Customer statement / workshop findings
Warning lamp illuminated on Driver Instrument Panel (DIP)
“Drive system fault. Contact your Bentley dealer” displayed on DIP.
One or more of the following Diagnostic Trouble Codes (DTC’s) stored within Engine Control Modules (ECM’s) 1 or 2 (Depending on model type)

Technical background
The root cause of Exhaust Flap Control Unit malfunction is electrical ‘shorting’ of the commutator segments, this is caused by an accumulation of
“Sludge” within the Control Unit. A DTC is stored when the respective Control Unit does not move through its full range of motion.
Production change
Exhaust Flap Control Unit grease specification updated from VIN 80093
Should any issues be reported post the suggested VIN (80093) please raise a DISS query and await further instruction
Measure
Note:
Right hand exhaust - ECU1 (B1)
Left hand exhaust - ECU 2 (B2)
CAUTION: Ensure the exhaust system has fully cooled prior to working on or around it.
Using the DTC information, conduct a visual inspection of the relative Exhaust Flap Control Unit wiring harness and connector contacts.
Carry out an ignition cycle whilst monitoring the operation of the left and right hand Exhaust Flaps, check for any operating issues.
If an Exhaust Flap is stuck in an open, closed, partially closed position or does not achieve a full range of motion continue to follow the
instructions within this Technical Product Information (TPI) document – figure 1.
Do not monitor the position of the Exhaust Flaps whilst the engine is running.
