I have a simple question I wanted to ask about the opening of the roof.

My understanding is that if theres around 500mm clear past the rear of the Eos - it will open...but what if there is sufficient space past the rear...but not above?
There arent any sensors that monitor this are there? The height I mean.

What possible scenario could there be for this?
The basement at my office for example - low concrete ceiling level - but no problem about the clear distance behind where it will be parked.

Yes, you could attempt to guess clearance, or physically measure it...not practical.

What sort of area or angle do the sensors measure the distance?????????????? How do they work??

Can someone give me some thoughts on this?

Davey, I would stand outside the car and have someone else raise/lower the roof and see how high it goes. I don't think it goes much higher than the the lip of the raised boot. I raise and lower in my garage with the standard 8' ceiling.

Hey Davey

The sensors only look behind the vehicle for clearance not above it. As far as the boot lid goes if you don't hit anything opening it normally then you have enough room to lower or raise the roof. You will find the boot lid on the Eos opens higher than most cars anyway

Thanks Leigh

Thanks Steve also.

Basic question I know - there was another reason, and thats this... a colleague of mine, his wife has the Astra Twin-Top hard top convertible. He flat out refuses to activate the roof in our car basement at the office - I dont think theres sensors anywhere on the back of the TwinTop, so I thought I should ask the q regardless.

Thanks again

YOu just need to get to know how it works, then you will be able to look at what is happening and make a judgement as to whether there is enough room to open the roof...

Or an insurance claim

As a side issue, is there a way of disabling the roof opening ? I'm thinking of various situations (apart from being under a low ceiling) where it would be bad for exploring fingers to be able to open the roof.

 

[davidp]

I'm not volunteering to try it but i would have thought if part of the roof met an obstruction during opening it would stop rather than keep grinding on. Surely it cant be that hard to design the roof so its stops when encountering an unexpected load?

 

[SiJ2000]

I don't think it will stop if it finds load... This is because something that heavy requires so much load itself, that it would be very hard for a sensor to differentiate between normal and slightly above normal load... For example if you open the roof on a slight incline...

You MUST be sure of the clearance before opening....

The only realistic way to inhibit the roof, would be to open the parcel cover in the boot. This will stop the roof from functioning...

You could leave it open all the time and only close it when you know you will be using the roof...

That's the kind of thing I had in mind, but I'm a bit surprised VW didn't fit a switch to disable opening.

Hi Simon,
I cant see it being that difficult to monitor the load on the motors. There would be a considerable increase in motor strain if the moving roof encountered a fixed object. Don't forget such sensors are employed in the sunroof and the windows to stop hands/limbs being trapped. When the obstruction is detected via motor load the windows and sunroof retratch. Surely that must apply to the roof as well.
Mind you I'm not going to test it out to prove the theory, so we'll probably never know till someone does it by accident.

Ok,
interesting responses.

Can you tell me...when you activate the roof to fold away... and the basement roof is rather low - its unusually low because also of the overhead air con ducting too - but lets say it gets rather close to the ceiling height...it is possible to stop the roof from further opening , right? Using the switch in the vehicle?

 

[sydeos]

If you release the switch Davey everything comes to a halt. then move the switch in the other direction and the process reverses.

As far as fitting extra sensors to the roof mechanism goes I think it would just make what is a complicated mechanism more complicated and more prone to problems. Particularly if sensors get out of tolerance and could leave you with an inoperable roof which could be a real problem if there was impending precipitation.

Impending precipitation eh? You mean it's gonna pi** it down?!

We don't know the meaning of the word "rain" in Sydney neh321...

 

[SiJ2000]

DavidP, I agree with you in part, but because the actuation is hydraulic, it is much harder for the pressure to be measured. Resistance in an electric motor drive would be much easier to monitor...

Too much damage would be done before the hydraulic pressure would hit a point that it would be notable.

It doesn't have too much in common with Hull then...!

One day I'll make it there!

Not to sound too much like an Arse, but when it comes down to sensors, the best sensor is the OPERATOR...

That being said, if you can stand up in the parking area you can probably open the roof, unless you literally are shorter than the car itself. Many convertible roofs flip up when they are going into the trunk/boot, but the Eos does not. I regularly open and close my roof in my garage, but I do it with my garage door open, due to the fact that I am very close to the garage door. I have not measured the rise of the roof but I would say that it goes up less than the height of a regular SUV.

I did not purchase the PDC stuff, because I figure if I am not paying enough attention to see what I am doing then I deserve the damage that I get.

Agree with your first comment wholeheartedly however in Australia PDC is standard not an option

As for not getting any rain well which part of Sydney are you hiding in at the moment Davey

Doh!
The cats out of the bag
Generally its dry as a bone fellow forum readers...but yes, we did in fact get a dollop of rain recently
