Do you live in Europe? Here in north america they never sold a 2.0L TDI in a 2004 audi a4. Either way, the fault is for the power supply relay for the ECM J271 or J363 (whichever one is equipped in your vehicle). The possible causes are the relay itself, the harness/circuit between the power supply relay and J271 or it may be as simple as the fuse that supplies power to the relay.
