My memory has failed me- can anyone remind me if the litronic headlights should come on in ignition position 1 ie warning lights check on etc (but engine not started)?
Leading evidence: 'Check on etc (but engine not started)' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check on etc (but engine not started)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Not sure if you have the 55w or 35w version, but if you open the lights as oif to replace the buld you should be able to get the part number for the ballast from the back.

But after I've run the car for a bit they will come on when switched on with just the ignition on.

ignition on or engine running makes no difference to this system .

basically there is no battery management and no system that would stop them from working without the engine running so im thinking voltages ..
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Mine do not, but then will come on when the engine is running.
On a couple of occasions, they won't switch on just after the engine is started... could this be the ECU waiting for voltage to stabilise, or some other fault developing... light switch?
If you turn the ignition on then turn on the headlights they should work .. they don't just come on with the ignition on so am i missing something here ?
car running or ign on and you turn on the headlights and they don't work would indicate a light switch fault ... turn lights on and off several times to see if they suddenly come on which would lean towards a light switch fault .
Not sure if i understand your fault correctly atm .. so as i say at work .. more info req please
Thanks for posting Demort...
What I mean is, if I don't start the car, but turn the ignition on, and the lights on, the litronics don't fire up... I can't remember whether they would normally work without the engine running.
A couple of times recently, after starting, when I turn the switch the Litronics don't come on until a few moments have passed and I turn the switch off and on again.
Clear as mud...?
That doesn't sound correct to me .. ignition on or engine running makes no difference to this system .
basically there is no battery management and no system that would stop them from working without the engine running so im thinking voltages .. that's the only difference .. 12 ign on - 13.5 / 14 volts engine running .. an electrical contact somewhere .
A few seconds till they fire up is normal though .. high voltage system and i guess it builds a charge :dont know:
For now .. they work with the car running .. im guessing at a light switch but i think you should just carry on as normal and see how it goes .. nothing is broken as such atm so if it ain't broke ..
Still something going on. Lights will only work initially with the engine running. But after I've run the car for a bit they will come on when switched on with just the ignition on.
Voltage looks ok on the gauge.
Could it be the battery in the way out? The car is left on a trickle/conditioner. :?:
I think it might be your light switch giving out - not uncommon. When mine started failing, it would put the headlights out every time you tried to put it on full beam. That got my attention on a dark night I don't mind telling you...
I had a similar problem when the aftermarket HIDS4U ballast stopped working. Not sure if you have the 55w or 35w version, but if you open the lights as oif to replace the buld you should be able to get the part number for the ballast from the back.
A genuine OEM version is on the bay here

but lower-priced ones are available with a bit of searching..!
blimey!
I've ordered a new switch, hopefully that's it.
Seems odd though that it works ok when it's been run.
I did wonder about a ballast... we'll see.
