E86 3.0Si Sound Generator Missing?

Post by Matt_3.0Si » Fri Jan 19, 2018 9:01 pm

Just been under my dashboard to finally do the sound generator mod on my 3.0Si (I've only owned it for 3 years!) and was surprised and a bit gutted to find nothing but a hole where I expected the noise inlet pipe to be :|

Further investigation under the bonnet showed that I lack a sound generator. I have a resonator box of some sort after the filtered air inlet attaches to the throttle body, but there seems to be nowhere on that box to mount a pipe to the cockpit. I do however have a gaping hole in my firewall where that pipe is supposed to go.

Anyone ever heard of this before? I thought the sound generator was standard on the 3.0Si from what I've read? Off to eBay I go! :roll:

Yep, standard. Must have been removed by previous owner, cant really fall off by itself.

Sounds like just the pipe with the foam inserts is missing - It's probably been taken out by someone to remove a foam, and they've not put it back in place properly. If you don't know the "knack" the cabin end can be a bitch to get in properly and sealed.

Bloody hell, that was quick, cheers! :thumbsup:

#9 is definitely missing, and I'm not sure about #6 (I'm assuming that's the diaphragm that amplifies the sound before it goes down the tube). It's raining now, but will have a proper look in the daylight tomorrow. That's incredibly helpful though, nice one!

Well, just been to have a look under the bonnet in the daylight, and it looks like some absolute weapon has removed the whole sound generator assembly. I have two bolt holes where I’m assuming it should mount. What a ballache :headbang:

Mike, please can you describe this 'knack'? I don't think I've ever managed to get it back in place properly.

Lol. I found the easiest way to do it was to pull the end ring off the pipe, for that to the body and then slide the pipe in.

Hi, I should think that if the pipe’s actually through the bulkhead you’re going to hear something? :?

Mike is long gone from this forum but as per the smartest bear in town’s reply above. It is part 6 that generates the sound, the pipe merely directs it into the passenger footwell area.
