anyway the bottom line is that since i fitted it ive been using a hell of a lot petrol..the car is stranded apart from a forge splitter diverter valve also air filter a bit mucky lol..... for example if the computer says 100 mile in tank 10 mins of normal driving then it might av gone down to lets say 80 mile even tho av not covered that millage also the needle will drop too.........been told that a wrong maf censor can cause this..is this true or is it something else.....PLEASE HELP :sos::sos::sos::sos: the car is a A4 1.8T AUTO avant 2000 plate...
 
Sounds like a case of buying cheap, buying twice. Get your wallet out and get the right one for your vehicle and give yourself a slap for trying to be tight.

A dirty MAF can have a dramatic effect on fuel use. Since cleaning mine I'm getting an extra 50 to 70 miles out of my tank.
