2006 B6 V6 3.2L Passat 4-motion timing chain issue please help

[zerohour117]

Hello

I own a 2006 B6 3.2L 4 motion Passat and it is making a lot of noise coming from the engine bay. The sound is a rattle type sound like pebbles in a bucket and is also making another noise (constant sound, loudest sound heard in video) that sounds like the chain is hitting against something. Sometimes I also here a ticking sound in the car. I have only recently noticed this and a few times I have heard it around 10 metres away. The car is a bit more shaky when driving and at times it judders when it is stopped.

I have uploaded two youtube videos showing the noise:

The noise gets noisier the longer I drive the car I think. Please have a look at the video and let me know what you think? I am pretty sure I didn't notice this much noise or anywhere near this much noise before. It sounds like a tractor or some kind of very noisy diesel engine.

Thanks

Because it is a 2006 model, the links below may help, i believe there was a problem with the bolt holding the sprocket that connected the crankshaft timing chain to the overhead cam chain working loose, it can cause major problems if it brakes, sorry for the bad news, but better have it checked out. Not sure if you can still have it fixed as good will from VW's, has I believe it to be a common problem on the 2006 Passats. Peter.

Yep, get it looked at as soon as possible.

Also, does it go away once the car has been running for a bit?

Did you manage to take a look at the videos I posted on youtube? Does the sound coming from the engine sound normal or not normal?

Thanks again

It doesn't go away, it gets worse if I drive the car for longer I think. But definitely it doesn't go away. I drove for 1 hour this morning, 1 hour this afternoon back home and the noise is still there. After the 1 hour of driving to work, it was a little bit noisier to the point I can hear it 5-10 metres away. How likely is it the timing chain?

[zerohour117]

Is this problem more likely to occur in lower or higher mileage?

[Umai Naa!!]

Seems to happen to a certain age range, up til MY10, from memory when they changed the chain tensioner design.

[zerohour117]

Does my problem in the video I provided relate to a exhaust leak?

Have you had the car looked at?

+1 ^^^^^^^

Could it be noisy HLAs? Have you had the oil changed regularly? They can get quite noisy if they become clogged, not something you should ignore.... I certainly would *not* drive my car with that kind of noise emanating from the bonnet.

[zerohour117]

My car has always been serviced on time and followed the servicing schedule. It has about 90,000 km on it. I am going to get it looked at soon, I haven't got the time because I got work. But is this noise normal for this car? I am sure I haven't heard this noise before. I opened the bonnet and checked the engine, it seems the noise is coming from the back of the engine where the timing chain is located. Should I be concerned?

[zerohour117]

And the ticking noise doesn't go away. It stays and can get quite loud if driving for long periods of time. (1 hour at least)

[brad]

yes, you should be concerned.

Timing chain is on the left IIRC.

What do you mean by serviced "on time & following service schedule"? If your in Sydney traffic & lots of short trips then every possibly you need more frequent oil changes.

Where do you get it serviced?

Originally the car was serviced at VW dealership. The last two services were done at EuroHaus, European specialist for car servicing. The ticking, sounds very similar to this noise in this video - https://www.youtube.com/watch?v=jXtHDM1kovU and this - https://www.youtube.com/watch?v=KgHDWMF19-M and this - https://www.youtube.com/watch?v=EeO3-2vknPQ.

It doesn't go away the sound. One of the videos I have taken is after 1 hour of driving. The other one is just starting the car. The sound gets louder if driving for longer I think. I opened the bonnet of the car, a bit hard to tell where the sound is coming from exactly but it sounds like those youtube videos.

What do you think it is likely?
