2.0 Fabia probs

[Chris S]

Hi all, I have a problem with my fabia 2.0. I am getting, according to the trip display 24mpg which im thinking is pretty poor. Having had a new lambda sensor fitted due to the engine light coming on the fuel consumption has suffered (i used to do 32mpg) .I have had the battery disconnected to re set the ecu and have cleaned the throttle body. Im wondering if there is some kind of re calibration for the idle/throttle as the idle is a little lumpy.

I now get 240 miles to the tank where as i used to get 320 miles.

Any suggestions much appreciated

i get about 40 miles per gallon out of mine.... there is a procedure for resetting the thottle body using vag-com.... but there isn't any way of doing it manually i'm afraid

Try cleaning the MAF, if it is reading too much air coming in it will fuel accordingly. May have been the cause of the the probe throwing up a fault, there could have been an excess of fuel causing it to show a false fault.

What condition is the air filter in?

[Chris S]

The air filter nice and clean, when you say clean the air flow sensor do you mean just blow it out with an air line?

I take vag-com is the skoda diagnostic machine

clean the maf with a solvent like carb or brake cleaner...

vag-com is a pc based version of the diagnostics equipment that skoda use which is available to the masses
