530d big Consumption Problem
 

Hello im new to this site , Have 530d e61 (218PS) automatic gearbox , with big consumption problem car driven Generally in town drive consumption is around 17Liters - per 100 kilometers OR as YOU like to say is giving me around 17MPG....
I tried DPF Delete EGR Delete with egr coller bypass Stage 1 250PS , New Thermostats .....Nothing happens ..... Before I have e65 730d with same engine And consumption was much lower ...... Does anyone have some idea? Car Running excelent no smoke even on full throtle, stady idling ...... THANKS:)

Throwing parts at a problem usually does not end well. You need to have diagnostics performed or learn how to DIY.

im not diy , been going to like 20 diffrent mechanic shops , nobody knows what it is ..... first say DPF then EGR i did it all and nothing happens.... car has on dyagnostic oil level sensor failure, (Air con) AUC SENSOR , FOGGING SENSOR, only those 3 errors apear

That sounds odd. Were any of them BMW Specialists? I would not assume just because they say so or work at the dealership that they are specialists. They seem like they are guessing. A true specialist does not guess. Did any of them tell you what exactly did they check? Vacuum leaks? Pressure? Lots of things can cause poor MPG.
