HID not working on dip
You are up aginst BMW's load monitoring system. The main beam is capable of passing circa 85w without the system tripping, but the dip beam trips if load exceeds 55w. Your HID lights probably draw 33w when warm, but over 100w for the first 1.5 secs. This is enough to trip the monitoring system. Unless someone knows otherwise, it is not possible to recalibrate.
The only way round is to get the dip beam circuit to operate a relay, & switch the HID light direct off the battery via a relay & fuse.
Unfortunately, when you do this, the system then sees insufficent load, & the faulty lamp sensor comes on.
So you have to fit a fault cancelling capacator as well.
Because of the way things are wired, you cannot now fit the fault cancelling capacitor into the plug & socket of the HID light, you have to wire it partly via the dip supply to the relay and partly through the 0v to the HID unit.
Sounds Horrible. doesn't it. It is. However, If you contact me at
[email protected] I will email you a PDF drawing & all details of how to do it. See my other posts re Len Wassel Autoswitch fitment to get a flavour of what is needed & how to get round problems you are encountering.
Let me know how you get on.
