chriscousins Posted January 9, 2009 Posted January 9, 2009 Hi guysMy external temp reading has started showing 20 degress plus so is clearly faulty.However, more serious is that twice in the last 2 weeks, I have remotley unlocked the car and got in, only to find when I turn the key there is nothing. No power whatsoever. Both times I have got out, waited a few mins, and tried again, and everything OK, apart from loss of radio stations.What happened today though scared me. I was driving along when the dashboard bleeped, all the warning lights lit up, then everything went dead, external lights included, and then almost immediately all blipped back to life!I'm rather worried now as I have 2 young children, and the last thing I want is total power failure driving on a busy road with them in the back seats!! I've done a few searches, and found similar occurences, but no explanation! Any advice much appreicated before I call a dealer and let my credit card get hammered!! Quote
Randombloke Posted January 9, 2009 Posted January 9, 2009 I've done a few searches, and found similar occurences, but no explanation! Any advice much appreicated before I call a dealer and let my credit card get hammered!! There are three fuse boxes in the C5. Sounds to me like you either have a faulty connection from the battery to main electrics in the car, or a dodgy fuse or similar. The first thing to do is to carefully check all the fuse boxes, I would start with the main one in the engine, it has the biggest 8 fuses in it (I'm looking at the 2.0/2.2 HDi), and is close to the main ECU, just behind the battery, as are the second set. The third set are in the glove compartment. All wires tight and secure? All fuses seated properly in their sockets? No fuses looking to have cracks or damage in the fusible section? Also, some C5s have a quick release set of battery connectors (mine has) are they ok with no corrosion? Are the cable secure Check the complete run of these cables back into the car main electrical system. Otherwise, dealer............... HTH................... Quote
