Do you also have a speedo that is not working, ABS lights on? If so, you may be having ABS module issues. This is from a site that rebuilds electronic control modules: http://bit.ly/8z7rcm Common Problems: • ABS Pump running continuously. • ABS or TRACS warning lamp on. • Speedometer "twitchy" or erratic at times. • Cruise control randomly surges. They also state other problems with the instrument panel: "This rebuild is guaranteed to restore your improperly functioning instrument cluster for Audi TT with intermittent or total loss of all gauges, temp and fuel gauges which read incorrectly, dead clock, odometer and/or failure of LED backlighting"

some tt eng/trans combo have had a problem with the dual mass flywheel causing vibrations and in some it is related to the haldex final drive. i dont know if you want to, but if you post your vin# i could check for bulletins. the p0501 code can be set from extensive cranking on occasion but if the sensor is bad the car will not start. if the fault sets regularly, i would suggest replacing the sensor.
