Mk7 Golf R Discussion Thread

[team_v]

The start/stop button, I think it's a bit un-necessary. Maybe it's me being a bit old-skool. My main gripe with that would be that VGA found it more important to have a start/stop button than a decent nav screen. (I know that it comes down to a final landed in AU price)
One problem I did have with it was you'd pull up in your driveway and the auto stop/start would stop the car and pressing it again to stop (as you would turn off a key)... It started again! lol
Something to learn to live with I guess...

Correct me if i am wrong but the xenon housings still have a halogen bulb for high beams don't they?
Can't you just get an uprated bulb (osram rallye etc) like i did for my halogen housings.

I think bi-xenons use xenon for both high and low beam. There is a halogen H7 for static cornering light.

But I didn't think they were bad (not that I get to use them on high beam too much)

On the Mk7, the inner halogen H7 high beam has been dropped on Bi-Xenon systems. This used to accompany all Xenon and Bi-Xenon systems, and for the latter, the H7 high beam was primarily for flashing/passing duties, as the previous HID design/globe was relatively slow to reach full intensity. However, current HID technology allows for almost instant full luminescence.

This is correct for the all Mk7's with Bi-Xenon headlights.

That's interesting.
So the inner housing on this one contains a bi-xenon bulb?
It looks like a halogen housing.

That inner lamp is nothing more than a position light of low intensity, quite pointless in function, given the brightness of the U-shape DRL's.

I don't think they implied that. You don't need anything on the inner lights I think was the implication.
On the mk6R, the inner is the indicator bulb, and it looks the same on the mk7 to me (looking at that img on my phone screen in Tapatalk).

The indicator function is provided by the led strip below the bulb housings (follows the silver grill line)
So is the high beam just a brighter output of the outer xenon bulb or is it the inner bulb?
If it is the inner bulb, i don't believe it is a bi-xenon as it would require a reflector housing to operate effectively.

[Mikey1]

So is the high beam just a brighter output of the outer xenon bulb or is it the inner bulb?

The high beam is incorporated in the outer Bi-Xenon projector lamp where the 35W HID bulb operates at maximum intensity when activated. By design, the system includes an electro-mechanical shutter which provides the cut-off on low beam, while on high beam the shutter retracts.

Ahh okay, that makes sense now.
So to remedy the original problem, we just need to install brighter output bi-xenon bulbs.

HID systems are far more rigid in design than halogen, and therefore AFAIK there is no performance variation to the bulb, other than its lumen colour temperature. Standard 4300K bulbs provide the highest brightness. The higher the colour temperature, the bluer the light will be, and the lower will be its effective brightness.
