ML God unfortunately does not have enough answers, that is human. The forum is about true Benz lovers and "wana be". How I wish we can have serious answers to most questions bcos where there is LOVE always there is heart break around the conner.
I LOVE my ML500

ML 320
ML God,
The fuel pump on my 98 ML 320 had to be replaced. The dash fuel guage and the MPG display were working fine before the new fuel pump was installed by the dealer. Now the dash fuel guage and the overhead MPG calculation display are both providing inaccurate readings. (The odometer continues to be accurate.) The Dash guage indicates there is 1/4 tank left when infact the tank is empty, and the overhead mileage is showing 5 miles above my actual MPG useage. Was the fuel pump improperly installed? I am now being told the new fuel pump requires the installation of a new computer/guages upgrade which will cost an additional $850 or so. Does new computer/guages have to be installed with a new gas guage?

Me & mechanic both were confident, the fuel gauge issue will disappear after fuel pump replacement, but it persisted..mechanic even tried re adapting the fule gauge...no luck...
We are both perplexed till date....only explanation that I have come up with is that there is an official TSB for upadating the cluster software...I think, the cluster needs to be reflashed on pre-2002 MLs...but that is again like taking a chance - it may or may not solve the problem..only dealer would be able to reflash the cluster, an independent likely doesn't have access to all TSB updates..
I doub't if the gauge hardware would have to replaced - it is most likely a software issue, not a hardware one..
