Technical product information
Multiple random misfires evident during PDI

Transaction No.: 2068273/3
Release date: 29-Sep-2023

Customer statement / workshop findings
Multiple random cylinder misfire DTC’s detected during PDI - DTC P030000: Random/Multiple Cylinder Misfire Detected (misfires on multiple
cylinders) within the following control units:
•

V8 - ECM 1 - V8 (Address 01) ECM control unit

•

W12 - ECM 1 - (Address 01) and/or ECM 2 (Address 11)

Technical background
The anti-foul fuel which is added during the manufacturing process can cause the described symptoms
HINT: This is dependent on how long the anti-foul fuel has been stored within the fuel tank
In the event the symptoms are as described please refer to the Measure section of this TPI

Production change
Not Applicable.

Measure
1) Using ODIS - Confirm the amount of anti-foul fuel which is within the fuel tank
•

Select Engine control module 1

•

Select Guided functions - Navigate to the MWB which details the level of fuel which is in the tank

IMPORTANT: If there is 10 litres of fuel within the tank (at the point of conducting the PDI) the operative must add double the amount of correct
octane fuel, in this scenario the operative must add 20 litres of the correct octane fuel which would equate to a total of 30 litres of fuel in the tank
2) Refer to one or a combination of the following:
•

Fuel filler flap label

•

Owners handbook

•

Elsa pro

3) Add the required amount of fuel (as described in step 1)
•

Park the car in a well ventilated area ensuring suitable exhaust extraction is available and used at all times

•

Allow the engine to idle for 30 minutes in a well ventilated area VERY IMPORTANT: Whilst the engine is idling the operative MUST check
to confirm the engine is operating to specification and also check to confirm there are no warnings evident within the DIP whilst the engine
is idling in particular engine overheating warnings/issues

IMPORTANT: The vehicle must be parked on a suitable hard surface ensure no combustible or flammable materials are in
the vicinity of the vehicle/underside of the vehicle
•

After 30 minutes has elapsed monitor the misfire counts for all cylinders using ODIS

•

W12 - Measured values ECM 2 (Address 11) - Misfire counters

•

V8 - ECM 1 (Address 1) - Misfire counters

•

Clear all applicable DTC’s

4) Select Engine control module 1 - Using Guided functions - Reset the readiness code - Select Readiness code - follow all onscreen prompts
until complete
•

Once complete check and confirm the actual readiness code, should the readiness code bytes be 00000000 NO FURTHER ACTION IS
REQUIRED

Should ANY of the bytes be 1, YOU MUST repeat the readiness code test. Once complete you must then recheck and confirm the readiness
code is 00000000
5) Monitor the misfires counts for all cylinders - If no misfires are evident conduct the PDI road test
•

On return re-check for multiple cylinder misfires

INTERNAL

6) In the event the issue is no longer evident no further action is required
However
In the event the issue is still evident the operative should raise a technical DISS query (ensure a current ODIS log is attached) await feedback
before conducting any further work
