Good post, FM.
I bought my E92 320i M-Sport, new, in April 08 and it will go back to BMW at the end of this April. Despite reading the horror stories on here I nevertheless believed I was going to see out my tenure unscathed until a few weeks ago when the EML light came on and the car began shaking like a shitting dog. I can't fault the service with BMW Emergency Service who were there within 20 minutes and replaced a coil and an injector and again it has been fine since. However, when I decide on the replacement over the next couple of weeks it will not be powered by this engine.
