Additional High Beam Lights 2005 Cayenne Turbo


Go to solution Solved by omolddesign,

Recommended Posts

I have not been able to get my additional high beams to come on. I have checked bulbs replaced a failing headlamp harness, replaced the broken mounting bracket and tested contacts. I examined the headlight unit and discovered the additional lamps are not controlled by the ballast. I tested the corresponding terminals but got no voltage terminals 5 and 7. The main lamps do lift up for high beam and the corner lamps go out but the addition halogen H7 lamps do not come on.

I also pulled the 40amp fuse from the left fuse panel as I read this would reset the lights.

Am I missing a relay that turns them on external to the headlight unit? I have no wiring diagram so I am at a loss. Is this something that is programmable through the OBD2?

Any help would be appreciated many thanks.

 

I have run diagnostics and have the following error:

 

02088 - Lights for Auxiliary High Beams
            007 - Short to Ground - Intermittent

I assume by "additional high beams" you mean the halogen flash-to-pass beams?  With bi-xenon lights they aren't supposed to come on. They are used for flashing when the HID's aren't on, and DLR's - and not much else.

Interesting idea but not true according to the diagnostics, giving a high beam error. The HID's are meant to fill the gap when the bi-xenon's point up. Thanks anyway
