TPS code could be because of the wastegate valve...my car threw a
similar code when the PO took the car to the dealership to
troubleshoot low boost.  Morons replaced the TPS, but then never
re-checked to see if the low boost persisted(it did.)

One of the codes for engine speed sensor is normal if the car wasn't
running.  Run VAG-COM with the engine running and you should get no
codes(the speed sensor code disappears if the engine is running.)  If
you still get the code, try pulling the flywheel sensors and checking
for flakes of metal on the front of the sensor(s).
