how can there be no codes if you are getting codes? are u reading the codes with a code reader or the in dash trick

the dash trick
DMR
well thats the fuel sender unit, could be on it's way out, do u ever find that your fuel gauge reads lower than it should, i.e it say u have a quarter of a tank when u know it should have a half full tank? or does it take upto 30 seconds from when u turn on the ignition for it to register?

I have just finished replacing my fuel pump/sender unit today, pain in the bloody arse
DMR
what car u got?

hi its a 1999 T reg 1.6 LX 16 valve.
DMR
long shot but how much fuel do u have in the tank when u do the in dash test? if the level is low then it might just be because of the try half a tank full see if it comes up with it then, might wanna try disconnecting the battery first for 15. if u have plenty of fuel when u tried it then i don't know, codes generally don't appair for no reason esp if they wont go away

some codes though cleared will stay on the dash until the car has completed a preset amount of driving ie a month without the fault reoccuring which is what sounds like is happening for example if you got a low battery code and replaced the battery it will still show on the dash till the car has been turned on and off so many times and completed so many miles

well if disconnecting the battery done nowt then no you cant it should be gone by now unless you have an intermittent fault that isnt being read
DMR
i agree with above, if it's been there 2 months then somethings not right, a normal diagnostics won't always pick up faults, you probably need to get a live feed done. i had my focus on diagnostics and it came up with nothing, but i had to take to to a specialist diagnostics and they found 2 fault codes. although my car did have major issues.

how often does your car run on under a quarter of a tank?? If not very often try running it below a quater and try going round a few sharp rght hand bends (roundabouts are good) see if the cars power drops
