I have a 04 SeN est 2.5 Sport Tourer and it is eating headlight dip bulbs ! I have replaced 6 in the last 3 months ........It has been multi metered into next century and is not showing any elec spikes when firing up or normal running, it is also on its 3rd interior roof light as well....Any ideas ???? Halford as thinking of painting me my own parking bay !!. oh and i know how to fit bulbs etc......in this case the fault does not sit with the fitter.
