I have a 2008 a4. Engine light on and off. Orignal codes running lean -
mechanic could not find problem - 2x - tac jumping
finally brought to audi and they replaced gasket seal and did general maint on car. Brought car home and it was running well - today 5 days later - it's really sluggish and tac jumping a little - engine power seems low
neighbor says its cataltyic converter?????????
HELP!!!
It's a new car - warranty off because of mileage and I still have loan payments!!!! Any ideas?????
