M47 or N47

Giggss · 11-15-2017, 01:43 PM

I'm looking to own a 320D and I do know about the timing chain problem on the N47, however when I am browsing threads here quite a few people own an LCI 320D and don't seem to be bothered about it. I know the M47 is supposed to be bullet proof as long as I change the engine breather and remove the swirl flaps but the LCI just looks so much better. So what are peoples thoughts on this?

Go for the newest engine.

Isn't the N47 notorious for a nasty timing chain though, and I'm looking to spend about 7k max.

That is approaching 325/330 territory, that's what I'd spend my money on.

i would have to get a diesel then as 330i mpg isnt suitable for my long commute

why does the e92 show different mpg i thought it shares engines with the e90

Around 35-40mpg mixed but mainly around town.
Around 40-45+mpg on longer runs

It's worth noting that I don't really hang about so I could probably improve a bit however, I've had it mapped so its rather fun!

Also, I have the N57 lump in mine which is better on fuel (and a bit more powerful) than the previous M57.

Im getting over 45mpg mixed on my 330d. On a run at 75/80, its getting mid 50's. Easy 600 miles to a tank.

330D LCI. Thats a mixture of driving, 25% motorway, 25% town, 50% A/B roads.

Jeff123 · 11-17-2017, 03:34 AM

On my previous 325d with the N57 I used to average around 43/44. Runs would move up to higher 40's and town work high 30's. I used to drive as hard as conditions and speed cameras allowed, but never until it was warmed up.

The main issue is that these engines take around 15 minutes to reach operating temperature and that can take 25 if you drive straight into town traffic. After that, they are loose and economical.

On my 330d, still with the N57, its slightly less, but it has Xdrive.

If you really want to drive steadily, then low 50's on a run is possible. But you might as well be in a 318 if thats how you choose to drive.
