HOW TO - LED Fog Lights

Has anyone thought about swapping the standard halogen Fog bulbs for LEDs?

I am thinking about doing this on the ordered A1 and using VCDS to program them for use as assisted turning lights. I think it will also be an improvement on the look, so they match the other lights when using the coming/leaving home feature.

I dont want to make it look chavvy though, haha.

would love to get this done along with the dial swoosh

sorry for seeming a little thick but you know the laptops that the audi/vw technicians carry around, can these carry out these mods? or is it a completely different laptop/software i need to find.

you can download the software np its the cable that needs to plug into your car a really good one is about 300 quid there is a post and a link to it some where on here

I have a link to a company that do a cable for use with VCDS for ÂŁ80. It works with the full version of VCDS like the Vag-Com cables.

Although, at present it is not compatable with the A1, but will be soon.

Yes, a VAG garage could do this, if they know the settings for the A1.. :)

You can pretty much do anything with VCDS if you know what you are doing of course, I have been exchanging conversation with Ross-Tech who make VCDS software with data that I have submitted to them along with other VCDS owners from here they tell me in the next release they hope to include better support for the A1 with the long coding helper and labels at the moment A1 is supported but you really need to know what you are doing because the labels are not up to date in the current release.

As for cables, I suggest the genuine cable I know its expensive at about ÂŁ260 but it's well worth the investment as the third-party cables may well be compatible but if something goes wrong when programming your car you potentially run the risk of warranty problems and will not get any support from Ross-Tech for VCDS software. At least with a genuine cable you are covered by Ross-Tech because it has a genuine serial number on the cable.

I will have a play at some point with the fog lamps to see what the procedure is.

So far the following items work with VCDS reprogramming;

DRL dimming when turn signals are on can be deactivated
DRL's can be turned off permanently if required
Staging (Gauge Sweep) can be activated
Video in motion can be enabled
Seatbelt Chime can be deactivated
Xenon Headlamps can be adjusted for European driving
Hidden Menus can be enabled in MMI Plus

As for VAG Assist technicians usually they use Panasonic tough books with VAG DIS systems on them which have a SIM card in them that communicates data over a VPN back to Audi/VW they can adjust quite a lot with those laptops however I don't believe it has the full diagnostics like workshops have for updates etc.

Thanks,
Mark

Mark, can the DRLs be changed so they stay at full brightness when the main headlights are on? And is it possible to activate the rear LEDs to come on with the DRLs?

Cheers,
Paul.

Enough room there for loads of A1's shame the House is now too small for us. Theres also land next to the drive where the grass is... Was going to build a double garage with studio above but not too sure. Theres more parking in the garden where my A1 is nice and safe hehe.

so are these lights road legal? :p
Yes road legal... Of course driving with them on when not in fog is illegal. They look alot better than the yellow fog bulbs when using the coming home leaving home auto lights.

Did you manage to find H11 LED fog bulbs that DID NOT throw up the dreaded 'Bulb Out' warning on the OBC??
No... There should be some resistors available but ones i used on my previous car got very very hot and were a fire hazard.

I tried looking on VCDS for the bulb out off function but couldnt find it... Will have another look.
