NOTE: Should the issue/s described within this TPI be evident and the vehicle is post the advised VIN cut off please raise a DISS query and await
feedback before conducting and further work

Service
VERY IMPORTANT: Prior to conducting the onward instructions, the following symptoms MUST be evident
•

Warning on Driver Instrument Panel (DIP) “Oil pressure too low ”

And/or
•

Diagnostic Trouble Codes (DTC) “P052400: Engine Oil Pressure Too Low” and/or “P15AA00: Engine oil pressure - Lower limit not
reached” stored in the Master Engine Control Unit (ECU)

Should any of the afore mentioned not be evident and the symptoms cannot be reproduced – No further action should be taken unless the issue
can be reproduced or demonstrated by the customer
In the event the symptom/s are evident please conduct the onward Diagnosis Instructions

Diagnosis Instructions
With a confirmed Customer complaint of low oil pressure warning displayed on the DIP and Diagnostic Trouble Codes
“ P052400: Engine Oil Pressure Too Low” and/or “P15AA00: Engine oil pressure - Lower limit not reached” stored in the
Master ECU - Raise a full technical DISS query and proceed with this document, ensuring a detailed customer description
regarding the issue is added or included to new or the existing DISS query
Step 1
Is this a repeat visit for the same low oil pressure concern?
Yes – Continue to Step 2
No – Follow ALL remaining instructions to completion
•

Using the Bentley approved diagnostic tool take a vehicle Diagnostic log and attach to the DISS query.

•

Read and record Measured Values IDE02756 and IDE02757 as follows:

NOTE : - Measured Values IDE02756 – “Number of manual engine starts” and IDE02757 – “Number of automatic engine starts” are currently only
available for Continental and Flying Spur series vehicles, DO NOT attempt to record Measured Values for Bentayga.
Using the Bentley approved diagnostic tool.
•

Select “Start Diagnosis” and follow the on screen prompts.

•

Select “Control units” and then “Engine Control Module 1 (01 – Engine Control Module 1)” – Figure 1.

Figure 1
•

“Right click” on “Engine Control Module 1 (01 – Engine Control Module 1)” and select “Guided functions” – Figure 2.

Figure 2.
•

Select “Read measured values” and then “Execute” – Figure 3.

Figure 3
•

Select “IDE02756” and “IDE02757” and then “OK” – Figure 4.

Figure 4
•

Note the values of “IDE02756” and “IDE02757” and add this information to the DISS query, select “OK” – Figure 5.

Figure 5
•

Select “Done/Continue” and then exit the application – Figure 6.

Figure 6.
•

Check and confirm the engine lubricating oil level is correct, refer to Repair Group 17 Engine Lubrication / 6.0L W12 TSI / Engine
oil – To check – add result to the DISS query.

•

Measure the actual engine lubricating oil pressure, refer to Repair Group 17 Engine Lubrication / 6.0L W12 TSI / Engine oil
pressure – To check - add result to the DISS query.

Oil pressure values are:
Engine Speed

Minimum Oil Pressure (bar)

Permissible Tolerance (bar)

600 rpm (idle)

1.3

+/

- 0.3

2000 rpm

1.6

+/

- 0.3

Note: Always refer to the Electronic Workshop Manual (Elsa-Pro) for current minimum oil pressure values.
Is the oil pressure low?
Yes – Proceed to Step 2
No – Conduct a road test, as follows:
•

The road test should be a minimum of 30km (18.6 miles)

•

Drive the vehicle until normal Engine coolant operating temperature is achieved of 90oC

•

The following procedure will cycle the engine lubricating oil pump from low duty to high duty:-

•

Observing local highway rules and regulations, find a safe and suitable location to conduct the following:-

•

Place the transmission selector lever into Manual gear mode “M”, proceed to drive the vehicle, use the steering wheel gear selector
paddles to select gears, when in second gear gently accelerate from 1500rpm to 4500rpm holding second gear, repeat this procedure
fifteen times.

•

Using transmission Drive mode “D” and sport mode, observe local highway rules and regulations, accelerate from standstill whilst
depressing the accelerator pedal a maximum 25 to 50% of travel - repeat five times. Do not use 100% accelerator pedal input
during this test.
Caution: For New Continental Series vehicles

•

If Sport mode is selected on the drive dynamics control, the Electronic Stability Control (ESC) is switched off, if the driver has selected
manual gear mode “M” the transmission will not automatically up shift to the next gear.

Has the issue cleared?
Yes – No further action is required.
No – Proceed to Step 2

Step 2
Refer to Repair Group 17 Engine Lubrication / 6.0L W12 TSI / Engine oil and filter – To renew.
•

The engine lubricating oil should be drained through a fine gauze filter, once fully drained check the engine oil filter and fine gauze filter for
contaminants or particles IMPORTANT – Regardless of findings place the engine oil filter and gauze filter into a clean sealed container and
retain for possible analysis IMPORTANT: Take clear photos of any contaminants or particles found

•

Remove the Valve for Oil Pressure Control N428 (Refer to Figure 7 for fitting location) - When the valve has been removed carefully
examine it and the associated location on the engine for any signs of internal contamination, debris or damage.

Figure 7
•

Should NO contamination, debris or damage be found – Refit N428

•

Replace engine lubrication oil and filter - Refer to Repair Group 17 Engine Lubrication / 6.0L W12 TSI / Engine oil and filter – To renew.

Was debris found in the Engine oil – Oil filter or Oil pressure control valve?
Yes - Seek further advice via the DISS query.
No – Carry out a road test as follows:
•

The road test should be a minimum of 30km (18.6 miles)

•

Drive the vehicle until normal Engine coolant operating temperature is achieved of 90oC.

•

The following procedure will cycle the engine lubricating oil pump from low duty to high duty:-

•

Observing local highway rules and regulations, find a safe and suitable location to conduct the following:-

•

Place the transmission selector lever into Manual gear mode “M”, proceed to drive the vehicle, use the steering wheel gear selector
paddles to select gears, when in second gear gently accelerate from 1500rpm to 4500rpm holding second gear, repeat this procedure
fifteen times.

•

Using transmission Drive mode “D” and sport mode, observe local highway rules and regulations, accelerate from standstill whilst
depressing the accelerator pedal a maximum 25 to 50% of travel - repeat five times. Do not use 100% accelerator pedal input
during this test.

Caution: For Continental Series vehicles
If Sport mode is selected on the drive dynamics control, the Electronic Stability Control (ESC) is switched off, if the driver has selected manual
gear mode “M” the transmission will not automatically up shift to the next gear.
Is the Low oil pressure warning resolved?
Yes – No further action required.
No - Seek further advice via the DISS query.
