Hi All Own a 2004 BMW 318i Sport (Saloon) Facelift.. Car has done 57k. A few days ago, whilst driving to work, the engine, abs, brake lights appeared on the dash and the radio switched off..Car was still running although when trying the windows, they were moving up/down very slowly.. I pulled into the petrol pump (had to fill up) and you guessed it, it wouldn't start (just kept clicking).. I assumed it was the battery or alternator so waited for the rac..30 mins into waiting, tried again and the car fired up..Warning lights gone, stereo working again. I had the battery changed (was the original from 2004) and alternator checked - guy said it was fine.. Today i experienced the same problem again albiet for about 5 secs (lights on dashboard although the climate control now shut off)..After 5 secs - no problem. What could it be? I know i'll need to get a diagnostic check done but wondered if anyone had any ideas before i spent money on this.. Thanks..
