I'm having some problems with fuel consumption on my 320i. I'm only getting 23-26mpg on a mix of driving. I used to achieve and average of around 30-33mpg.
There are no codes stored in the ecu and the generally car drives fine.
Seems to me like it could be a sensor problem? I've swapped the MAF for a spare one and its made no difference.
Any other sensors that could cause a drop in mpg?
Only other symptoms are an occasional long crank and a slight 'bunny hop' feeling when lightly reapplying the gas at around 40mph.
Thanks in advance for any help
