My 2005 touareg has the same problem when I bought. Went to the Vw dealer and they said do a transmission flash. After that, I notice the difference. Getting better a lot. But, sometimes, still..when it's heavy load, and down shift from 5 to 4, I can still feel the transmission shock.

The 5th to 4th THUMP is a very common fault.

You need a new valve chest.

Do a search for "valve chest" but it is also referred to as "valve body".

The gearbox reset you can do for yourself:

Turn the ignition but do NOT start the car.

Press the accelerator firmly to the floor and hold it there for a full 10 seconds.

Turn the ignition off and remove the key.

The car will now learn how you drive it.

It is worth doing this on a regular basis especially if the type of motoring changes from, say, lots of city/town work to open roads.

Thanks for your reply l d not know the gearbox could be re-flashed, l will speak to the dealer and ask if they think a re-flash might help Cheers

 

valve body maybe ?? What ever you do you are covered by the Aust lemon laws i would insist they get it seen to straight away (diagnostics etc etc ) and rectify the problem ..... NOW.

No stuffing around these laws are there to protect you and if you dont get it done its money out of your pocket

Where is Nooby when you need him .... how long till the valve body usually goes ??

Mine was shot when i bought the vehicle at 155k got it done straight away ... but then again you have a T3

I do believe what you have said makes a lot of senses, going back to the dealer now is the best way to avoid what might turn out to be expensive, l'll post how l go with this,, and the way l get treated by the dealer cheers.

 

Good time (while you are in the mood) to go over the vehicle to see what else could be wrong with it which the dealer would have to fork out for. I also had the auto rain sensor not working but they pulled the wool over my eyes with that one. Wasn't till later when i got the windscreen replace that the guy told me the gel pad from the sensor was missing therefore making the sensor useless. Wish i knew that before i would have been able to take the dealer over the coals on that one as faulty and therefore a safety risk. Would have stood up with the ACCC i reckon also.

 

I have done a gearbox reset recently and noticed quite an improvement on the way it drives.
I am only having a small issue where it does not kick in the turbo early on steep climbs when I really want to get over the hill quickly.

 

A transmission reset together with a ATF drain can make the worlds difference on our cars. I will be doing the 3 rd drain soon, all within about 3 months. Shifting improved noticeably.

 

wow that seems to be a lot of ATF going throw the box, hoping that is not what needs to be done regularly,, anyway l did a reset and it seems to be a bit better but l have not driven far so lll see how this goes now.

 

After 3 drains most of the original ATF should be gone.

 

Anybody tried 'Revmax' updated valve body on their V10 yet?

 

I completed the 3rd ATF drain today, here are a few pics mainly of the tools you need for the job.

 

I have the same problem, just got a Touareg 2008 V8 with 46k miles on it. Did you solved this problem already?
