<< I was following this thread for a while because I have a similar problem. My
problem is car starts fine when it is cold(hasn't been started for a while),
but if I try to start it after running for a while it starts very hard!!!  I
am also not reaching full boost any more(1.4 on display). I just checked my
error code and it came out 2112. Has anyone dealt with this error before????

Per Scott Mockry's site (straight from the audi books):
2112 
Timing (62 degrees BTDC) reference sensor
Flywheel pin damaged/missing,
Mis-located Sensor, flywheel pin, distributor hall sensor out of adjustment

NOTE: If the ignition is turned on, but the engine is not running and you read the fault codes, you may get a false 2111 or 2112 (RPM and TDC sensors) fault code or 2234 (supply Voltage) fault code.
