Noticeable differences?

Did you get your lights aligned after you fitted them?

Hmm no, havent had time yet, that essential is it?

Yeah dude, otherwise they'll be shining too high and blinding oncoming traffic! These Projectors are designed to cast a beam towards the left of the road so you'll illuminate signs and stuff, rather than right and into oncoming traffic. Theres white adjuster screws - use a torx screw to adjust em. Theres one for horizontal and one for vertical.

If you google it you'll find the standards - or do what I did and take em to a friendly MOT place and have em do it for you for free

Ah thanks pal, will mention it today when im at the Vagtech place see if they can do anything about it.

Hi again everyone,

Took my car to a vag specialist today. He got my Xenons working like OEM (i think). When the switch is on auto mode the DRL's are on at a high brightness during the day, when the light sensor detects night time, the xenons come on and the drl's dim down to what looks like 50% brightness.

HOWEVER, when the switch is on auto mode (which i leave it on), now that the xenons are fixed, it shows a bulb out error on the rear fog light with the fog light on. I'm taking it back Thursday but he said any help he can get (and me) would be much appreciated.

Any ideas?

Thanks again everyone

Heres what im talking about. This is when the cars running and the switch is on auto mode.

Much appreciated.

So you mean when lights are switched to auto (and are actually on)! the fog light is always on?

[mike.]

Just had a spin around since it's dark... i got a few flashes from people, 3 on a 10 minute drive... i know xenons are pretty bright since i sometimes think oncoming cars have their high beams on. but do you think mine might be pointing upwards abit more than they should?

Thanks guys

Did you fit the AFS unit and the autoleveller.

If you didn't then everytime you go over a bump or accelerate it will look like you are on full beam which would explain why you are getting flashed.

The fog light bulb out problem is usually a BYTE 18 mis coding problem.

Yeah pretty much .

And no, there is no AFS unit or auto leveller, lights havent been aligned yet for the beam test so he's doing that thursday.

I remember him mentioning byte 18 and code 15 or something, but didnt work, we scoured through the forums for abit.

Good luck with the error bulb...if you can post the long code for thr CECM byte 18 should be 04 me thinks.

[JayGTD]

Morning dude. Byte 18 - 04 (GTI rest of the world) is what you want. I suspect what he did was he set the car to USA, and over there the fogs and reverse lights are swapped over.

^^^^^

That wouldn't put the fog or reversing light on all the time tho'. Until it's sorted, I'd pull the fog light bulb out to prevent annoying everyone behind you.

The DRLs should be at full brightness with the light switch in the OFF position as well as AUTO too.
