The most common issue with turbochargers in Audi A4s is oil starvation, which can lead to damage and reduced performance. Make sure to regularly check and change the oil to prevent this.

Another common issue is the wastegate actuator failing, causing the turbocharger to not function properly. Have it inspected and replaced if necessary.
