Does anyone know if the 2012 uses a slush box or a DSG? I've been looking everywhere, but I can't find it.

I have this issue, when I move out of reverse put it in forward drive and then begin to move forward the car kind of lurches or stutters. Has anybody else experience that? It doesn't happen all the time it's just every so often like the transmission is popping into gear or busy shifting.

The Touareg does not use a DSG transmission due to the weight of the vehicle and its high towing capability would put too much stress on such a unit.

 

[Shaolo]

Hrm, I am perplexed as to why it does this then.

 

[joshpascoe]

What RPM does the Touareg idle at/shift between P/R/N/D/S ?

 

[Shaolo]

750

This is a 2012 TDI.

Hmmm... I've had this happen with other vehicles (namely trucks) but can't recall it happening in the Touareg. Does it happen on both level and slanted surfaces or does it matter? Parking brake set and released or not used at all?

I know what you're talking about. Ours does something very similar.

I have noticed a few things:

1. It seems to happen more at times, when I'm assuming that it's under regeneration and the RPM's are up in the 1000 range
2. It happens more when shift out of reverse into drive BEFORE letting the vehicle come to a complete stop
3. I have noticed that ours seems to "stutter" more than it lurches, but it has "lurched" at times as well, but lurches less, now that I try avoid number 2

We only have a few hundred miles with treg but I do recall this happening. Thought it was just part of the Touareg experience.

 

[Shaolo]

AWESOME. I'm not alone.

OK, well in that case, it really makes me wonder.

I've made a point of definitely always coming to a complete stop before putting the tranny in drive. I did this today and it still did the lurch/stutter. Only 400 miles on mine and it's kind of driving me nuts. 2009 did not do this. Honestly, this vehicle drives more like my 2008 GTI with DSG did, than the 2009 Touareg with slush box.

You sure it's not the hill holder feature you're experiencing?

 

[Shaolo]

You sure it's not the hill holder feature you're experiencing?

That's possible.

How do I test that? Can you turn hill holding on/off?

 

[CADman_ks]

Not for me. Flat as a board, LITERALLY, were I live.

2012's don't have the auto-hold feature (from what has been posted in the past), but I have never experienced this with that on. Now, it's important to realize that the use of Auto-hold in our Treg is forboten by the wife. She doesn't like it.

For me, this only happens when shifting from reverse to forward...

I find even the slightest incline or when one wheel is in a dip in the road will activate the e-brake/hill assist feature when first starting off.

The best way to figure if this is the case is after you shift into drive and take your foot off the brake, if the T is not moving, the hill assist feature is the cause, otherwise the T should move at a 3 mph pace on its own.

Sometimes the Autohold can be finicky. A few pointers.

If your experiencing clunking or lurching into gear, ensure you pull the handbrake and depress Brake fully before putting into park. I find this way, when i put it into drive then release parking brake there is no lurch or clunk.

Also if your using AUTO hold, a slight roll can confuse the auto hold feature causing a lurch where the brake will grab and let go and grab and grab. Always either come to a complete stop so the brakes can hold pressure or turn it off.

Since i've employeed these 2 steps I've never experienced a lurch or clunk.

Found this on the 6 spd tranny (our 8 is supposed to be similar). See page 25 describing how hill holder works.

The brake thing makes sense because that's what it feels like. Like the brake is catching for a split second and letting go. However, if you read the manual it says hill descent assist should never be activated on a descent less than 10*. Most of my issues are in pretty flat lots.

I don't seem to have a hold feature that can be enabled/disabled.

The parking brake is electronic, and I always put it on before taking my foot off the brake after putting the T in park.

The Aisin 0c8 transmission is superlative. It is backed by a factory 10 year 100k warranty, even if there was a trans problem your covered well into the future.

I agree that it sounds like the hill holder, or the parking brake.

From that link:

Hillholder function
The hill-holder function secures the vehicle from rolling back and permits hills to be approached comfortably.
How it works
If the control unit for the automatic gearbox detects an incline due to the driving impedance while simultaneously detecting a driving speed of ”zero”, it switches into 2nd gear.
In 2nd gear, the vehicle cannot roll back because the internal gear of the dual planetary gear set would have to turn in reverse against the locking free-wheel.

Free-wheeling is released and the vehicle starts comfortably only after the starting torque is greater than the slope descending force.

Thanks Shaolo. I couldn't figure out how to cut from a pdf.

From the same 8-speed gearbox guide (i have bolded the important bits to note):

In the Touareg 2011, the hill-holder function is undertaken by the electronic parking brake via the ABS control unit at an ATF temperature of less than approx. 10°C. At temperatures above 10°C, the function is carried out by the gearbox.​

From the Chassis and 4WD guide:

The HILL HOLD function prevents the vehicle rolling back on gradients when gears D or S are selected or when the selector is in the shifting/Tip gate. This occurs both when braking to a standstill and also when rolling to a stop on uphill slopes. This function is always active. There is no indicator for the HILL HOLD function in the dash panel insert.​

When I back down my sloping driveway first thing on the morning, and come to a stop on relatively flat road, the electronic parking brake has engaged, and does not want to let go until I have started moving forwards. No drama - just need to become accustomed to this.
