# Service bulletin SGI17\-27

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

DESCRIPTION OF ISSUE: A potential issue has been identified on a limited number of Land Rover vehicles within the listed Affected Vehicle Range which may have been manufactured away from process and, in some cases, have incorrectly mapped Diagnostic Trouble Codes \(DTC\) applied to the V8 5.0L S/C Petrol engine variant. Investigations have identified that the V6 3.0L S/C Petrol engine DTC mapping was incorrectly applied to the V8 5.0L S/C Petrol engine variant, which has led to incorrect cylinder identification in a misfire condition. In these instances, the engine Malfunction Indicator Lamp \(MIL\) would operate as normal but it would be difficult to diagnose the cylinder that is misfiring as all the misfire DTCs are incorrect, except for cylinders 7 and 8 which are not affected.
