Hi, Just joined and hoping to get some advice. I have a C3 1.4 hdi. Had it 3 months and pleased with it until I had a DAB radio fitted a couple weeks ago. This caused problems with the key fob and unlocking (was told this wouldn't have anthing to do with it but since discovered it has!) . Still started fine and drove fine. I decided to refit the original stereo because of the locling isue. And now it won't start at all! Had roadside assistance who couldn't start it and towed to a nearby different dealer. It seems C3's can have issues with 'after market' stereos as leads are not exactly the same. The new dab stereo was just plug n play, but fitting it and then removing it has annoyed the immobiliser somewhat! He advises main dealer but just wondering if anyone else has had this or has anything I could try first before towing it..again! Thanks
