SITUATION
The customer complains that one of the following scenarios has been encountered while operating the vehicle:
^ During a cold start in the morning, the engine runs very roughly and the Service Engine Soon lamp is illuminated.
^ During a hot start, the engine runs very roughly and the Service Engine Soon lamp is illuminated.
^ While driving or idling, the engine will misfire and the Service Engine Soon lamp is illuminated.
^ Various misfire faults are stored in DME fault memory.
CAUSE
An internal failure of the high-pressure fuel injector can lead to incorrect operation.
PROCEDURE
Always diagnose the vehicle using the misfire test plan "AT1214_DI8MISFIRE - Misfiring detection" first.
After completion of this test plan, repair the vehicle as directed before performing any other suggested engine or fuel system-related test plans, e.g.,
"AT1214_DI8KHDR - High-pressure fuel system", "AT1214_DI_GEM - Mixture adaptation", etc.
If applicable, injector test plans "B1214_DI8INJ1_4 - Injectors, cylinder 1-4" or "B1214_DI8INJ1_8 - Injectors, cylinder 5-8" state to perform
service function "AS1214_DI8IGS (injector equalization)," when completed.

Note:
Performing the injector equalization is not intended for vehicles with the N63 engine. This is a diagnostic software error that can be ignored.
This error will be repaired in ISTA/D 2.35.
When the ISTA system message displays: Battery voltage only "XX.XX" V. Please connect charger. Please note the displayed battery voltage
reading in the repair order comments section. This documentation is not necessary when part of an approved Technical Service repair procedure; the
battery charger is required to be attached before performing the Vehicle Test.
Failure to diagnose the engine or fuel system issues in this order can cause an incorrect diagnosis and repeated repair attempts.
1. Terminate the diagnostic session and proceed to step 2.
2. [NEW] Remove the spark plugs and inspect them for over-fueling; compare the color and smell.
a. If at least one of the spark plugs appears to be wet with fuel, replace all eight (8) high-pressure fuel injectors.
b. If none of the spark plugs are wet with fuel, proceed to the next step.
3. Perform the applicable test plan for the misfire fault stored.
If a misfire fault is not stored but a reproducible customer complaint does exist (e.g., rough running shaking, loss of power, etc.), perform the
misfire test plan "AT1214_D18MISFIRE - Misfiring detection".
Follow the procedure below to locate and start the Misfire test plan.
Select "Function Structure."
Select "01 Engine."
Select "Engine electronics, quality control valve (MSV)."
Select "Misfire Detection."
Select "Start search."
Select "AT1214_D18MISFIRE - Misfiring detection."
4. Perform each step of the test plan as directed.
5. In order to bypass the fuel system test plans you must answer "YES" to the following question in the Misfire test plan:
"Has troubleshooting on the following function or component group been conducted in response to a misfire fault?"
6. At the conclusion of the test plan the following question may be displayed "Have injectors already been replaced due to misfires within the last 4
months? Select "NO" and continue.

Labor operation code 00 00 006 is a main labor operation. If you are using a main labor code for another repair, use the plus code labor operation 00
00 556 instead.
Even though work time labor operation code 61 00 006 ends in "006," it is not considered a Main labor operation.
Work time (WT) labor operation 61 00 006 requires an individual punch time. and
Performing Procedure Steps # 1 and # 2 (The "misfire" test plan advises you to perform any "fuel system" test plans)
Refer to KSD2 for the corresponding flat rate unit (FRU) allowance. Enter the Chassis Number, which consists of the last 7 digits of the Vehicle
Identification Number (VIN). Click on the "Search" button, and then enter the applicable flat rate labor operation in the FR code field.
Other Repairs
If performing other ISTA diagnostics and their related test plans results with eligible and covered work, claim this work with the applicable defect
code and labor operations listed in KSD2.
Note:
Please follow any TeileClearing (TC) or Diagcode (DC) requirements that may apply to this additional work.
