Description

Adblue and NOx reduction systems Diagnostics are one of the most tricky systems to diagnose right first time, due to the complex nature of the systems function and operation.

Misdiagnosis can lead to technician stress, with jobs coming back multiple times for the same fault. This can also cause the workshop to lose money on wasted time and unnecessary parts being fitted.

In addition to this, customer complaints for incorrectly diagnosed Adblue faults are high and attract negative customer feedback for your business on google reviews.

Attending this course will help you prevent all these negatives occurrences from happening to you.

This course will teach you how to diagnose beyond the code, to diagnose faults that can’t be cleared and to reset the system successfully after a repair:
