Facelift headlight install on pre-facelift z4 - working

[mac27040]

As you may or may not know i installed the facelift xenons to my 2003 z4. The only issue i had was the flash to pass.

The difference between the pre-facelift & facelift lights are:

Pre-facelight:
Orange indicator hockey sticks
inner lamp acts as high beam
Outer lamp (halogen or xenon) low beam
side light bulb - which you can replace with LED version

Facelift headlight:
Clear hockey sticks
No inner lamp
Outer lamp (halogen or xenon) low beam & high beam
Angel eye (just one working around the inner fake lamp)

The only way to resolve the pass to flash until now would be to replace the LCM, so the temporary fix i did was to wire in the high beam to the xenon shutter. This ment i had to always have my lights on to get flash to work.

Solution:

Have spoken with RichardP (intravee) he coded the intravee to now function flash to switch on xenons and open shutter thus works correctly.

Below is the link for the firmware which has the feature implemented correctly, with an option to turn the Flash To Pass option on or off. Under Extras, Control, Light Control, "Dip with FTP".

Just make it clear that this build is relatively untested, but if anyone has any problems with it to let me know.

Well done

Another breakthough for the deginger'ing folks!!

yep means you can easily upgrade your old headlights to the facelift using intravee

Outer lamp on pre-facelift Xenon cars does low and high beam. The shutter opens fully when you thrust your stalk forwards. The inner halogen operates when you pull on your stalk whilst flashing. Presumably this is to prevent your Xenons from firing up multiple times on a short duration if you flash without headlights on to protect your ballast from premature death.

[mac27040]

Yes but on facelift they used the xenon for flash, this causing a problem when upgrading.

Can you buy facelift halogen or are all facelift+ xenon?....any ideas on the price?

[mac27040]

Yes you can get facelift halogens, they don't come up much on eBay
Expect to pay £150 - £250 per headlight

Also halogens from pre to post facelift should be a straight swap.

If you want real rare headlights...

In 2005 they did have PRE facelifts with clears too !!!

How about pre facelift halogen to xenon? Straight swap? Or will I need to tinker? I don't have a nav screen in car so that puts me out of commission if I do really!

[mac27040]

halogen to xenon can be done but you need to fit headlight washers and level sensor to pass the MOT standards. Best bet is to upgrade to facelift halogens then fit HID xenon kit. this would be then plug and play.

I have both washers and levellers on my headlights, so it should just plug and play, right?

Xenon have a suspension mounted sensor for the auto levelers which xenons have.

As you have a dial in your car... without the sensor the xenons will probably always point to the floor!

[mac27040]

Not sure if the auto level relates to if additional weight is but in the boot the headlights adjust, you still have to manually adjust them to correct alignment

Nice work getting it coded in. If you're keeping xenon dipped on all the time then flash is fine, but if it fires the xenon each time it might cause issues for the ballast. Spec is on/off every 15 mins. Nothing to worry, but be aware.

Separately those talking about halogen to xenon, a correct conversion requires lights, self levellers. Reprogrammed of or new LCM and washers.
The cycling if halogens is not self levelling and fools many.

[RJS-Z4]

LCM is what exactly cj?

Right, as it stands my car has washers as standard and and the headlights do adjust when I turn the car on, you're saying this isn't enough? As the movement is just cycling on the halogens, not aligning like the xenons would?

So I still need to get some sort of levelling thingie m'bob also?
