E Numbers

[S6PNJ]

No, not food additives, the BMW E number classification thingy. I've never understood the E numbering system but I know it is used to 'describe' the BMW model rather than 530d for example. Is there a list showing what E number equals which model? Googling hasn't helped as I'm not after a specific number, just want to understand the system.

Thanks Kinky - my first google result was

BMW VIN Decoder - By Mitsuhiko Kanekatsu

But then I googled for "BMW e number decoder"

I gues it's all down to what you search for! Much obliged!!

No worries Phil

For reference, I searched for bmw e models
