Limp mode, weird codes...
Driving the car home today on the freeway. Stopped in traffic nothing abnormal when I look down and I've got a check engine light. I'm stage 3 homebrew and occaisionally I'll throw a code for intermitent misfires so I think no biggie. Gauges don't show anything abnormal, car is running fine, no hiccups, temps all good. Give it a blip and find the car is in limp mode. I pull these codes:
17537 - Fuel Trim: Bank 2 (Mult): System too Rich
P1129 - 35-10 - - - Intermittent
17535 - Fuel Trim: Bank 1 (Mult): System too Rich
P1127 - 35-10 - - - Intermittent
17658 - Fuel Level too Low
P1250 - 35-00 - -
Questions:
I'm not sure why all of a sudden the car is running rich. The car is tuned via lemmiwinks and the fueling, while not optimal, has never been bad enough to throw this code. Why now? I have not touched anything or changed anything on the car in months. I thought perhaps it might be a boost leak (tear in TBB) but since the codes occured while off boost and I heard no whooshing sound when accelerating I somewhat doubt that (will do a pressure test tommorow morn).
Question two. Is the "Fuel Level Too Low" an intermitent code? I ask because last week I was on a road trip and the angry "feed me" icon came on the ceter display. The car was fueled up no more than 5 miles later and was never run dry. This code VAG pulled: does it refer to the alert I encountered last week or is it more indicative of a bad fuel level sender?
Any bright ideas why my car is in limp mode?

Followup... What is your personal TBB solution?
Pressure test shows leak in TBB, go figure. Walks like a ducks, talks like a duck...
I was running a Samco but am thinking of taking a step up and going APR bipipe but had heard a few rumblings in the past about poor casting and pin hole leaks.
What do you use, and how long have you had it? Run low boost? Hi boost?

the new rev. TBB is only $17 from the dealer, otherwise you can get a samco, either can fail and the
samco costs $70ish, see if the local dealer has a oem in stock and throw it on. thats what i did when mine tore last month, the oem should be fine for at least 20k plus chipped miles imo.
