•
•

Clear all fault codes
Allow the CAN to go to sleep
Test drive the vehicle and see if the complaint is still present
•
If the complaint is no longer present, release the car
•
If the complaint is still present proceed with the following steps

Perform the Following:
1) Smoke test intake/exhaust and check for leaks.
1.
2.
3.
4.
5.

6.
7.
8.
9.

•
•

•

•

Working each bank one at a time; remove the upstream O2 sensor and install the smoke tip. Seal around the tip
to ensure there are no leaks.
Seal the exhaust tip outlet to the O2 sensor bung
Turn the smoke machine on at the maximum possible pressure.
Look for leaks in the exhaust
Using very soapy water (it should create suds by itself by spraying) saturate all connections.
•
Look for signs of bubbles
•
Move and stress the components
•
Perform the check with engine cold and after a 5 minute run time (lukewarm)
Working each bank one at a time, Install the smoke machine tip into the intake air temperature sensor port
Remove the oil fill cap
Turn the pressure up on the smoke machine to maximum and fill the engine with smoke until it begins to come
out of the oil fill port.
Reinstall the oil fill cap
Look for leaks
Using very soapy water (it should create suds by itself by spraying) saturate all connections.
•
Look for signs of bubbles
•
Move and stress the components
•
Perform the check with engine cold and after a 5 minute run time (lukewarm)
If leaks are found, perform the following:
Repair the leaks as necessary.
Clear the mixture adaptations and clear the fault codes
•
Read out the injector performance data. Label this as IPDA
•
Read out the line graph version of the fault counter per the attachment "Fault Counter Instructions". Label
this FCA
Perform 2 AMG Engine Adaptation Drives
•
Rear out the injector performance data again. Label this IPDB
•
Rear out the line graph version of the fault counter per the attachment "Fault Counter Instructions". Label
this FCB
Upload IPDA, IPDB, FCA, and FCB to a PTSS case.

2) Check driver's side intake manifold for cracks near the rear (see attachments) of the engine.
•
1.
2.

If damage is found, order a new manifold for the driver's side bank from EPC and OPEN PTSS case with pictures of damage. Include the following:
Production stamp on the damaged manifold (looks like a pair of clocks)
Production sticker

•

If no damage is found, or repair does not remedy complaint proceed to step (3).

3) Inspect ignition coils and verify they are PN: A 177 906 95 00.
•
•

Replace as necessary.
If all coils are PN A 177 906 95 00 swap the coil(s) of the misfiring cylinder(s) with those of cylinder(s) that are
not misfiring and road test the vehicle.
•
If the misfires move with the coils, replace the coils and the spark plugs on original misfiring cylinders
•
If the misfires do not move with coils or do not immediatley reappear proceed to step 4

4) Measure the following grounds. If any reading is above 0.5 ohm, check grounding locations (per attachments)
•
•
•
•
•
•
•

ME Connector F, Pin 1 to ground
ME Connector F, Pin 2 to ground
ME Connecter F, Pin 4 to ground
ME Connector M, Pin 6 to ground
ALL Coils, Pin 1 to ground
Rework grounding locations by removing and cleaning the chassis ground point(s) of any paint or debris.
If rework/replacement does not remedy complaint, proceed to step 5.

5) Perform a Xentry guided high pressure fuel test from cold start and obtain the injector performance data, and initial
quick test with fault freeze
•
•

If the test fails for either bank, replace the high pressure fuel pump for that bank.
If the test passes for both banks, road test the car with ECO start/stop disabled and allow the vehicle to achieve
operating temperature
•
Shut the vehicle down and observe the fuel pressures on the left and right banks at t=0, t=30 minutes, t=60
minutes, and t>120 minutes
•
If at any time the fuel pressure drops below the minimum value and/or a large differential exists between the left and right banks (> 45 bar), boroscope the cylinders on the bank with low fuel pressure
and determine if one or more of the injectors is leaking.
•
If the fuel pressure remains within acceptable limits proceed to step (6)
•
If one or more of the injectors is leaking, open a PTSS case and upload pictures of the failed
injector(s) taken with the boroscope as well as the information collected via Xentry thus far
•
Replace the failed injector(s) and all the injector seals
•
Update the IMA coding for the new injectors in their respective cylinders via Xentry
•
Perform an AMG engine adaptation drive (at least 50 miles total)
•
Upload the new injector performance data and quick test to the case
•
Road test the vehicle. If the complaint is no longer present the PTSS case can be closed and
the vehicle released.

6) Open PTSS Case if Above do not Remedy the Complaint
Include in the case:
1) All Data from step (5)
2) MED1775 Control Unit Log
3) Software update check for ME and Transmission control units
5) Engine Performance Data
6) Injector Performance Data
7) Line Graph Version of the Fault Counter from Cold Start
8) PICO Compression Test of ALL Cylinders
9) Boroscope of MISFIRING Cylinder(s)
