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

Supersedes Technical Service Bulletin Group 74 number 14\-17 dated February 21, 2014. Customer may complain that the seat pneumatics \(side bolsters and lumbar support\) actuate without any input from the customer. This condition can occur when the vehicle is driven at high altitudes or when the outside temperature fluctuates. DTCs may be present in the front seat pneumatics control modules, J873 and J872 \(address words 88 and 89\) or in the rear seat pneumatics control modules \(in certain A8 models only\), J875 and J874 \(address words 8A and 8D\). No leak is present. There is a software issue in the seat pneumatics control modules that causes the seat pneumatics to automatically actuate in high altitudes \(change in air pressure\) or in fluctuating temperatures in order to maintain pressure.
