Not a huge issue (that i'm aware of anyways) but, it's always bothered me that there's a buzzing noise coming from behind the binnacle during start-up that lasts for a while...

I could speculate for a while in many directions (brake servo, abs block, electrical gremlins, solar flares) but thought i'd ask in the forum here if anyone else experiences this, knows what it is and/or knows of a fix...

kind of a whining buzzing...

will get vidya soon posted up if i can

 

you have an 04 which i will assume has secondary air, it is probably the pump on the fire wall, passenger side.
i believe they run for a few minutes on start up

 

I have the same noise, without secondary air. I've always assumed it's one of the many pumps priming ready for start up. I've noticed it, tried to see where it's coming from, but until something stops working, I'm going to ignore it.

 

Haha I knew it wasn't just me! I have an 04 with secondary air. The secondary air sounds like a shop vac. This sounds much different. Idk what it is though because I have had my D2 since new and it has always made that noise.

 

Where exactly? Literally behind? Left? Right? I believe there is a small fan in the dash, lower left above fuse door.

 

Binnacle? As in the overhead compass housing?

Not sure, but maybe you are hearing that little fan mounted in the dash (lower left side of the steering wheel)?? I have no clue what purpose it serves... An air exchanger of sorts?? Draws fresh cooler air into the fuse block?

Over the course of three weeks or so my fan has increasingly become more audible.

 

That little fan is part of the HVAC system. It meters the cabin air temp. It's probably got a dust bunny living in the fan. I suggest removing it, and cleaning it. Noise should quiet down after you clean it.

 

Over time a number of members have asked about the whirring sound coming from behind the dash to the right (In RHD cars will be from left for LHDs) of the steering wheel below binical, here to be exact.

Behind the grill this fan is fitted

While it will never be absolutely quiet you can help by giving it a clean. this will also make it operate better as the temp sensor will be more effective if clean.

1. Open the fuse access panel below the steering wheel and you will be able to see the fan unit. (bear in mind that yours will be the opposite hand as mine is RHD)

2.Remove the unit by taking out two screws, one show above. Not the one in focus, but the other to the left.

Now the extent of dust contamination can be seen. This is mildly dirty, I've seen others that were completely clogged with dirt.

3. The unit can be opened and dismantled by removing the remaining two screws and the components cleaned

4. Nice and clean ready to reassemble and refit.

Thanks for the write up there @Alphamale - hoping to pop it out today and take a look. will post back the results...

 

You're welcome, hope you have small dexterous hands, otherwise it's a pig to get at the top screw.
