Leak diagnostics (certain markets only)
To minimize false detection of leakage, new software has been released for the Engine control module (ECM). The software has been released
afterwards, in order of priority, started at the end of 2006.
To check the current software version, see Vehicle communication in VIDA.
The improved software version makes diagnostics more robust and durable against aging and wear of the leak diagnostic unit. It affects strategies,
behavior and to a degree also read off parameters.
