Guest SJE32 Posted March 8, 2011 Posted March 8, 2011 Hello to All. After a drive back this morning in the dark I noticed that both headlights started to flicker, this is not the normal one where the suspension pump kicks in, its like just before a bulb going to blow, they flicker indiscriminately with each other. the battery is quite new and I have checked all fuses and terminal for good earth seating. Has any one had this and found out why? RegardsSJE32 Quote
Guest Jeraldo Posted March 8, 2011 Posted March 8, 2011 Hi SJE32! I have a C5 estate on a 53 plate and it's done it all its life since new. Have had it checked out by main dealerships, independents and can't find anything wrong with it, so I just live with it. The other odd thing is the illuminated switches on the door controls (windows, mirrors etc) which also momentarily go off and on. Again, can't find anything wrong with it.

Jeraldo Hi Its 100% not the pump effect, where the lights will dim very briefly for a split second, this is like I said before, a flickering like a loose connection would cause, but both lights at the same time, I thought it might me the alternator or battery, so I have had them checked this morning and both are fine, the garage even put a new alternator on to see the effect, its still there, so the old one went back on. I am still hunting. Quote
Guest SJE32 Posted March 17, 2011 Posted March 17, 2011 Its fixed. It was the Valeo alternator 80amp, after changing the battery and the problem persisted, I got hold of a 2nd hand Valeo alternator from my local scrap yard £42 inc Vat, went back a happy teddy to put it on the car only to find out the back plates are different :( I thought I would have to return to the scrap yard, the back plate of the one I got was made 06 and had connectors that were different than mine, the main cable was the same but the signal cable was now a twin pin push plug. http://i173.photobucket.com/albums/w74/dunstonuk/C5/ValeoalternatorS16-061backplate.jpg After removing the cover I found the only visible difference inside was that the sensor connector in the new cap was covered http://i173.photobucket.com/albums/w74/dunstonuk/C5/ValeoalternatorS16-061.jpg The one that had was an open connector to a single pole sensor, http://i173.photobucket.com/albums/w74/dunstonuk/C5/ValeoalternatorS12-02a.jpg so to solve all I did was change the end plates over and bingo, no more flickering lights, no more rouge messages about charging fault and abs or punctures. So again all is well with my C5 till next time Bye All Quote
