Service bulletin 122-L3H8T-06

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

Concerns: All-wheel drive control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Transfer gears with a control unit containing a data record that does not comply with current standards were delivered to the dealer organisation. An improved data record is available for the vehicles on which the transfer gear or PDK transmission, which contains the transfer gear unit, was replaced during the affected period. This data record optimises the responsiveness of the all-wheel drive system.
