Hi there.

I have bmw f30 320d 2012 which seems to have started consume more fuel after I got the car chipped. Range has always been ~1000 km, now it's ~800 km. My driving habits are the same now as before. I later turned everything back to original (removed the chip) but it's still in the ~800 km range. What could be causing this? One guy told me that there could be problems with dpf, although the car itself does not inform me of anything wrong.

Any thoughts?

I would consider plugging in car as I know for me my egr was causing issues which reduced my consumption to somewhere around 10-15%
Egr and dpf issues seem to be a culprit for many of these cars
A professional custom tune can be used to map out the egr and blank the dpf once it’s gutted
Be worth plugging it in and seeing if there’s an underlying issue first

Also I started using a fuel additive product called dipetane
Works great
