Yeah could be the reason why. Maybe if we cover the ballast in something - rubber - it might stop the interference.
That's an interesting point. My ballasts aren't secured to the car, they just dangle, maybe not causing the interference that others are experiencing?
I had this problem with hids on my mk1. It is caused by interference in the 12v supply to the ballasts. I cured mine with a pair of ferrite cores which absorb the interference.
I'll take pictures of where my ballasts are positioned tomorrow. They're almost exactly where olitaylor's ballasts are, though.
What ballasts do you have?? There really bright!

Like these?
(I'm guessing it's 5mm from memory but shall check in the morning)
But that's what I need?
