Headlight goes out after warming up


Recommended Posts

I am battling an issue with my litronic headlights on my 2000 Boxster S. Both headlights light up correctly when I switch the lights on, but the right headlight goes out after about 30 seconds. When I switch the lights off and on again, it immediately goes on and after 30 seconds it goes out again.


This is what I have done so far (in reverse order):

* checked the ground point and put connector lube on

* opened the headlight connector in the frunk and put connector lube in all holes

* put connector lube on red connector to the low beam bulb

* put connector lube on both connectors behind the headlight

* replaced both bulbs

* replaced the ballast

* replaced the igniter

* replaced the headlight switch



I considered that this might be a relay issue, but but relay position F28, as shown in the diagram, is empty on my relay board no headlight relays on my car.



Guys I am out of ideas. Any suggestions?

You need to find out if it's in the light unit or the power track. You have done quite a few things so far.

I would take out the right headlight. Turn on the lights and after 30 or more seconds check the power block behind the right unit with a meter to establish if all there is power at the block on all the live connections. Check first with a separate earth. If there is power to all the connector points, next check that there is earth continuity.

This check will tell you if it is the light unit that is faulty or the power track to the light.

If this check shows that all the power lines are OK, borrow a similar light unit and make a substitution. This will tell you if it's the light unit that's faulty.

If it's the light unit wire it up on a bench and apply a 12v supply to check the unit.

Hope you find the fault.
