Fuel Bank Warning Light Query

[samoward]

Hi!

I’ve a 2000 1.9 and an engine light has come on, took it in and was diagnosed as something to do with the fuel bank? Have had it knocked off twice. I’m driving down to Cornwall from the Lake District tomorrow-can I ignore the light for now and use the z3 for the trip or is it a more urgent issue?

thanks,
Sam

Hello
do you know the fault code?

If it’s a fuel trim exceeded code then look for a vacuum air leak check all rubber and plastic vacuum pipes particularly the intake bellows after the Maf for holes or splits replace any that you find. A smoke test would reveal any leaks you can’t find visually. Vacuum leaks will fool the car into thinking its running lean and the ecu will add fuel at the injectors to richen the mixture, it will continue to do this till it is adding 20% more fuel before giving up trying to correct it and set the engine management light to draw attention to the fault and set a code(s). You will notice that your mpg falls drastically with air leaks present.
