Mein Auto: 645 csi auto
645 vanos selenoid removal ?

Hi Guys, My problem is drivin me NUTS. Cold Start. Car starts !st time. Runs for say 1 mile and I now have to stop for traffic. Engine is NOT warmed up. Now ticking over very IRRATICLY. Engine Light comes on and car is ticking over as though I have lost 4 cylinders?? I turn off the ignition and restart the car (Which has now re-set the ECU) and the car now runs PERFECTLY. (Although sometimes if I have to stop again shortly after first stop, I will have to turn off the ignition and restart again. FROM NOW ON THE CAR RUNS LIKE A DREAM ALL DAY EVERY DAY. ITS JUST THET INITIAL WARMING UP OF THE ENGINE FROM COLD START. NO CODES ARE SHOWING UP. I have cleaned the MAF. Changed the Thermostat, replaced TWO sensors on the front water pipes leading to rad. changed Air filter, Oil change plus Flushing Oil (Just in case it was a sticking valve) I am now thinking Vanos Selenoid?? Camshaft sensors ?? (4 I think ) or Pre Cat Sensors.??
Due to the fact that it only happends from COLD Start I am thinking a SENSOR giving the WRONG Info. to the ECU ??
ANY ONE GOT ANY IDEAS OR HAS COME ACROSS THIS BEFORE???
