I have a 1999 audi a6 and it was shifting kind of hard, so one day I bought some MAF cleaner and cleaned the MAF. Shortly after that the car went into limp mode. My triptronic shifting dosnt work at all and when I shift into park or out of park into any gear, it jerks real hard. Somedays it shifts better then others but I havnt drivein it a whole lot. When I first get into the car and drive it, it takes a long time to shift out of 1st gear and seems to be shifting way late in other gears, once I get foing it seems to cycle through the upper gears just fine. Its not throwing any codes besides all of the gears are lite up like a Christmas tree. The car has 151k miles on it. I torn up the carpet and checked the tcu, you could barely see some condensation on the top of the case and the inside was clean as a whistle. Im not sure what else to check. I need some help and any info would be greatly appreciated.
