"SUBJECT N63: CBS Oil Service Conversion in ISTA/P. The CBS oil service conversion being performed for the N63 Customer Car Package and timing chain check (SI B11 16 14) does not work correctly. It does not change the interval to the desired 12 months/10,000 miles for the vehicles listed above in the specified production ranges. The ""Conversion, oil service 12months/15,000km/10,000 miles"" is working properly for all other N63 vehicles produced after these dates. Incorrect coding data in the current ISTA/P version"
