Hi, just thought I'd ask, my audi goes into limp mode using, code: "system too rich on bank 1" without it's fine. Their maybe more than one combined reasons for the problem, ie leaky injectors?

One problem suggested was that I was adding wm too early causing the iat sensor (1psi, silly i know) to overcool causing a rich mixture (confusing the computer to run choke) to trigger the fault code. However now its 5psi starting point and still occurs.

I find I can avoid limp mode by keeping the revs up, stayin on throttle.

Any suggestions?

 

Pretty sure you are on the wrong forum.

 

You don't need methanol, only water.
That'll fix it.
