As above really?

 

I have had ch lights enabled via VCDS but now i have fitted my HID's they don't really like being used as come home lights and i don't want to cycle them more than necessary. Un fortunately having a Greenline means i haven't got fogs either to i can use those. With further VCDS coding can main beams be used instead? 

No.

Just think you have the car parked on the side of the road, imagine against trafic, and you go out and flick high beams against head on traffic.

In another words all because of safety reasons.

Why don't u turn off your CH/LH - problem solved.

Can someone explain why it is bad to use hid for ch/lh ?

I don't doubt it but I am just a bit confused.

Because HIDs A)take a little while to warm up, so may not be too effective anyway and they Don't like being turned on and off.

It's the same as with streetlights, flood lights etc, if they turn off, usually they don't switch back on again for 20mins or so to protect the control gear.

whenever a hid/xenon bulb is turned on, there is a massive power surge, required to ignite the gases.  that's why they have ballasts.

i remember reading somewhere this can go into the "thousands of volts".

 

for this very reason, i changed my CH/LH coding to use the good old halogen bulbs in my foglights.

 

also another reason why your high/main beams r still halogen bulbs.  i.e. high beam flashing.

a bi-xenon setup opens up a shutter/shield to throw a high/main beam.

Thought as much, i have turned the function off but just wanted to see if there was an option to have mains. Might look into retro fitting fog lights if its even possible. 

 

HID ballasts put out 20-50 thousand volts, not to ignite a gas but because there is no filament and the gas is excited by an electrical arc at the centre of the bulb. To jump the gap in the bulb you need a very high voltage. 

 

I have used HId's in mains before (not bi-xenon) and all told they ok. The warm up time wasnt much of an issue but you could understand why OEMs wouldnt want this effect. 

LH is governed by the "nothing happened" timer, so a max of 30 seconds.

CH will get a max of 60 seconds.

 

How far are you walking to and from the car?

We ran our Octavia with CH/LH lights set for 90seconds for almost 7 Years and 85k miles without any issues.

But they were factory fitted if that makes a difference. You should be fine so long as you're not turning them on/off/on/off which is what kills any bulb, let alone Xenon ballasts

How did you code LH?

 

I can't get the LH to stay on for more than 30 seconds (even though 60 is coded) as the "nothing's happened" timer kicks in, locks the doors again and switches off the lights. This was irrespective of HID or halogen install,

Did it via maxidot.

Did it via maxidot.

 

Ah one of those instances where "extra hardware" beats VCDS coding then.

I thought that VCDS reached the same places that MaxiDot does.

 

Does this also change the "nothing's happened" timer as well? i.e. the car doesn't re-lock after 30 secs?

No, it's either fogs or dipped beam only.

Mike - is that a VCDS job and can it be done on a pre FL 07?

IIRC those of us with a Pre-FL are stuck with dipped-beam. :(

Shame - I have it enabled but rarely use it because of the HID kit so whne I saw Mike's post hoped it could be done...

setting in maxidot......

I have this on 2010 vrs but I can't get it to work with vcds for lh and ch. I was told you needed the sensor for lights on installed from day 1 which I don't have. Anyone without lights sensor with ch lh working on fogs or normal beam?

Ok thanks, out of curiosity is it possible to fit the shutter that allows high/main throw?

I wasn't aware of this as an issue. I have factory fitted Xenons which we use as CH lights. Should I switch this off if I want to prolong the life of the bulbs? I do really like this feature will probably continue to use it if the reduction isnt too great?

unfortunately nope.

Bugger.. Thanks for the info though
