Service bulletin VOS1401

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Full functionality of the VAS 6356 Test Instrument Box used in conjunction with ODIS Service relies on software version compatibility. For example: If VAS 6356 software was previously installed with its supplied installation CD, the software must be removed prior to performing the initial installation of ODIS Service.
