Have you tried a gearbox reset?

 

The gearbox will not go back into 1st gear unless you stop, I have been informed (although don't get me wrong, i'm no expert) the gearbox works similar to a preselect gearbox.
when it's in 2nd gear, it has already selected 3rd, this is the reason, for that very frightening delay that can occur, when lets say, on approaching a roundabout you slow and almost stop, then floor the throttle for a quick exit, and nothing happens for a what seams to be a couple of seconds, then the engine explodes, and the acceleration is such that you go around the roundabout on 2 wheels. the gearbox controls the engine, and can't work out immediately what to do. as it's in 2nd gear, with 3rd preselected and should really be in 1st. I must state that this is my version of what has been explained to me, as I have complained about the delay in gearbox changing, and acceleration at very low speed.

What your describing is the DSG box a twin manual box with 2 clutches that preselects odd and even gears and uses one clutch per rail to swap over.These are fitted to lower torque engines on golfs etc.
The 8 speed asin box is a traditional but very advanced traditional box that is a collection of clutch plates per gear with a torque converter with internal locking clutch.
I'll upload the SSP on the asin tomorrow it's an interesting read.

 

Take control with the Tiptronic.

 

There is a SW update for the asin (mine was done at the beginning of the month) but you might get what you want from Nooby's suggestion of a GBR.
This is because the car is designed to learn your driving pattern and I expect you were nailing it about when you first got it so it now always drives like that.
As plumber says they don't go back to 1st unless as a stand still because the 1st gear us so low you virtually pull away in 2nd and the v8 has even more torque so it is never going to stay long in first..

 

Loz, What did the update do operation of the gearbox and is the update quite recent?

Loz, whilst you didn't put that document up there for me and it doesn't even apply to my Touareg, what a fantastic write up / training document and an insight to what goes on. Thank you for putting that up here for us all to see.

Great reading, but when I go for a drive later I'll be in awe of all the moving parts beneath me!

My industry is electronics, and because I know how it works I am very accepting of all the tech' in my phone, PC, sat nav' etc. But mechanical tech like this impresses me much more. Respect!

 

Many thanks Loz for putting matters right, great information, which I have saved, and sorry to the other members for getting it completely wrong, this new information though does beg the question as to why I sometimes get the problem with a quick get away when the gearbox hasn't gone back into 1st gear and I floor the throttle, nothing happens, the engine revs build slowly and then explode, I have complained to the dealer, and spoken to the Mechanic, who informed me that no fault exists, I have learned to live with the problem, which can be frightening, and dangerous. on all other occasions the gearbox changes are seamless and quick, and on kick down are, so quick it's as if the gearbox is reading my thoughts.

 

John/Plumber,

Does this happen only in D or also in Sport mode

Also does it happen when the box is cold and hot

 

I don't give the car any stick until it warms up, so I have only had it happen when it's hot and in Drive. the Dealers Mechanic did advise me to use sport mode to prevent it happening, and it hasn't happened in that mode, and I must say it doesn't always do it in Drive, it tends to occur on roundabouts, especially when a 40 ton truck has entered the roundabout and there is just enough time to get out in front of it, perhaps the car hates me ?. or it's my driving. it used to do it in traffic and I have come close to rear ending a couple of cars, but that hasn't occurred for a long time. It has never occurred if I stop, 1st gear is selected, I then floor the throttle, acceleration is then normal .
I have got wise to it and when it occurs I don't floor the throttle if I can help it,

 

I have that lag as well but I try and anticipate it and drive around it. I must try it in sport or tiptronic.

I haven't been out today so testing tomorrow.

 

Sounds like the car is being intuitive to your driving situation. You are approaching a roundabout and are either braking or off the throttle, so flooring it might induce the delay you are referring to. Knocking it into Tip or Sport would put the box on notice something different is coming. If you are still moving and not quite stationary, it seems logical that using the paddles wouldn't immediately give you 1st either

 

I can get my box to change up at lower revs by easing off the throttle and then gently squeeze back on once it has changed up.

 

As time has gone on the situation has greatly improved, the car is out of guarantee now being 3 years and 3 months old, and with under 18000 miles on the clock doesn't get used all that much, I drive a T4 van most of the time, which weighs in at over 2 tons, and with only a 1900cc engine, that has 140000 miles on the clock, all short journeys, has to be driven hard, (foot through the floor) to get it to go, so perhaps I drive the Treg the same way as I drive the van, and at times it doesn't like it to much. and if that's the only complaint I have with the car, it can't be too bad really. The Treg has got to be the best car I have had in my nearly 48 years of driving, even better than the Nissan Patrol, that it superseded, that was a great car, I loved it.
Iv'e had some bloody rubbish cars in the past, the worst one was a Toyota Space Cruiser , paid about £9000 for it in 1984 which was quite alot of money, it wouldn't pull your hat off, and to pull out of junction, the road had to be completely clear, it's a wonder that I didn't suffer a stress related illness, no resale value, so I turned it into a van and worked it to death .

 

Are you an electrician then?

 

I carry out Plumbing and heating repairs and installations, gas boiler repairs and servicing

 

I have had the first service now but there is no software update for my gearbox, (the dealer may be wrong of course) so after a GBR there is little improvement if at all in 2nd gear change up revs.

It is something I will have to put up with for the time being.

Thanks for your help though.

This post on TDI Club discusses switching off the gearbox DSP using VCDS. DSP Off

"DSP is Dynamic Shift Program - it is what learns your driving style, load conditions etc. and adjusts the shift points automatically".

I wonder if it would work on a Treg. I would assume that it can just be switched on again....

 

I'm using OBDeleven and on the transmission control unit there is a message saying new version of software is avaliable, what version do other people have on their cars and what difference is there please?
Has anyone tried changing to the Cayenne option through OBDeleven or VCDS, does it make any difference?
