My wife has a 2000 Beetle(I refer to it as "That German B*tch). Right after we got it, it threw a rod, found another AEG motor from a used car parts yard. I also have a XTOOL VAG401, Ever since we had it its been throwing a 17973,17987 & 17988 code, I tried to do the throttle actuator, tried to disconnect the battery, hook it back up and wait for 5 min, but the light always comes back on with the 3 codes. Also the cruise control never worked, but I am not going to deal with that until I get the throttle taken care of. I also have 3 Throttle bodies, 1 from the original, 1 from the second engine, and one I bought off of Amazon, each one does the same thing. Any suggestions?
