Transaction No.: 2038952/4
Release date: May 22, 2019
Notes
Repair instructions
Technical background
Customer may experience powertrain clunk feeling when driving at low load. Investigations found that improvements in the modelled auxiliary torque
drag would remove the clunk sensation
As part of the software update both the engine and transmission control modules require updating by using Software Versions
Management (SVM), both modules must be updated without interruption as detailed within the Measure section of this TPI, failure
to update the engine and transmission control modules as detailed will incur driveability issues
Remedy
The improved modelled auxiliary torque drag calibration for Mulsanne must be applied by performing this campaign process.
Customer notification
Customers do not need to be informed directly of this campaign. Please ensure that all affected vehicles are repaired during a service visit. You should
also inform your new and used car sales departments so that the vehicles affected can have this campaign applied immediately (and not just before
sale).
NOTE: Ask the customer if the engine control modules have been modified in anyway (chip tuning) Explain to the customer that updates to the
engine control modules can render the chip tuning ineffective or damage to the control modules can occur.
Ask the customer to contact the tuning contractor to establish if a software update is possible Inform the customer that if modifications have been
carried out to the engine control module Bentley
Motors or your own company will not accept liability from damage by updating the software.
Should a customer decline to have the update performed because the vehicle has been chip tuned please make your TSC aware by raising a DISS
ticket of the chip tune, the VIN and (Chip tuning) information can then be saved for future reference.
