    Mornin' all,

    I wonder if some helpful people could suggest some things here. I had the EML come on this week (prior to Revo upgrade), codes read were:

    P1138 Long Term Fuel Trim Add,Fuel,Bank2 System too Lean
    P1136 Long Term Fuel Trim Add,Fuel,Bank1 System too Lean

    Had the Revo flash and reset the codes, but the light came back on the next morning. Took it to Audi and they read the same codes, reset them again and told me to come back if it happened again. I'm pretty sure it will, just waiting for the light.

    What are the possible/probably causes of this error? They seemed to think they'd swap the lambda out if it happens again but from what I've read the MAF seems a more likely cause. Pretty [censored] at them to be honest, I could of cleared the codes myself - I wanted them to investigate and fix it!!

    Cheers,
    Adam

    Dealer changed the MAF and the car feels 1000000 times better, no light on yet either.
