Multiple warning lights come on at the same time including transmission, engine, abs, esp, air bag and tpms, while these lights are on vehicle hesitates and looses complete power, this condition happened in the middle of the highway and almost caused an accident, had to tow the vahicle home and eventually to my local Audi dealership. I found on line technical bulletin sb-10053894-9766 which describes the exact sympthoms my vehicle is having, I strogly believe this should be a recall rather then a TSB.
