Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.

Audi TT Quattro Problems
Check Engine Light Due to Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault
Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.
Sway Bar Replacement to Correct Creaking Noise
A creaking type noise may be noted from the front suspension. Replacement of the front sway bar may be required to correct this issue.

Automatic Transmission Shifts Into Neutral Without Warning
RepairPal Expert Overview:

my battery was dead so i jumped the car and now it will not go over 10 miles per hour and when I press on the gas nothing happens
How many miles would you expect to get before replacing a turbo. What would be a sign of impending failure? Looking at a quatro with 153k miles, well maintained.
When I run the car cold (as it needs to be), and I shift into 2nd, it get an audible grind (but the gear catches fine). As the car warms up, the sound disappears completely on 2nd gear shift. Occas...
I fear my 2nd and 3rd gear syncro's are on their way out, I'm going to do a transmission fluid replacement ASAP to see if my gear grinding shift problems are solved. However, just in case...
Audi TT Quattro Reviews
Love my tt,but can anyone tell me what is wrong with it? It has a banging sound which only makes a noise in 1st gear on acceloration.It sounds like it is coming from the front driver's side wheel.It is not the gearbox,could this be a strut top mount or a bush of somekind.It has been to the garage and they are having difficulties in finding the problem.I have been told that everything is fine,obviously not as i can feel the knock through the footwell.

2003 TT Quatro 6 speed manual: Headlight low beams occasionally don't work. Replaced both balast & both bulbs ($300 parts); lights still don't work regularly. Dash indicator shows headlight out when they're both working. Can't seem to fix this headlight problem - got pulled over several times for no headlight(s). Often try to start engine & alarm goes off. At 115k miles the shifter fork broke inside manual transmission leaving the car stuck in first gear; $2,500 repair at local shop.
I am generally happy with the car, but I have had a rear control arm break 4 times in the last 2 years. This part was recalled in 2002, but apparently was not replaced with a sufficient part. Every mechanic has commented on how light-duty the part seems. Audi International and the local dealer have been difficult to deal with.
The car is great but has given me plenty of problems:
Once I had to replace the entire dashboard instruments set because they stopped working, very expensive!
I also have problems with the sway bar, making noises.
Finally, the MAF sensor is now causing intermitent failure of the turbo; I will replace it next week hoping that helps.
Finally, I have had watter heating problems when running at high revs in the highway.
Love the car!! Got it used and get awsome comments from my classmates. Very reliable
