Is the T6.1 stop start dangerous

[mmcengineer]

I’m really considering getting rid of the t6.1 I purchased a couple of months ago

It seems the stop start is a bit ropey or maybe I’m doing it wrong

Two occasions now it has cut out whilst pulling out of a junction

The third time off the slip road off the m40 at junction 10 which nearly got me rear ended as I pulled off

It seems to fucnction by sensing what is in front of you if it sees a car for example turning into the junction across you and you depress the clutch it sees it as a parked car , you expect to put it into gear and accelerate from the junction and there is nothing same again on roundabouts

Pulling up to the give way lines if a car is leaving the roundabout it seems to see it for a brief second and it triggers the start stop

I’m quite happy to take the wrap but it seems a bit weird compared to every other start stop car I’ve had with no issues

Is it me or the car

Sounds like something is wrong.

It should only trigger the "stop" if you put it in neutral and take your foot off the clutch.

An option for now is to disable it with the button on the dash.

And if you want it disabled permanently there are easy fit adapters you can buy for the button - search for disable stop start on here.

As Don suggests, that doesn't sound right. Mine behaves in pretty much the same manner as any other SS equipped vehicle I've had the misfortune to drive.

I'm not a fan of SS cutting the engine and thus the oil supply to a turbo that could be spinning at significant RPM so I've formed the habit of poking the 'off' button almost automatically when I start her up.

 

[Alster]

Definitely sounds like something wrong there. Start stop only cuts in once the vehicle is stationary.

My T6 when new displayed those characteristics then would hardly pull away at an awkward up hill junction it took several attempts and the tendency to stall became worse even though it would happily just tick over and drive pulling away became almost impossible. I had to drive home to where we where staying using a lot of guile to prevent being stranded miles away . I had owned only had it a short time, 2019 146KW/199BHP T6 Caravelle Exec 4Motion, same engine as T6.1. VW Garage took it away, kept it for a short time and returned it "sorted" but it most definitely was not. A few days later they took it away again for a longer spell and evidently they had many long calls to VW Germany. It was then returned to me and this time it was sorted and has never displayed this behaviour again. No idea what the cause of the ailment was but it was cured your vehicles behaviour sounds very similar.

Agree with all the above comments, my will occasionally turn off just before i come to a complete standstill but only just and only occasionally (mine is DSG so may not be comparable to yours)

My manual T6 used to do this to me when I first got it till I realised it was me putting it into the wrong gear. Eg 3rd instead of 1st or 4th instead of 2nd.
Especially at roundabouts and T Junctions.
They stall with a bang and shudder and if you don't have stop start disabled it is harder to just turn engine back on. You lose power steering and power brakes.
Once I routinely turn off stop start and am aware of why it does it I very rarely have a problem. About once per year.
is it possible you are having the same issue I had.

 

[Sackmycook]

3rd gear doesn't have the flexibility of other engines. I regularly stalled mine at roundabouts and junctions, driving as I have been professionally taught

I thought it was me until I rolled down a hill in neutral , to a junction and it cut out at the juncture while I was braking , that’s what made me wonder if the car uses a vision system as the commonality seems to be a car in view somehow

Mines manual but I’ve never had any automatic car

I think this is the policy till I can get it disabled I find start stop more of a fad than a useful thing

and it does if crawling along on the motorway etc….. I think based on the responses I’m probably at fault but I’ll take it to dealer and ask

I also do not like stop start not good for the turbo as said and very inconvenient in the country and stop start traffic junctions roundabouts ect if they needed that environmental tool then a time switch control might have been better. I always switch my stop start off, its a habit but the problem that the OP I think needs attending too by VW Dealership if it is newish because if it is the same as my problem and they solved it

 

[whodat]

Yes - T6.1 does use the front sensor to detect when the car in front has started moving off so the StartStop starts.

Yep and bloody annoying it is too - the guy in front moves forward 3 feet and the sodding engine kicks in.

I fitted the 'cancel stop/start' device as soon as I found out that it was possible to get one and where to get a reliable one.
The only caution I would give in fitting one is to make sure the van cabling doesn't disappear down into the depths of the van. Seems it sprung back and luckily only caught on the plastic fascia with a couple mm to go before continuing it's journey to Hades.

I have that Adaptive Cruise Control that I am trying to get to grips with for 20mph roads first time I used it to see how it goes. It felt really strange allowing it to stop in traffic all on its own and then pull away again all on its own. I guess if I had not switched off stop start then possibly that would have stopped and the started also? Personally I hate automation, it is not driving, I could go down to the dole office and recruit someone if I wanted a miss Daisy Guy It was fascinating though even the bit when I drove over the top of someone only yoking!

Start/Stop sucks big time.
So much so that I ignored my intense dislike for AliEx as there is no other source. A little 12 quid cable (approx 4 inch long) that sits behind the dash button between the button and original cable that simply holds the last position. So off remains off. Installs in seconds and is set & forget. Huge 'hit' in the German Transporter community for years.

Now that made me chuckle

ACC can be very effective, but certainly not infallible - I've had to intervene on a number of occasions to prevent disaster.

My main gripe with ACC, though, is that progress can be very jerky, with constant acceleration and deceleration. Whilst this is inevitable with a system designed to react to actual hazards (rather than to anticipate developing hazards), it is very tiring and not at all fuel-efficient.
