Has anyone else noticed this sound at idle speed, hot engine (2.0FSI GTI), if you stand outside your car you can hear what sounds like ringing bells, chriplike resonance. Seems to to coming from the area right near the alternator. Of course it doesn't do it all the time. Noticed it in my car, and a friend's GTI too.
I've recorded it with my cell phone voice recorded, sounds louder than it actually is in person See WAV link here, this sound can be heard starting at about the 4 second mark onward.

Anyone else hears this? What is it??

Thanks

I haven't heard anything like that. Not even when starting from a cold start at -25 degrees C. Your engine sounds kinda funny.

I know this is not want you want to hear but the sond of that is BAD. I dont know what it is but i have seen about 30 MKV's now and none of them sound like that and my MKV is not makeing that noise and i asked around in the car club i am in and they all dont here that to.

i hear wierd noises 2. toke it in while when i first noticed it. dealers said it was normal engine break in. get it check out though. it's free anywho

I have the same problem, a clicking sound that seems to come from under the dash. I took it to the dealership and they said it was a problem with the car, and that they are trying to find a part to fix it.

Hey there fellow GTI owners. Keep in mind that the MKV has direct fuel injection (same technology used in diesel engines) therefore we have a fuel pump in the engine compartment which makes some noises which you may not have heard in other vehicles which run with unleaded fuel. FYI (The FSI motor runs with fuel preasures well over 1000psi and our injectors a good upto 3000psi) Not bad for a stock fuel system..

 

[Mr. Spool]

The purpose of direct injection..........better efficiency and quicker throttle response?

Ok, given all that...but do you do hear a similar resonace that fades in and out?
Keep in mind that the linked recording in the original message is an exageration since I literally recorded it over the alternator region with the hood up.

Thanks.

There's a Christopher Walken joke to be made here, but I'm not touching it...

mine makes strange noises at idle as well... sort of sounds almost like a grinding sound though... not a chirp.... it seems like it only happens when the car is at idle or the throttle is BARELY depressed...

Of course, it is difficult to hear right now because the jackasses at my dealership have STILL, after more than 6 f'ing weeks, not fixed the fuel line rattle associated with the TSB. Apparently, the fuel line insulator is on back-order.

I'll tell you what, between the radio problems, and the fuel line rattle, and the dash vent rattles, and this strange grinding noise, I am not too satisfied with VW right now. I am driving a brand new car that cost me close to $30K and it rattles like a f'ing tin can. My 1999 328i with 75K miles that I sold to buy this GTI didn't have any of these quality problems... and it was an 8 year old car!

 

[kingpin]

im having similar problems to marcian. there are clicks and rattles coming from under the hood and in the dash. Any way to fix this?

I also noticed that my fast makes the same "cowbell sound", but it's intermittent and seems to quiet down the longer I let the car idle on its cool-down. There is also a "cloppety" sound that accompanies it, but it's soft and doesn't sound like metal fighting metal or anything even serious. It's most likely normal sounds, I've never had a vehicle that didn't make some strange little sound.

YES, it does seem to quite down the more the car rests, especially after some highway driving. The "cloppety" sound is normal for this engine, its the bells I'm not too sure about.

Have you heard my recording? Can you record and post your own sound clip to compare??

 

[Ecoterragaia]

I am sorry, I don't really have any way to record it digitally. The sound is very faint and I only noticed it after reading about your problem. Even if I did have a way to record it, I think that the normal idle noise would overcome the "ringing" sound anyway. I had a 1992 Camaro that made a similar sound (though a lot louder) and it seemed to me that it was attributed to the idler pulley. I noticed that the idler pulley is underneath the alternator on this car and that's where it sounds like the noise is coming from. In a general sense, I would say that a ringing noise doesn't indicate something wrong with the engine as it can only be created by an open piece of metal, something that isn't attached to something else by very much. Most moving parts of the engine are pretty well attached or are muffled by fluids. I don't think it is anything to worry about, it's just very annoying cause it makes your car sound less quality.

This is a recording from another member posted on VWVORTEX showing the same problem. Is it more or less like yours and mine (see WAV file in original 1st posting) Click here

 

[Ecoterragaia]

No, the noise in mine sounds more like your clip. That recording from the other post sounds REALLY loud and is much more constant. The sound in mine is more like a "dinga dinga ding . . . pause . . . dinga ding . . . pause . . . ding . . ." I will try to record it on my phone tonight, but like I said, it's very faint and seems to disappear after about a minute at idle speed, so my phone may not pick it up at all. The reason I said I couldn't record it in any way was because I have no idea how to transfer a video recording from my cell to the computer. I don't have a data cable and my IR port only allows me to download things to my phone, not upload them.

MLT06, for some reason I cannot attach my recording to a post (it says that it is not writable), but I can email directly to you. The sound seemed to come out in the recording, which surprised me. Maybe you can post it if/after I email it to you. Let me know what you find out . . .

Thanks, it sound like mine, you can hear it towards the start and end of your recording. I will host the file for you, <Click here>
