Just what you need before xmas, an accident.

I've left the VW passat stationary in a car park, i've got Auto Hold assist in it, the car park is hard to explain, its a gravel/dirt based road and has very slight gradual gradiant then slopes down gradually for a while. When i'd left it, i'd got something out the boot it was fine, i'd had thought i'd see the car moving if i'd got out myself. So at this point the car was probably at the point where weight sustained it enough not to see it roll back.

I returned back to to my car (Manual transmission) and it's then rolled off into a wood fence, with just the bumper damaged. This is going to be a insurance claim and new bumper, so luckily nobody involved or injured and no other cars hit just a residential fence where it ended up!

Reason i'm posting on here is for some community help.

I am pulling my hair out trying to understand whats happened and whether this really was just me being a pillock and to blame for assuming and not being vigilant that the car wasn't in handbrake mode.

The last week or so the Auto Hold has been playing me about and not coming on when I press the button to activate it, could this be a manufacture fault to blame? I've read a lot about people hitting issues with Hill hold.

Can anyone help my sanity with this???

You got out of a car and did not apply the handbrake and/or out it in gear and you are trying to blame the manufacturer?

The auto hold feature is not designed to be used when parking, it is an aid for pull away when driving.

I’m afraid this one is your problem.

So you knew that the handbrake was playing up and you still left a car on a slope and not in gear?

Your fault.


I may be slightly biter on this though. I got my car back yesterday after having it damaged (wing/headlamp/bumper) by someone who failed to park securely on a slope.

I don't understand how people can park on a slope and not leave the car in gear (or park if auto)

I was asking if it was...not if i had a case.

Lots of people have posted about issues with it not engaging. And i found this;

The car was fine when I pulled up got stuff out the boot then walked away, i can only think it was only slightly moving for me not to see.

What happened here was you got out of a car on a slope, without applying the handbrake, it's not surprising it ended up in a fence. Just lucky it didn't mow down a child!

So was it an electronic parking brake that was used or a hill hold? Did you operate it as per handbook?

Auto hold isn't a feature for use at journey end when exiting the vehicle (the manual electronic parking brake is).
It's a convenience feature for during the journey (in lieu of using the manual electronic parking brake feature).

That article talks about auto-hold and parking brake as if they're the same thing, but they're not.

My missus has a Tiguan with both but it's an auto so we don't use them (other than manually using the parking brake if the car is on a slope).

How does it work if left to its own devices - I suspect the parking brake maybe comes on when you turn the ignition off - did you leave the keys in?

More of a sensible answer Im looking for, to be honest the more it sinks in the more it adds up, i've gone from auto to manual and i guess on manual its different.

Appears some posters on this thread have never made a mistake, so I hope you know how to deal with one when you eventually do!

I think the giveaway is the name 'auto hold assist' - it's there to assist you by holding the car on a hill so you don't roll back as you come off the brakes to pull away. It's not designed as a substitute handbrake any more than cruise control is designed for you to get into the back seat and shag the missus while doing 70 on the motorway.

At most it will probably be coded to hold the brakes for a few seconds until a throttle input is detected. Its clearly not designed to hold the car in neutral while you get out the car.

Operator error, next time don't be a berk and use the PARKING brake.

I thought auto hold was a feature during driving to prevent the car rolling back when performing a hill start. Systems I’ve used normally disengage after a few seconds, useful so you can still roll back if required.

ETA - auto hold and hill assist are 2 different things. If it is auto hold I am surprised it let go.

The obligatory "think of the children" post.

Once again I am obliged to ask....would it not have mattered if it had hit an adult? Is it ok to kill or injure them? Why do only children matter?

The feature itself works on the same principle in either an auto vehicle or manual.
It's just if you put it in Park with your auto box the drive train is locked anyway. In a manual you'll have to leave it in gear to achieve the same effect.

Auto hold should automatically apply when you come to a stop & release when you press the throttle. Like I say though I've always believed it's a convenience substitute for during the journey, not a substitute for electronic parking brake at end of journey.

OP, lot of assumptions on this thread... did you apply and handbrake and/or park it in gear?

If you applied the handbrake then it could be the rear discs cooling and letting the handbrake off, very common with skoda Octavia.

See thread on the exact incident:

335d auto has the hill hold linked to footbrake (engages all the time footbrake is pressed up to two minutes, disengaged as accelerator is pressed). Transmission goes into P when: engine switched off (button stop/start), when driver's seat belt is undone when stationary, or when driver's door is opened, and has a manual parking brake lever. Finally, the driver has to decide if wheels need turning into kerb.

They have a potentially longer tax contribution period ahead of them.

I think auto-hold should apply the parking brake itself when the engine is off - although as we don't use it in our car I can't remember the exact MO. I'm pretty sure in ours you can drive off with the parking brake on and it auto-releases - maybe you have to do that for it to auto-apply again.

It was confusion over how it all interacts that caused us to just turn it off. In an auto car it's not needed anyway, other than to manually apply the parking brake when needed.
