MFA, is this right?

[dan_apps]

just noticed MFA seems to be working fine apart from the mpg reading, average about 30mpg on motorways etc usually but since i changed the clutch cable whatever im doing i.e. pootling in traffic or flat out down the M4 it says im not doing more than 14mpg?!? am i just expecting too much from 18 yr old technology or have i broken something?  :embarassed:

cheers Dan

i also have this issue, was working fine (well i was excepting the read out at around 28 mpg on average) but has since stopped working for no reason it seems and now reads about 12mpg at an absolute best!!!  i believe it works using a vacuum tube to the back of the clocks? could this be a perished pipe/leaking?

any help would also be appreciated!

yes

Mines the same, its off by a factor of 3 - only ever shows 13mpg. My pipes alright - I would have thought if it were leaking the sensor would show less vacuum > more miles, which should be higher mpg.

I've been lead to think its just the sensor on the back of the clocks itself.

Mine used to read about 9-12, got the vacuum pipe fixed and its now reads 35ish

ok so looks like ive fooked it then, i belive there is a clear pipe that runs throught the hole from the engine bay to the cabin, must have been where i rammed the new clutch cable through! ah well

thanks guys

I have the exact same problem too!!

guess I will look into getting that sorted then!!!

check for a clear vacuum tube near the ignition coil on the bulkhead, it slips inside a braided hose. mine came out of the braided hose and was reading 12mpg 

i stuck it back in and straight back up to 35/40 mpg
