Well my incidents of the epb releasing in neutral was never accepted or confirmed by VW, VWFS. As it was a company car they waited till the lease ran out and just before my VOSA/DFT complaint deadline. Was promised it be investigated but car was sold onto car giant.

Theres three videos of it was happening fairly regular felt like once a week.

Hello @PisstNBroke, I have a lot of videos of my car doing the same.
It is a vw golf vii, and when you release the clutch in neutral, there are some times the parking brake disconected itself.
It is a nightmare and VW says nothig about it .
In an official VW workshop they told me that my car was the only one in Spain with this issue, and a few days later they told me that nothing happened to the car.
I feel powerless because of the attitude of the brand with this problem

I have an official guarantee of the brand and it is useless

....when I had a manual golf with autohold it engaged the handbrake auto hold automatically when I depressed the brake or switched off the motor
So which one - handbrake or autohold? They're very different things.
The vw posted in the video has both.

If he switches off the car with autohold on the hand brake comes on automatically. (Red)

If you press the brake pedal it will auto hold (green) when you lift the clutch the auto hold comes off.

You need to put the handbrake on manually if you want to dick about with the clutch.

The procedure you should use is.

Stop with foot on brake.
Neutral foot off of clutch.
Remove foot from brake ( green light will be on)
Switch off engine (light will go red)

It shouldn't release by touching the clutch alone.

Slightly confused here
Is there one button to enter auto hold and another to put the handbrake on
Or is autohold the thing that automatically releases the handbrake
Should it be called auto -release


Either way you can see why when pulling away on hill starts it might think it useful to release the handbrake when you take your foot off the clutch

If autohold (which works by holding the footbrake on) is switched on then the handbrake works automatically. But you can also use the handbrake "manually".

Not sure what's happening in the recent poster's case, but for one thing you have to press the clutch to start the engine in a VW manual, so you don't want the hadbrake releasing at the same time!

The Car on the video is in neutral gear, ignition on.
It releases itself only touching clutch pedal ( when you raise your foot )

VW SAYS IT IS NORMAL

when did the green hand/ parking brake light change to red?

In that video auto hold is on when the handbrake is applied so the autohold function may release the hand brake when you let go the clutch
If you have auto hold switched off is the handbrake ok?

Not sure if I’m misunderstanding this.

Auto hold was on. Why would you depress and lift the clutch if you’re not in gear and planning to move?

I’ve nearly been caught out by the auto hold turning off when I accidentally VERY lightly touched the clutch and began to roll back - but I put it down to driver error rather than design flaw.

Sorry about mi English, I'm from Spain.
The problem is very simple, to start the engine the car forces you to press the clutch, and then when you release it the epb releases itself

A lever you easily pull and push a button to release is a bit different to a ridiculous sometimes automatic/sometimes not (depending on how the car feels at the time) parking brake/auto handbrake.

Try again...
I find the electronic parking brake much better than a manual one. I certainly could live without it but I prefer it as it is seamless and is one less step in the process, particularly the auto hold function which means you don't have to keep your foot on the brake pedal. I can't see any downsides assuming it's reliable of course...

The system should only release the brake with a gear engaged, never in neutral

Ok lets not get hot around the collar here. This scenario happened.

Unlocked car and got in.
Car already in neutral, press clutch down and press engine on button.
Bring clutch back up not interfering with anything else the handbrake is automatically released and so car rolls.

Ok my driveway has a slight slope very minor, but all I wanted to do at 6am on a cold weekday morning is de-ice my car.

I got told from VW techs to do it this way, that way and every other way and it still did it. It was intermittent, always worried whether it will hold at your next stop, one day it was doing it all the way into London on the A2. Im sure you can appreciate filming everything your doing from the driving seat isn't the easiest of tasks especially when it's just happened so your hoping it's going to redo the fault.

Also VW admitted a similar issue with the Q2, T-Roc, Karoq and Alteca? They blamed it in temperature differences interfering with the selector sensor.
Its only an issue with manual gearbox with EPB. The cure was to look for a response on the throttle pedal as other manufacturers do. But in my instance and the other persons video you bring the clutch up, for some reason the revs increase and thus handbrake is released yet nobody touching throttle.

Yeah, I was about to say I've driven 7 DSG different equipped VW and Audi models over the past 3 years and I never had a single instance of this. Auto-hold and electric hand brake were fantastic.

We're now got another DSG with Auto-Hold but it has a manual handbrake so we won't have this issue. I can definitely understand how it's happening though. Shame they don't seem to be willing to fix it.

Hello again,


please, if you have a web link to those cases or you can indicate me the source would be very helpful.

I have been thinking several times about selling the car, but I will try to get to the bottom of this matter

Here you can see several testimonials and I have included photos of data captured with OBDELEVEN while the car was failing.
There are maximum and minimum values ​​in the travel of the gear lever (1300 and 3300). When the failure happens these values ​​appear at zero and there is another value that indicates the status of the shift lever, and this other value indicates "gear engaged" when the car at that moment is in neutral :

The neutral gear sensor has been replaced, but the problem continues

Ok. That doesn’t t sound right then.

Does it make any difference if you park in first gear then shift to neutral when the car starts?

I always park in gear then shift to neutral and never had it release on me

Has anyone had any luck with VW over the EPB ’failure’?

I’ve recently experienced this problem. I have a very gently sloping drive and after being parked for nearly two hours my 2017 Golf SE Nav rolled off it and in to a car parked in the road.

As discussed in the forum the EPB is automatically applied when the engine is switched off so I can’t see how this can be attributed to human error by accidentally forgetting to apply it.

The car is with VW for examination but as expected, so far they can’t find a fault!

It isn't though is it? You need to "switch it on" with the foot brake. 99.99% of the time you do this anyway.

As also said, you should leave your car in gear as a back up.
