The Airtronic L6 coupled with an Easy Start Pro will give a text-based fault description, reducing confusion and saving time diagnosing any issue. In the unlikely event of a heater fault, the workshop menu can be used to find P000 codes (identified in the workshop manual) for further fault finding.

My Image Low maintenance
