Having read all the comments elsewhere on this site, I am planning on selling my car that I have only owed for 2 months.
Main reason for this is not only the fuel gauge that is "RANDOM" again around the 1/4 mark, but after having this car for two weeks, I've ended up with the dreaded ECU light on all the time, and the car running rough and stalling.
After a trip to the garage, I was told the airflow meter had shot it. After buying one new off ebay "no good", then one second hand from a breaker "no good", I did a bit of googling and after about 2 hours found someone with same fault; if you get fault P0100 and p0110 (air flow meter & air temp sensor), before buying any parts, try running a new earth wire to the yellow wire on the plug to the air flow meter. After doing this it ran fine.
Hope this helps someone solve a problem cause it did my head in for about two weeks.
