Because ECUs are expensive new ($900–$1500 from VW/Audi), many buyers turn to used or rebuilt units. Here is expert advice:

If you are seeing alongside 637.07 , do not continue cranking the engine. This combination indicates that the internal high-pressure fuel pump or engine timing assembly is out of alignment, and continuous operation could cause catastrophic internal engine failure. ecu 63610

The position sensor relies on a magnetic tip to read a reluctor wheel inside the engine. Metal shavings, grit, or oil sludge buildup on the tip of the sensor will block or distort the magnetic field, causing irregular signals. 3. Wiring Harness Degradation Because ECUs are expensive new ($900–$1500 from VW/Audi),

Many mechanics recommend replacing the standard wiring with a twisted-pair harness . A twisted-pair design helps shield the signal from electromagnetic noise, which is vital in modern electronic diesel engines. Step 3: Check for Electromagnetic Interference (EMI) The position sensor relies on a magnetic tip
