Seems very low for a car that doesn't weight that much for the size of the engine?

Cold mornings? Is it heating up right? What plugs did you put into it?
Yep its heating up right, starting from cold to and from work, takes me about a half an hour each way. The needle gets up to half way after about five minutes or so.

I put a set of Bosch sparkplugs in her, but this is the first tank I've paid attention to my mileage since I got her.

The only thing I can read is maybe a dodgy camshaft sensor? Might be over fueling? Prob best to wait to see if any codes are showing before I start replacing things?

Thanks lads
The 330i I had used to get 30-31mpg at 80mph on the motorway! around 25 tipping about town so getting a little over 20mpg seems rather low.
