fuel consumption problem e46 323ci

[Shaaf1]

Hi guys.... I need urgent help...... i have the e46 323ci, something strange is happening.. i filled my tank friday (49.9 litres) after driving 382.2 kilometers i stuck without fuel & had to get some1 to bring me fuel... my gauge shows above quarter... could this be a sensor or something that's screwed?????? please help

Thanks

Yup I would think that the level sensor is most likely at fault here, well it is at least a good place to start looking.

50L got you 382.2km not very good thats 13l/100km when my car was stock i could easily get under 11l/100km for mixed driving... and i drive the crap out of my car...

Okay, it could be the level sensor as noted, or it could be that there is a problem with the fuel supply.

Seems that the tank has two compartments, with two pumps, although the one is a "SUCKING JET PUMP". It could be that for some reason one of the sides cannot supply fuel anymore - broken pump/clogged line.

Easiest way to find out if this is the problem is to fill up the tank again, and determine if it is actually empty, if it is then its the level sensor, if not, one of the sides of the tank is not supplying fuel.

Easy.

I agree. Fill the tank and if you ad like 50L THEN THERE SOMTHING WRONG WITH YOUR LEVEL SENSOR AND FUEL CONSUMPTION. If adding 20 to 30L fills the tank then theres a blackage

thanks.. but i did this test a few times, how could i physically check if theres fuel in my tank??? getting 382 from 50litres is like getting 7.6km per litre which is crazy..... i have a new fuel pump on so i dont know anymore:argh:

If you recently replaced the pump, I bet somebody did something wrong... This does sound to me like a problem with the sucking jet pump...

Shaaf1 is that sort of consumption normal for you?

 

[Shaaf1]

not normal at all....

 

[moranor@axis]

not normal at all....

well then id say there has to be some fuel left in the tank that is not being used...

how much liters do you throw in on say 350 km. If you throw in more than 30L you have a consumtion problem
