Hey,
I have a 2007 Focus Mk2 ST and the xenon beam keeps going out, I pinned it down to the ballast module on the bottom of the light unit. So ive swapped that over and it sorted the issue. However, ive now had it go out three times in a few months and its always the ballast module... I dont want to buy all these modules there must be something wrong. I thought it could be water damage, but ive driven it with a new module entirely in the dry and it went out last night
Any ideas would be much appreciated!

 

Wiring issue somewhere perhaps

 

I'm on the st forums seen this problem come up as body control module wont pretend to know what it is just remember it causing this fault mate
