Flashing Xenon Headlamps?

[Yazbulls]

Has anyone had Xenon headlamps that intermittently flicker, flash, blink, wink, and do so independantly of each other such that sometimes we could be mistaken for a vehicle on a 999 call?

 

I admit, the last comment is a slight exageration, but they do exhibit all the symptons, and more and more frequently. For various other reasons the dealer has just replaced the 'BSI' (main brain?) and was hoping it would cure the problem, but it did not. Then, as it generally seems to happen as revs 'drop off', a voltage fluctuation was suspected, but that checked out okay, but the battery was only showing half charged (which is worrying in itself !!!!!) They charged it back up and reckoned that would do the trick, but no. In any case, as the bulbs flicker, flash, blink, and wink, independantly, I would think that rules out the battery, as anything to do with that or voltages would surely effect both headlamps the same.

 

I am now inclined to suspect that actual bulbs, or something direcetly linked to them. Has anyone had a similar problem, and how was it fixed. Our dealer is scratching their head, and getting little help from Citroen UK.....and unless we can find the cause of this I fear we will be without the car for many more weeks whilst it is investigated....thanks in anticipation
