Morning Sean,

In what way won't they work? I've taken a look through the manual and the only thing I see is the bulb replacement list and then says about the manual adjustment behind the lining.
Interested in this as I've just ordered replacements for the standards, however I've opted for the Bi-Xenons instead.

Hi Dan,

 

Not sure if I explained this clearly, as I am slightly confused myself, lol,

 

I have complete changed the full headlight unit for this one 98763117050 - my original headlight only took the standard H7 bulb,

 

The new unit - has the motors inside for directional movement and the ballast box,

 

Do you know if I need these new unit coded to the car in order for the directional lighting to work etc?

 

Thank you

 

Sean

This is the first I've heard of this honestly buddy, I've just sent a query to Eurospares in regards to if this would need to be coded, will let you know what they come back with should I get a response.
Were there any other wiring looms other than the original light cabling? would need to connect the motor somehow for it to make any changes.
Hope someone else can assist and help you more than I!

 

Cheers,

Dan

So just to follow this up, the response I got from the supplier when I asked if the headlamp unit would need to be coded...

No help what so ever in the question I asked and simply just wants to try sell one.. sorry bud, hope you get it sussed soon.

 

Cheers,

I asked a specialist about this yeeears ago and they said it's not possible to just fit the headlight and ballast as a retrofit.  You have to change the wiring harnesses too.

Can they be swopped over without having the washer unit drilled in retrospectively? 

All Xenon units had that headlight washer element  - impossible to get it without, so I think the two work in tandem with one another.

That said, I'd be interested in doing this if its not a faff and no need having to drill the body to fit those washer units.

As far as I am aware Xenon headlights must have the washers fitted or they will fail an MOT.

 

I think a dirty Xenon headlight can blind oncoming traffic and hence why the washers are fitted to keep the headlights clean in dirty weather.

I would be very surprised if it does not need to be coded at the very least. I fitted a cruise control stalk to mine the other day, even something as simple as that requires to be coded.

 

There could well be more to it than that though, others have mentioned a few things. also the light switch itself is different, the Bi-Xenon light switch has no front fog light on it.

 

You may be better asking on some of the US forums, they seem to modify there cars quite a bit. Just bear in mind there could be some differences between US and UK spec. I suspect there may be a lot more to it than just changing the light units though, self levelling, the washer unit, light switch etc.

 

Another option would be to call a good indie place, Parrs were very helpful before I bought mine, maybe give them or a close by indie a call.

Anyway, good luck with it, if it doesn't work out I guess you can resell the lights.
