Strange one today. Just finished fitting my FMIC, put everything back together - including the battery which is almost dead which was sonly disconnected for about 30min. Anyway, went to start the car for a test drive and it only just started. Then went dead with the immo light on the dash. The clocks didn’t light up either. Kept on trying but am I right in thinking that for some reason car immo is stopping the car from starting. Put the battery on charge for a few hours and hopefully it works when I try again. Going to plug into vcds also but only got lite so not sure what I can do with regard to coding car to key. This happened to anyone before?
