Hi Guys and gals.
I need some help/advice please. I have a pre-lci e61 525d and my consumption is ridiculous. I get on average 12mpg! I’ve recently changed both stats, the manifold, refurbished the turbo, used the injector cleaner, checked the injectors on ista d and they’re all fine, ran the diagnostics no errors and I have tried disconnecting the maf to run on default values and the consumption was higher.
Can anyone please suggest anything else I can try to increase the consumption to normal level?
Thanks in advance.
