined switch cluster shared with other functions. Always match connector pin count and mounting style to your original part.

Replacing the trunk lid release switch on a Audi S5

Easy30–60 minutesTrim panel removal tool (plastic pry tool)Flathead or Phillips screwdriverMultimeter (for pre/post testing)Needle-nose pliers (for stubborn connector clips)

Begin by disconnecting the negative battery terminal, then use a trim tool to gently pry out the panel or bezel surrounding the switch. Squeeze the locking tab on the wiring connector, pull it free, and press the switch retaining clips to release it from the panel. Install the new switch by snapping it into the panel, reconnecting the harness connector until it clicks, and restoring the trim before reconnecting the battery and testing operation.

Frequently asked questions

How much does it cost to replace trunk lid release switches on a Audi S5?
Parts start at $67.95 on AutoBuffy. The switch itself is inexpensive, and most shops charge under an hour of labor. Total out-of-pocket cost is generally modest, making this one of the more affordable electrical fixes on a Audi S5.
Can a bad trunk lid release switch drain the battery on a Audi S5?
A shorted or stuck trunk lid release switch can create a parasitic draw, leaving the circuit partially powered when it should be off. If your Audi S5 battery keeps going dead overnight and the trunk light appears on, test the switch and its wiring before replacing the battery.
Can I replace the trunk lid release switch on a Audi S5 myself?
Yes — this is typically a beginner-level repair. On most vehicles the switch unclips from the trim panel and the connector pulls straight off. No special tools are usually required beyond a trim removal tool. The process takes under an hour for most S5 owners with basic mechanical comfort.
How do I test whether the trunk lid release switch is the problem on my Audi S5?
Use a multimeter set to continuity mode. Disconnect the switch connector and probe the signal terminals while pressing the button. A working switch will show continuity when depressed and open circuit when released. No continuity when pressed confirms a failed switch rather than a wiring or actuator issue.
Will any trunk lid release switch fit my Audi S5, or does it have to be model-specific?
It must match your specific Audi S5. Connector pin count, terminal layout, mounting tab positions, and button travel depth differ between makes and model years. Always cross-reference by year, make, and model before ordering to ensure the replacement switch plugs in and mounts without modification.
What else should I inspect when replacing the trunk lid release switch on a Audi S5?
Check the trunk latch actuator, the wiring harness between the switch and actuator, and any inline fuse or relay in that circuit. A corroded connector or a blown fuse can mimic a failed switch. Inspecting these components at the same time prevents a repeat repair visit.
