So fitted hid kit today, canbus friendly. Lights OK with ignition on, go off after 5 secs with engine running. No errors so I think it is low voltage to ballasts so ballasts are shutting off. Could fit a relay but then would there not be bulb failure errors cos no power sensed on the original connectors?
 
When I tried this before I found that the bulbs were overheating and then cut out.
Never did find a solution so ended up returning them.
 
I don't think this the case here tho as with ignition on they were fine for many minutes. But it was always 5 seconds until they switched off with engine running.
 
doing more research, they both go off at the same time. I am now thinking that the circuit is being cut as the computer detects 35w and not 55w. A canceller/resistor might suit it, but when my MBII comes I'll check the error codes.
 
Just an update in case anyone is thinking of doing this, the resistors have solved the issue.

As for beam pattern, it is brighter but no further forward than the Philips extreme halogens I had in.
