My car is a 2007 E90 320d (163) with 44,000 miles on, FSH.
I've been reading various threads on here and elsewhere about EGR stats and main stats failing.
I've had some pretty shocking MPG (29 - 33mpg ) recently, so wondered if this part of my problem.
I've done the 'hidden menu' trick and generally it takes over 15 minutes for the temp to break 80C.
It does get up to 86, but can fall back to around 83 on downhill or 'easy' load sections.
My commute is 20 miles each way pretty mixed rural / urban but no motorway, average overall speed shows around 30mph on the OBC).

Should it be warming up quicker and if so is the EGR stat the likely culprit.

Thanks!
