Hello Toureg Owners.

Just received my new Toureg and teh Stop/Start function mystifies me. Sometimes it works. Others it does not stop the engine/
What could be the reason?
Is it to do with teh climate control?
Any suggestions?

:rolleyes::confused:
 
Yes, if the climate control is on and is calling for the compressor to run the engine won't stop.
Basically the car will continue to run if there is anything requiring it.
I've also experienced no auto stop/start after several kms of freeway driving. I assume the car wants to keep the engine going to cool it down.
There are probably other things that will inhibit auto stop/start too, Eg. low battery voltage (?).
Basically you just have to trust that the Treg knows what it is doing.

Hi momasfolly,

I have just over 2000km on my 180TDi and the start stop is beginning to annoy me...

There are a list of requirements (detailed in the manual) that are needed for the start stop to function properly, however even when I know these conditions have been met it is still a bit of a game-of-chance as to wether the start/stop will activate.

On the top right side of the MFD (in between the speedo & odometer) there is a little icon that shows when there is a fault with the stop/start, preventing it from operating.

When all is OK (and the car has switched off) the symbol is a little A with a circular arrow around it. When there is a fault (and you have come to a stop and the car has NOT switched off) the A/circular-arrow has a diagonal line through it, indicating fault/non function.

The annoying thing is the car will switch off not-one-minute after I have started it, as I pause at the nearfield garage door opener to leave the underground car park, when I KNOW the operational conditions (such as minimum engine temp) have not been met, and other times it won't work at all despite not being too hot, not having the climate control on, not having the radio on and so on.

I have a work around of sorts...when stopped in traffic, turn the system off (via the button near the drink holders) complete a few more start and stops with the system off (regular Sydney traffic will suffice), while still on the move re activate the system with the button near the drink holders and 4 out of 10 times the system will work and switch off the car when you next stop again.

Lastly, until I know more of the modifications that have been made to the engine to support this technology I am beginning to be inclined to switch it off altogether. I know the most damaging thing to an engine is constantly turning it off and re-starting it again. I am keen to know more of the systems put in place by VW to compensate for this potential rise in engine wear, e.g. is the cylinder and cam lube oil pressurised separately by electric motor and not dependent on the engine running (as 99% of motors are)

I think I will log a call with the dealership (who are nearly always rude and uninterested) detailing the fault and hopefully there will be some kind of fix for this issue.
 
Stop Start problems

Have just bought a nearly new 262ps Touareg in beautiful Canyon Grey Metallic. Anyway I sold a 4 year old Touareg SE to buy this car as I wanted a new car to keep for 2 or 3 years. Well my last Touareg was pretty much faultless but my new one has a fault that seems to have VW stumped. This crazy "stop/Start" system, that only seems to work when it feels like it has started cutting off the engine before I come to a stand still. So as I roll up to a junction at about 2 or 3 miles an hour the engine just stops, I thought this was not right as you can't have a vehicle moving with the engine not running.

I took it to my local dealer and got the usual "no fault found". So I asked for VW's customer care number which I got.
I contacted them yesterday and the not so helpful at first, advisor told me to take it to another dealer, hang on I said I've just paid the best part of 40k for a new vehicle, a new luxury vehicle, I'm not going from dealer to dealer till I find one who will take me seriously. No you, VW, will sort this out and with as little inconvenience to me as possible.
He then told me that as I haven't had the vehicle a month I can implement the 30 day money back guarantee from VW. So I e mailed the dealer who sold me the car and he was on the phone about 2 minutes later!
I've basically rejected the car and I'm just waiting for the dealer to come to some kind of "deal" or I won't be taking the car back.
The dealer has acknowledged that this is happening with other Touareg's and has agreed that it's not safe or right, especially as it didn't do it with my last car.
So I'm waiting to see what is going to happen, I will keep you posted.
 
Hi all. The auto stop is, in my opinion, not very effective on fuel saving, and is not good for the starter and battery. (Yes, it is a special battery.) To me, the feature is annoying, and I am far more comfortable driving with it disabled. But, with old age, I keep forgetting to press the button after engine start. Familiar?
So I have built and tested a simple electronic circuit that operates a relay about 8 seconds after engine start. It is powered from the accessories socket, and draws a mere 10mA. I am yet to fit it permanently, but have tried it in the car, loosely wired, for a few days, and it works a treat! 8 seconds after starting the engine, the light comes on just as if you had pressed the defeat button.
There are 2 issues for the average person.
1 is building the circuit. Any electronics guru can do it for you.
2 is connecting a wire onto the correct harness wire under the button you would press to switch off the feature. Note that you do NOT have to cut any wires. Just find the red/yellow wire in one corner of the plug under the button, and connect another small gauge wire to it.
If people are interested in using the system, and it seems many are wanting to disable it, then I am more than happy to draw the circuit and scan it to a pdf for anyone to use.
Another benefit of this system is that if, at some time, you wish to re-enable the feature, you simply press the button. After the electronics has done its thing, everything operates as normal.
Hope this helps a few people.

I am sooo glad that my "11 Treg does NOT have the stop/start feature. What a joke. Lets burn out the starter faster. IMO it's a waste of a feature. I listen to vehicles next to me at a red light do this. I think.... you better hope you don't have a failure in the system when you need it most.
 
For me it is the safety issue you imply at the end.

I have seen one minor accident and one very near miss caused by the need - quick though it is - to start the engine before the car moves.

In both cases the driver had made a misjudgement but needed their car to move bloody quickly to get out of the situation.

In other cases I have personally experienced the engine cutting out as I was coming to a stop but, when changing my mind as the road ahead cleared, I had to do a manual start on a rolling car with dead power steering!

Needless to say, stop/fart is permanently OFF!
 
G'day all.
I have read the contribution regarding the use VCDS, and my main concern is the possibility of getting the coding incorrect. There could well be the chance of catastrophic results if the coding is irretrievably stuffed up. The main problem I had with the electronic gadget I made was installing it. However, it is now installed, and it's so refreshing to not have to remember to press the button. The car behaves as if it doesn't have S/S.

The coding is easy.

As always with VCDS, you simply record what is already there in case you wish to revert, and then just make the changes as in the link I provided.

There is nothing catastrophic about it!
