It should be poss to fit the roof in any car and have it do the same
Common misconception this, that the solar roof has anything at all to do with charging the battery - It doesnt.

The solar roof does indeedy have 2 simple connections that run into the passenger footwell, but it actually goes to a relay which is controlled by the climate module. The relay connects the blower fans to either the +12 from the battery, or the solar roof.

Weve done a few retrofits of the solar roof in the past, not too hard if tyou understand how it hangs together.

If the solar roof isnt connected to the blower, it aint connected to anything, and at no time is it ever connected to anything that could charge the battery...

Sorry, its annoyed me for years with people claiming the dam the solar roof charges the battery - Its an Audi for chuffs sake, the battery works perfectly well without a trickle charge...

Ian, would it be feasible to re-locate a smaller battery to the front and save some weight from those massive copper cables going to the back? Are all the looms connected near the front of the car?
No technical reason i guess, but space is a premium to say the least up front.

Interestingly, the C5 RS6 had the Battery relocated to the rear spare wheel well to 'balance weight' which sounds like crap to me, I think they just ran out of space under the hood.

In the grand scheme of things the battery weighs not that much. Throw away the passenger seat, or drive around with half a tank of petrol, both of those will save more weight

P.S. Dont underestimate the weight of the twin pane glass, its proper heavy compared to that single pane stuff....

Thanks, its good to know its possible. If only these lithium batteries where cheaper, they save 16kg over the standard battery.

Great thanks for shedding some light on that, i only thought it did charge the battery because thats what others have told me...


On a different note, here is the loom fully exposed.
I have now removed it from the car.



I haven't weighed it yet but it fills two banana boxes and I'm thinking must weigh in at around 25kg...
