The engine control unit is responsible for controlling fuel delivery, ignition timing, and communication between key vehicle systems.

Common signs of a bad VW ECU include:
1. No-start condition
The engine may crank but not start if the ECU is not correctly managing ignition or fuel delivery.
2. Rough idle or stalling
A failing ECU can interrupt normal engine operation and cause unstable idle or sudden stalling.
3. Hesitation or poor acceleration
Incorrect ECU signals may reduce engine response and overall performance.
4. Misfires or warning lights
A faulty ECU may trigger the check engine light and lead to misfires or sensor-related trouble codes.
5. Poor drivability
VW ECU issues can affect overall engine smoothness, fuel efficiency, and system communication.
