Tapping Noise - Anybody Else?

Pretty often when I start my car in the morning or when it has been sitting for a while I can hear a tapping / knocking noise.

It seems to come from the passenger front/central console front. Eventually the noise goes.

I have had it into the dealer but they couldn't find anything wrong with it (although I wouldn't be surprised it they didn't look for the noise)

By the way it is a 2.5 TDI (05 plate).

Has anybody else had a similar problem?

P.S. Posted this on the General Forum by mistake! (Edit: moved)

Hi,

Can you describe the noise at all - it could well be the AC actuators/servos operated - the VW/AUDI system does a system check to ensure all the air circs door are closed - this sounds more like a quiet click every second or so

This sounds very much like the auxilliary heater noise that has been discussed a few times...although I wouldn't have expected you to hear it at this time of the year :shock:

The Treg has a heater that helps to get the car heating warm quicker in cold temperatures. It can give a "tick, tick, tick" sound and eminates from the centre console/passenger footwell area. It's the same device that can keep running for a few minutes when you switch off after a short journey and fumes can still keep issuing from underneath the car after you have switched off. It's caused one or two panics as well :wink:

I do recall reading that there is a fix and some on here have taken that up.

Here is one link to an older thread: Linky

Thanks.

It can be described as a click, click, click.

You can hear it more in the colder weather although I heard it a few weeks ago in reasonable weather.

It sounds as it it could be it. It is annoying. It can make a noise for > 5 mins and can be quite loud at times.

Thanks for the replies. I will take it up with my local dealer.

Hi there, my 2.5 53 does this also. To be honest I've not been too concerned about it. I think it's something to do with the air conditioning system.

If you keep turning the fan speed down until the passenger temp display says Off does the sound stop?

I'd say it could still be the HVAC (AC) actuators over driving - this is actually part of the programming logic, HOWEVER you do get a big variation in the small motors themselves - some are louder than others - getting them rejected as part of a warranty claim will be a matter of the dealers attitude. I know for a fact that they do get returned due to this noise as in the past I spent many hours in a acoustic chamber listening to them with the suppliers arguing over noises we can and cant hear :roll:

I'd plump for the Aux Heater - It was still ticking away in mine at the end of April

There is a fix under warantee but you may have to push and it's something I've never got round to sorting - but don't worry, yer car won't self destruct in 10 seconds.... :shock:

I'm due to take it to Holland next month.

I need new wipers anyway so I will speak to the dealer.

The noise can be quite loud. I do turn the heating off etc to test but it still does it

Although it does stop eventually.

Thanks guys.

I will probably miss it if it ever goes :wink:

Local dealer was aware of the issue and has just fitted a "modification kit to the auxilliary heater pipes". Was carried our under warranty.

Thanks TT.

Hi everyone,
It looks like my Treg (2005 - V10) has developed this ticking noise. I'd had noticed it before, but it was particular obvious this morning when I moved the car after clearing all the snow on it.

The car is no longer under warranty, hence I am trying to figure out a) whether it matters if I leave it as it is,

how much it would cost to fix it.

I can't emphasise enough how brilliant this forum is - many thanks to all for their useful contributions.

Best,

Romain

Hi,

My 2.5 Diesel does this as well.
I have a warranty from the supplying dealer (not a VW agent) so I took the car back with a copy of "touareg techys" post about this being a well known fault.
My dealer contacted the local VW agent who denied all knowledge and said that the few cars they had seen with this problem were fixed by putting packing around the pipework!
I subsequntialy contacted Volkswagen Luxury Cars and today have had an email saying that they are to contact their local dealer to ascertain what is wrong.
If as it would appear, this is truly a well known fault with a documented mod to fix it someone at VW and or its dealership is not telling the truth.

It will be VW, I have the same issue on the noisy wipers............

Update, email received from VW this morning.

"I have spoken to *****************, Service Manager at Hadwins of Lindale to investigate the comments raised in your email. He has advised that his service department had a conversation with the Independent Garage who you had bought the vehicle from. He explained that checks were carried out using your vehicle identification number, also known as your chassis to see if there were any known faults with your Volkswagen Touareg. The report has identified that there is no known fault.
Unfortunately, websites and forums cannot be used as a source of our information as the comments are those of personal opinion and not factual information. Paul has explained that you will need to visit the retailer for them to look into the fault to confirm this is the area of concern. They will then discuss what will need to be done to rectify the problem.
I apologise that I am not able to provide you with any further information at this time."

Now is this a known problem or not???

Vehicle is no longer under VW warranty but I have a warranty with the supplying dealer.
So it looks as if I will need to pay VW to check a documented problem so that I can claim under the suppliers warranty.

It's a known problem.
Known to those who own and or drive a Touareg,but apparently not to VW.
The fact that many forum members have the problem is ,according to VW ,just hearsay.
No wonder this country is t*ts up.

That to me sounds like factual information to me!!

Goblakers

Can we have the name of the dealer for shipbuilder to contact (location dependant!!)

Shipbuilder

This could be the dealer being snobby due to the fact that you didn't purchase the Treg from them IMHO!!??

There, thats my 2p worth, feel better now.

Hope it gets sorted

It would be worth looking at the 90D7 thread in General Discussion. Seven pages of useful stuff. Aux heater fuel line is part of that fix and it should be free of charge even outside of warranty.

Cheers, Andy
