Golf/GTI VI :: 2011 - Grinding Sound Around 2k RPM / Diverter Valve?
Jan 25, 2012
I currently have a 2011 DSG. I purchased it last year and when I test drove it I did not notice any unusual sounds coming from the motor/ drivetrain. However since then I have noticed that the car makes a grinding like sound when my car is around 2k-3k rpms, its especially loud under load. Its a very audible sound, like something is grinding in the transmission- Everyone that has been in my car can hear it, and it only happens at low rpms. Anyway, I took my car in once to service and I mentioned it, however the tech said he could not hear anything.
I honestly think that I got louder since then so I took it back and the shop foreman came out for a drive with me. So the guy hears the sound, but says that its the diverter valve and that its supposed to sound that way. He tells me its because the cars now have a metal valve and that its louder. I had a 2002 A4 1.8t and it never made a sound like that, even after chipped. So Im a little worried that its something else and I wont be able to get it fixed under warranty, or maybe im just paronoid and the DSG sounds like this.

Where is this diverter valve located at ? Is it under the car?

Having issues with the stock one that came with our cars I think I may be leaking from the diverter valve. I was searching the forum but couldn't find the answer but when I hit the gas I can hear I would say like the diverter valve is constantly releasing the air and the power pretty much plateaus doesn't keep pulling like it did I'm assuming the diverter valve because i know there were issues of them before but i wasn't sure if they had the same issue in the mk6.

So the other day I replaced my N75 valve and upgraded my DV to the Forge 007. For some reason the turbo doesn't spool like it did before, it's lost it's pep.
I've tried the Yellow and Green springs, also I tried them with the shim too. No luck. The car got turbo back exhaust, intake, and stage one program.

The CEL on my Passat came on. When I scanned it with VAG-COM, the following fault code was displayed:
000665 - Boost Pressure Regulation
P0299 - 002 - Control Range Not Reached
The car also felt like it lost its power in some way, especially when the turbo kicked in. So after some research, I found out that the Diverter Valve was causing this issue. Rubber diaphragm on original valve was made from rubber and was torn. I replaced it with upgraded valve and wow what a difference!!! Very easy to do, great write up link below.

If your diverter valve is bad, will it throw a CEL or not always? I don't have a CEL but sometimes I feel like there is a lag in the boost. Wondering if the diverter valve is bad or not.

Was cruising on the freeway and all of a sudden my exhaust sounded like it has a leak!!! I gave it some gas and it got louder but the car didn't pull like normal??? No check engine light or anything crazy. I don't think the inter cooler pipes blew off because the engine didn't shut down and I was on cruise mode.
Its sounds like the turbo wants to spool but cant hold boost, can this be the diverter valve leaking or its blown?? I haven't had the chance to check which diverter PN# I have but Im pretty sure its the stock OLD version. I am the 3rd owner. 07 Passat FSi variant with 36K miles.
I hear the 07 FSi are know to have bad or weak Diverters.... I know I needed to go with a stonger TSi Diverter which I hope is the problem here....

We have changed the brakes and the caliper on the right passenger side of our 2008 Hyundai Elantra. When we brake, we a getting a grinding sound. We had to change out the caliper 2x before we got a working one. Now with a working caliper, we are still getting getting the loud grinding sound. We had greased and removed all rust in and around the caliper. The brakes are new.

Just got this vr6 a week ago and noticed what sounds like a valve clicking, I thought maybe it was low on oil or something, so I just changed the oil and filter yesterday, clicking was gone from what i could hear. Start up today to go to work, clicking is back, I've noticed after the engine heats up the clicking subsides, but when you first start up I'm hearing it tick in the same area. Thinking maybe a intake/fuel cleaner next? My other 24v never did this. I've never taken it over 3k or anything until after it's warmed up.

It started a couple months back, under about 20 mph I feel/hear a rubbing or grinding sound. Appears to be coming from the front end, I put I on a rack and drove it but couldn't isolate a cause. I rotated the tires, replaced the brakes to be sure there was no warping. Everything looks good, but something clearly isn't.

So... I bought Ksport Coilovers and had them installed about a month ago. Were on the car about a week and started to get creaking noises from the front. So, I contacted BSH (who sold them) who put me in contact with the Director of Operations for Ksport...
Send them to him, and he replies that he thinks my sway bar is high, and that it should be "parallel with the ground. Today when backing up (down right) I get a horrible scraping grinding sound. I stop, get out (thinking it is the fender liner) only to find no damage. So I keep checking and find a fresh scrape on the axle. I drive (gingerly) home and pull the wheels off and check everything in the front. It is all tight and nothing seems to be broken. I look at the sway bar end (which is curved).

So its been about 2 months since this grinding sound started whenever Im going under 40km/h on my Mk IV Jetta.
Brake pads/rotors that is causing this or something else?
There is a metal/rubber friction smell when I park and get out of the car... It also drifts to the right a little and the alignment was done about 6months ago. I'm guessing its related to the rear breaks or I could be wrong?

My 01 Jetta 2.0 recently started making a grinding sound on start up! had the crank sensor and the starter changed about a month ago and everything was fine but yesterday, for absolutely no reason it would make a horrible grinding sound on start up.Not the typical one where the engine starts and 2 seconds later it screeches (I searched) but while the engine is turning over it grinds. Once it didn't turn over at all just grinding sound. It's not all the time tho either?

New GTI with PP. Less than 400 miles. When I brake at low speeds, I can hear the sound of the pads and rotors rubbing, bringing the car to a stop. It's a light grind/rub sound. Nothing disturbing - just not silent. Is this normal? Perhaps just the brakes and rotors breaking in?

So I noticed some grinding noises in my Mk IV VR6 the other day... checked my PS Reservoir and it was empty. Topped it up with some Pentosin, then 3 days later it was dry again. Looked underneath the car and the steering racks were drenched...

Got the stabilizer bar recall done in February and have been on a couple of long trips since then. No real issues until about a week ago I noticed at low speed, when turning left, and usually if there was a small bump or incline........like turning into my driveway, there would be a popping/grinding sound. It could happen at speed, but never heard anything. I go last night to install some ECS cross drilled and slotted rotors and flush spacer kit and noticed this on the left front....
Well honestly I noticed first that I needed to wash my car, just got back from the beach and it has been raining here, but is this installed correctly. The bar is bent near the top, easier to see in person and I am fairly positive this is not correct. Called the dealership and they are going to check it out Monda. The picture below is of a left front on a MK7 and it appears to be the correct.

So yet I found out about another common issue but not that publicized. This is the grinding sound when turning at full lock (left or right) in slow speed. I've read several people in the forum who has encountered this. I read different remedies but the most common one is to have the CV boots lubricated.
I have a 2014 Wolfsburg with almost 5k miles. I am really now worrying about my water pump crapping out on me but I heard this grinding sound yesterday.

My 2003 Jetta GLI was making a terrible grinding/knocking noise when i would turn and occasionally make this "Bong" sound especially when reversing. I took it to my local shop and they say my spring in the front left is "either broken or unattached" and that i need spings/struts. I have like 150k miles on this car so the timing is probably right. So my question is, how much should they charge for this? Also, what should i have them order and install? Im not trying to lower or anything like that, OEM or a slight upgrade is what im looking for....

My '11 Golf speaker sound has become tinny lately. I don't play high volume music. Really annoying, especially since I have less than 18000 on the car.

I purchased a 2011 GTI on Tuesday. Loving it so far. I've got a question about a noise I hear though. It is at 1500 rpm. It sounds like high pressure air, kind of a pshhhhh sound (like letting air out of a tire). It isn't loud and there's no impact on performance. I assume this is just the turbo spooling up or something related to that? This is my first car with a turbo so just want to be sure .

My 2011 Golf with the 2.5 has developed a rapid chirping sound at 55-60 mph, that varies in rapidity as I decelerate from 60 mph. Doesn't do it at lower or higher speeds. It isn't terribly loud, but noticeable. Only have a little over 24,000 miles on it.
