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...
Plugs out and cleaned + Air filter replaced +
Mass Airflow Meter cleaned = bloody amazing results.
Seriously, a couple of hours spent on these simple jobs this afternoon has given fantastic results. The 6-pot is purring like a kitten!
