Found the E90 320d replacing the E82 120d

After a tiring week of chasing fuel efficiency and keeping my average speeds between 90–100 km/h, this is the estimated range I got after filling up. Absolutely insane. Reassuring to see that this is the kind of distance I can cover when driving frugally.

Anyone seen a higher range on a 20d?

The most I've seen in the 20d is 1250km. In general CBD traffic driving with very little highway driving I get 950-1000km on a tank.

It's a given , yes. 99% of my commute is open road with minimal traffic. Cpt traffic? We all know. Have you done the necessary deletes?

Not yet. I'm sticking to "if it ain't broke, don't fix it" for now 😅
100%. If you still have an active EGR, I'd recommend an intake manifold clean. Mine was filled with carbon gunk because I only did the delete around the 200k km mark.

Update time

I posted about a rotten egg smell in the battery compartment a few days ago. It turned out to be hydrogen sulfide from the battery itself due to it being overcharged by the alternator.

New alternator fitted today and everything seems back to normal. Will still monitor the battery closely hoping it didn't take damage.

On another note. Whilst the alternator was removed, the technician had a chance to properly clean my intake manifold, throttle body etc. Was surprise at the amount of carbon and sludge in said parts.

The car is on 237 000km now and I deleted the egr around the 200 000km mark. So, carbon build-up most probably occured prior to that.

Other than that. No complaints, 320d all day.

Attached are some before and after pics.
Note.

The EGR delete is something I've questioned more deeply, after doing mine. I had it done at 185000km when I bought the vehicle.
We replaced the intake manifold gasket, which houses the swirl flaps, to make absolutely sure they're good as new, and cleaned the intake manifold.

Considering the cost of the delete (labour + software) is more than parts & labour to replace the swirl flaps and clean the manifold, I've questioned whether it's worth doing the delete.

Is it not better keeping it stock and just replacing the swirl flaps and cleaning the manifold every 200000km?
