320D poor consumption - help pls.
Hi guys...my E90 320D used to do 40 MPG combined and recently the MPG got dropped to 28MPG. Upon checking the threads on this forum I have had both the EGR and Main stats changed now and also the coolent! I can see the temp going up to 89C to 91C, unfortunately my fuel consumption is still bad, I am only getting 32 MPG combined. Any ideas what else could be wrong?

You can get ones for £15-£20 and they will do everything you need to do! Then once you have it you can use it at your leisure. Its pretty simple |

When driving around town I can only go ~350 miles on full tank. And again - 0 errors shows in OBD. |

I think 42-50mpg on a run is okay for one of these, I average 45mpg on motorway type runs, 35 round town.

If the car doesn't notice a fault it could be things such as poor maintenance, coked up EGR valve, faulty thermostat. Its always nice to scan a car first of all and then take it from there. Gives you a good idea straight away rather than 2nd guessing |

Autel Maxi Scan MS309 is the one i've just bought.
(Actually bought it for my van but hoping it works on the bmw too) £15 or so on ebay. Hasn't arrived yet but if you give me a few days i'll let you know if it works etc. I had a cheap one for my VW cars that worked a treat so hopefully this is the same scenario |
