Do not discard the replaced parts. These parts will be requested by the Warranty Parts Return Center
(WPRC).When the defective timing chains are removed from the engine label them with cylinder head
bank (1 or 2) they were removed from.
8. Terminate the diagnostic session so that FASTA data will be transmitted.
9. Program the vehicle using ISTA/P 3.55.1 or a more recent version and retrofit the new engine oil
service interval. The engine oil service interval of the vehicle must be retrofitted to a shorter service
interval of 12 months or 10,000 miles. ISTA/P will automatically reprogram and code all
programmable control modules that do not have the latest software. Perform the programming, coding
and engine oil service retrofit during the same ISTA/P session.
Important note: For F01, F02, F04, and F07 vehicles, check the operation of the trunk release with the
remote. If the trunk does not open with the remote, refer to the special procedure in SI B66 04 15.
Leave the ICOM connected to the vehicle.
For information on programming and coding with ISTA/P, refer to Centernet / Aftersales Portal / Service /
Workshop Technology / Vehicle Programming.
Engine Oil Service Interval Retrofit Procedure (F01, F02, F04, F07, F10, F12, and F13):

Important Note:
The current ISTA repair manual RA11
31 052 "Replacing both timing chains \
PREMIUM" instructs to release
tension on four bearing bolts (indicated
as #1 for cylinders 5 to 8; and #2 for
cylinders 1 to 4) on the engine block.
IT IS NOT NECESSARY TO DO
THIS.
DO NOT release these bolts, because
the bearing bolts are micro-
encapsulated and they would have to
be replaced if loosened up.
The repair instructions will be updated
soon.
