Replaced Throttle body throttle position sensors


There is another sensor mounted to the gas pedal. It has to communicate with the throttle body assembly. If the correlation is not correct between the two, the problem will persist. The throttle body assembly is usually the most common of the two, however the accelerator position sensor still gives problems.

Why does my car bog down and wont accelerate up a hill?


Usually a sign of a fuel problem, either too much or too little.
Too much could be several problems including a clogged air filter, too little could be a weak fuel pump or other issue.
A mechanic would check fuel pressure and air flow first.

Car looses power up a hill


How slight was the hill and how much weight did you have in your car? When you got power back was it because you were no longer on the hill or were you going downhill?
You may just need to drop down a gear to get the power back, if you have a heavy car even slight hills can cause it to lose power especially if your in top gear. You have a "sports transmission" option (I'm pretty sure it's on all the DSG transmissions) you just need to move it across to the +/- bit and move the stick to the - to go down a gear. Otherwise you'd have to wait until your auto decides it's lost enough revs to go down a gear. Which is why I hate autos.
Otherwise it could be bad fuel or something wrong with the turbo.
