Silencing the Trunk Beeper

[ciaranob]

Thanks for the tip @Tincan for the Cross Turismo. I removed my speaker tonight and replaced it with a 33ohm resistor I had lying around. The close button still works, maintaining all functionality, and no codes.

FYI, the speaker has a resistance of about 60ohm. I used some foam tape to hold the resistor in place.

Forgot to ask but have you wired the speaker plug to this resistor or did the OEM plug fit an available receiver socket on your resistor? - can’t see from angle - thx!

I put a couple bends in the leads on the resistor and they fit directly into the (female) speaker plug.

That trunk beeper was really annoying. Now I feel like Homer Simpson in awe of this door silently opening and closing and opening and closing…

if you're messing with resistors to fool the pcm you may as well try instead inserting one in series to make the speaker one third the audio level or so. don't know but you could easily play with a handful of various resistance to sort out which is best. maybe around.. 10Ω to start. in series in one of the wires. *shrug*

Took the time to muffle the speaker with foam so it's only half as loud. It's much more bearable now. Thanks for posting the location of the speaker!

I also found how many retaining clips are missing / not installed after my roof repair. Slowly eliminating rattles after the roof repair.

For anyone who wants to see the end to end process. From removing the trunk liner to replacing the speaker with a resistor.

Awesome video. Thanks! Would you mind sharing where you sourced the resisters and pry bar?

Amazon or local hardware store.
I had a trim removal tool left from installing a dashcam, but search for "Auto trim removal" on Amazon, and you'll find plenty of options for about $5.
Resistor. Look for "60 ohm resistor ceramic", again either on Amazon, or at your local HW store for a couple of $. 60ohms is the speaker resistance, but replacement does not have to be exact at all. It is mostly to not leave the circuit open, which prevents the inside close button to work.

I unplugged the speaker over two years ago & reading this post helped me realize that's why my inside trunk close button doesn't work. Thank you!

With a PIWIS, disable this. it will disable the beeper. I couldn't find anything to adjust volume or count of beeps.

I just did this speaker removal yesterday. I followed the video's example with 2 50 ohm resistors wired together. The trunk would not close from the screen. I assume this comes down to a software difference, because 2 x 50 ohms worked for him, but not for me. Since the speaker is 60 ohms, 2 resistors is 100 ohms and that's apparently too much. I extended the wire lead on one side of the resistor and plugged that into the speaker harness, for a total of 50 ohms - much closer to 60 ohms. This worked. I'm sharing this for anyone else who ran into this issue. It's a very simple fix to extend the wire and the silent trunk is so nice.

this is a very old thread, and I likely responded to it years ago (don't feel like reading through all the pages of responses)... My dealership(s) have done away with the rear-hatch opening-and-closing beeping noise for me in three of my Porsches at no cost. So it can be done, and it's not a safety issue tied to some law that would cause them concern or pause. They may just be lazy if they refuse to do it.

 

[bigkraig]

since we are updating, i have probably had the thing hit me or someone else on the head more than 5 times since turning the beeping off.

a small price to pay for the obnoxious sound
