SITUATION
The vehicle will run rough or hesitate when accelerating from a stationary position, and the following fault
code is stored in DME fault memory.

FC 21A02D – Combustion control: valve lift correction when at idle

CAUSE
A software error in the Digital Motor Electronics (DME).

CORRECTION
Update the vehicle software using ISTA 4.10.20 or higher.

PROCEDURE
1. If other faults are stored in the vehicle then perform the applicable test plans for those faults first and
repair the vehicle as recommended.
Do not replace any parts to specifically address DME FC 21A02D – Combustion control: valve lift
correction when at idle.
2. If no other faults are stored in the vehicle or the other faults have already be been rectified, then go to
step 3.
3. Program the vehicle using ISTA 4.10.20 or higher to integration level 18-03-520 or higher.
4. When the vehicle programming is complete the “Reset Valvetronic list adaption” and “Learning
Valvetronic limit positions” test plans must be performed using the following paths in ISTA/D:
Both of the test plans listed below must be completed after vehicle programming, or the fault will
return.

WARRANTY INFORMATION
During this workshop visit, the affected vehicle may also show one or more programming and encoding
Technical Campaign repairs open. The programming and encoding procedure may only be invoiced one
time.
Update the vehicle to the required I-level or higher by performing and submitting for one of the open
Technical Campaigns instead. Please be sure to also perform any additional work (before and/or
after) the campaign repairs require and/or close the remaining open programming and encoding
Technical Campaign repairs as outlined in the corresponding Service Information Bulletin.
Then, either in conjunction with performing these open Technical Campaign repairs or as a standalone
repair (vehicles without an open programming and encoding Technical Campaigns), perform and claim the
Reset Valvetronic list adaption and Learning Valvetronic limit positions test plans as outlined below.

If you are using a Main labor code for another repair, use the Plus code labor operation 00 00 556 instead of
00 00 006.
Refer to AIR for the corresponding flat rate unit (FRU) allowances.
Work time labor operation code 11 99 000 is not considered a Main labor operation. Also, since the work
time FRU allowance to be claimed is specified, a separate punch time is not required. However; it still
requires an explanation on the repair order and in the claim comments section.
Programming and Encoding - Vehicle Control Units (RO and Claim Comments Required)
The programming procedure automatically reprograms and encodes all vehicle control modules which do
not have the latest software I-level. If one or more control module failures occur during this programming
procedure:

Please claim this consequential control module-related repair work (including performing the IRAP
Control Unit Recovery procedure first as required, refer to the SIB in AIR) under the defect code listed in
this bulletin with the applicable AIR labor operations.
Please explain this additional work (The why and what) on the repair order and in the claim comments
section
For control module failures that occurred prior to performing this programming procedure:

When covered under an applicable limited warranty, claim the applicable test plan and the corresponding
control module-related repair work using the applicable defect code and labor operations in AIR
(including diagnosis with separate punch times).
