Bentayga W12 - Engine control modules - Software update - Emission service action (SC 20/07)

Notes

Transaction No.: 2058667/4

Repair instructions

Technical background
Due to sub-optimal configuration of the OBD (On Board Diagnostics) system, which monitors emissions controlling components within the engine
and exhaust system, some of the components may not be monitored as frequently as stipulated by the federal regulators
The software additionally addresses concerns where the engine control modules display the following DTC's
Diagnostic address

Event memory entry

0001 - Engine Control Module 1 P008700: Fuel Rail/System Pressure - Too Low
0001 - Engine Control Module 1 P008800: Fuel Rail/System Pressure - Too High
0001 - Engine Control Module 1 P013300: O2 Sensor Circ.,Bank1-Sensor1 Slow Response
0011 - Engine Control Module 2 P008700: Fuel Rail/System Pressure - Too Low
0011 - Engine Control Module 2 P008800: Fuel Rail/System Pressure - Too High
0011 - Engine Control Module 2 P013300: O2 Sensor Circ.,Bank1-Sensor1 Slow Response
The software also reduces the excess build up of engine oil within the charge air cooler system
IMPORTANT: A specific level of oil residue is expected in a charge air cooler, however if any amount of oil is found within the charge air coolers
OR any of the previously mentioned symptoms within the Customer statement/workshop findings section are evident the operative must
determine which section is applicable
The operative MUST only conduct
Section 1
Or
Section 2
Do Not under any circumstances conduct both sections as this is not required
VERY IMPORTANT:
Conduct Section 1 ONLY - For vehicles with a customer complaint or an observation by the retailer that the engine has
operation issues for example - Not running smooth - Rough running – Misfires – Related DTC’s and/or the emission warning light is
evident within the drivers information panel
Or
Conduct Section 2 ONLY - For all other vehicles which DO NOT exhibit any of the previously mentioned symptoms/engine
operation issues

NOTE: Although no issues are evident in this scenario the instructions within section 2 MUST be followed to completion
including the application of the emission software update

Remedy
Software update for the engine control modules

Customer notification
Customers of affected vehicles will be notified in writing by Bentley Motors.
Please ensure that all affected vehicles are checked and repaired during the next workshop visit, make a note of the required emission service
action on the workshop order before it is signed by the customer.
If it is omitted to perform the work required for the emission service action during a workshop visit, the customer should be notified immediately.
You should also pass on this information to your new and used car sales departments so that vehicles affected are checked and if necessary
repaired immediately.

Check
If the vehicle is not already listed as repaired in the ‘Repair history’ section of Elsa Pro, check for the presence of the red completion mark (Refer
to the Identification section). In the event the emission service action has not been applied, please carry out the required work in accordance with
these instructions.

Control
All VIN applicable vehicles as per Elsa Pro must have the required work conducted

Work
Section 1
Please read carefully to confirm/clarify you are conducting the correct section NOTE: Do Not conduct both sections

Section 1 – Must be conducted on vehicles with a customer complaint or an observation by the retailer that the engine has
operation issues for example - Not running smooth - Rough running – Misfires – Related DTC’s and/or the emission warning light
is evident within the drivers information panel
IMPORTANT: Prior to starting this procedure the fuel tank MUST be full
1) Remove the front undersheet – Refer to Rep.Gr 66
•

Referring to Figure 1 - Remove the right and left hand lower charge air cooler pipes, any oil found in the charge cooler/pipes should be
drained off, any remaining oil residue should be cleaned from the charge coolers and pipes

•

Refit the lower charge air cooler pipes

Figure 1

2) Check and if necessary correct all engine fluid levels (Coolant/engine oil)
•

Check the fault memory of both engine control modules for either of the following DTC’s

- Address 01 - Engine Control Module 1
“P010600: Manifold Absolute Pressure or Bar. Pressure Sensor Circuit Range/Performance”
Or
- Address 11 - Engine control Module 2
“P2A0B00: Manifold Absolute Pressure Sensor "B" Circuit Range/Performance”
If either of the DTC’s are stored, remove the relevant sensor (G429 or G71) and check for oil contamination in the sensor (Figure 2). If found to
be contaminated replace the affected sensor - Refer to the ETKA parts catalogue

Figure 2
3) Refit the front undersheet
4) Software update
•

The closed- circuit voltage of the vehicle must be at least 12.5 V during the update. Connect a suitable battery charger
to the vehicle. For further information refer to the Repair manual.

•

During the update switch off all unnecessary consumers ( ventilation, seat heater, interior illumination etc)

•

Because of the highest transmission stability you MUST use the diagnosis interface VAS 6154 ( WiFi diagnostic tool)
ONLY in USB operation or the cable- connected VAS 5055 for the reprogramming ( updating) of control units. If these
units are not available, the diagnosis interface VAS 5054 ( A) can also be used in USB mode

•

Do Not under any circumstances use a Bluetooth connection to conduct the reprogramming ( updating) of control units

5) Place the ignition key in the remote control key reader and switch on the ignition - Figure 3

Figure 3
6) Select and run Guided fault finding

•

Within the Special functions tab select SVM – Problem related Hardware/Software update then select Perform test (Figure 4)

Figure 4
7) On the next screen enter the SVM code 4V0ECMTF 01 and select Adopt (Figure 5)

Figure 5
•

On the following screen, confirm the SVM code is correct and select Yes.

•

All control modules will now be interrogated.

•

The software update will then be suggested, select Yes.

•

The software of the 01 – Engine Control Module 1 and 02 – Engine Control Module 2 will then be updated individually, a progress bar will
be displayed

•

Once the software update is completed for both engine control modules, a confirmation screen will be evident to clarify the update has
been successful (Figure 6)

Figure 6
8) Add the relevant dose of G17 Fuel additive as specified on the bottle

•

Run the engine at idle for 8 hours – Periodically check to ensure engine coolant temperature is within safe limits – do not allow the
engine to overheat

9) Check and confirm that no DTC’s are stored or there are no engine operation issues evident prior to starting the procedure from step 10 –
Save an online log to confirm that no DTC’s were evident at this stage of the procedure
VERY IMPORTANT: The operative conducting this procedure must be aware of the following whilst the vehicle is undergoing this procedure
during the current workshop visit
•

Do not attempt to erase any DTC’s from the engine control module/s and transmission control module

•

VERY IMPORTANT: Do not conduct a readiness test other than when instructed within this procedure

•

Do not disconnect the battery whilst the CAN BUS is awake

•

Failure to comply with any of the above will erase the previously set engine adaptions, therefore the complete process
will require repeating

CAUTION: Ensure that any outstanding issues are resolved before commencing
IMPORTANT: Ensure that before the next part of the procedure is conducted (engine DTC adaptions clear) the engine must be at
operating temperature (>90C)
