New Fault code Revealed

[oggydoodaa]

So today I was on my way home from work and I had the pleasure of receiving a new warning light on my dashboard (along with the already MOT Failing ones) which happened to be an Engine Warning Light, once home I dug out my laptop and plugged into VCDS and it told me that I was the lucky winner of a "P1137 Fuel trim: bank 1 System too rich" fault code. Can anyone shed some light for me? which cylinders are "bank 1" and what it could mean if its running too rich? I would like any suggestions of where to start as my MOT is 22nd February (cutting it close!) and I need my car daily. I am a trained mechanic although not in the industry so no need to simplify for me.



Any help will be Greatly Apprieciated!!

Bank one usually means pre cat oxygen sensor.

Bank two is post cat.
