Service bulletin LI07.70-P-078547

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

Complaint Engine idle fluctuates or stumbles at approximately 7 second interval. No relevant fault codes are stored. If fault codes are stored or check engine light illuminated, this should be diagnosed separately. Cause Torque signal mismatch between MRG and PTCU control units. Only effects version 20B of PTCU. Remedy Software solution in development and LI will be updated once an ETA is available. Replacing parts will not resolve this symptom. Vehicle can be released to owner if there are no other symptoms present. The idle fluctuation typically resolves after several trips and will not cause other drivability symptoms or damage to the vehicle. Create an informational TIPS case and submit to the powertrain team with the below information: -Video showing the "engine data" from head unit while symptom active -N3/10 MRG2 control unit log
