oil change

Hi guys, The other day I changed the oil, oil filter and air filter on my new Z3. It REALLY needed it! I then took it for a spin. After about 45 mins into the drive, my engine management light appeared on the dash. I was wondering if you guys have had the same issue before, on one similar to...

Watched a guy do a service on his zeeee 4M ( yes, he's American! ) but, he was using a topside oil extractor. I know they use a similar method in most garages, was just wondering if anyone had used and had any success to something similar at home?
