Superb III Sportline - Mission Impossible Spec

[PlatinumCupraR]

Erm WOW! That's it, that's all I have, I'm drained just reading through it all. That there is an artist at work.

All I'm hoping for is a rear view camera, data usb in the armrest and perhaps a heated steering wheel!

So little bit of a side line now... and something I am 99.9% hasnt been done before...

 

Ventilated Sportline Seats

 

 

So this was an all new project and going in blind! So a bit of theory behind it first:

On the superb, all seat frames are near enough the same, then the difference between the leather and sportline seats is the foam insides and the headrest. 

There are no ventilated parts for the sportline and the ones built into the leather seat foam are far from the right shape, so it meant starting from scratch.

Also something to note - the fans suck air through the seat, not blow air onto you.

 

The parts that were needed for this:

4x Fans

Wiring

Plugs

Terminals

Diffuser sheet

Isolator sheet

Fan mounting

 

Now the fans, wiring and terminals are easy to source but the sheets and mountings are actually built into the seat foam and cant be purchased separately.

I then found a company that sold me all 4 diffuser and isolator sheets and some mountings that would work. Now we are in business!

 

There are 2 fans per seat, and they are wired exactly the same (almost) and controlled by LIN.

Each seat gets a power on pin 1, a LIN on pin 3 and a ground on pin 2. Pins 4-6 are then grounded differently depending on the fans position and this is how the LIN knows what each seat fan is doing and where it is.

 

 

Thats the wiring out of the way, next the physical mounting of everything:

So this is a cross section of how it currently looks:

 

Yellow is the solid seat foam

Red is the heated seat element

Black is the seat fabric itself.

 

 

 

And this is how it ended up looking:

 

Yellow is the seat foam which now has holes going through it completely, indicated by the brown lines

Red is the heated seat element which is porous so needed no modification

Black is the seat fabric, again it was porous and luckily no modification needed.

Blue is the diffuser sheet - which is a semi rigid sheet that is full of holes allowing the air to distribute fully across all the holes, even with a persons weight pushing on them.

Green is the isolator sheet - this is what seals the area to allow the only air being sucked it to be from the front of the seat, via the holes in the foam.

Brown circle is the fan.

 

 

And now some photos of it all - the parts and strip down first:

A rough marking of the fan location and the foam being cut

The seat base to show the 2 circle holes where the fan could possibly mount

The fan, mounting, diffuser sheet and isolator sheet

Decided on mounting the fan is the forward seat base hole

 

A torch behind the fabric to show the holes are require permiable, so air wont have an issue.

 

 

 

 

Next is the actual building of it all:

Seat back wired up and fully ready to refit, fan installed

Seat base foam cut, very roughly before sanding it flat to give a better finish

Diffuser mat laid in the cut out

All the holes, and the foam pieces ready to fit back on top at the end to maintain its shape

Diffuser mat glued in place and trimmed to fit perfectly.

A sportline seat base - the head rest is what gives it its shape, very odd design

Back of the sportline foam before i began cutting

The cut out for the diffuser foam.

The holes - drilling these is pointless - i heated up a piece of rebar and melted the holes through - a drill just pushes the foam out the way.

Diffuser, isolator and fan mount fitted.

 

 

 

And some photos of the controls now fully working!

 

 

 

And all of that, took 2 whole days for a single seat! Next is the drivers seat!

It did get me thinking though.... the 4B module often refered to as the headlight control module, is actually a multi function control module and it has a lot of other odd options too - almost like extra pins for the BCM. But anyway, it has functions on there for rear seat ventilation too... just a thought. But that would mean a completely custom rear temperature control panel, intercept and inject LIN and canbus signals through my own controller... but yeah, just a thought.

Followed this from your first post. Most of it I don't understand, at all.

 

But absolute hats off to you. This is not your standard build thread!

Definitely not the usual build, done and dusted with the days of performance cars  

 

My 2000 VW Polo with a 1.8T engine fitted as well as caged and a whole bunch of other mods - running 350bhp, was a great car whilst it lasted!

Lovely engine bay!

 

Cant help but think why VW didnt offer the 1.8t as standard on the 6n Polo Gti. The 1.6 was fun, but the 1.8t on that chassis would've been a game changer.

Was umming and ahhing about the practicalities of the ventilated seats, but I'm now putting that onto the to-do list!

 

Well, apart from needing to perforate the leather I guess...

Yeah the issue with the leather seats is there is no holes whereas the ventilated leather is full of holes.

 

In your case you might be better off finding some pre ventilated seats as I don’t know about you but a single hole out of place on the perforations would drive me crazy
