Default Potentially. What year is your car?

| 17536 | P1128 | Long Term Fuel Trim mult.,Bank1 System too Lean

too lean means too much air getting in after metering. Or the MAF is reading low.

So check for intake leaks PRE-TURBO but post-MAF, and maybe try cleaning your MAF (in some 99% alcohol) as well...

Mine threw lean codes when MAF died. It also went in and out of limp mode.

Default yeah, if it's a 2000, then I'd suspect the MAF.

Audi sent out an bulletin stating how they cover the MAF replacements up to 100k now, I think. So just take it to the dealer (don't clear the codes). Hopefully they won't try to give you excuses that it's something else...

Is your car stock?
