SUBJECT
Incorrect DME Programming
MODEL
Cooper with CVT up to 10/03 production
SITUATION
Customers may complain about various intermittent drivability problems, mainly, engine speed fluctuation when coasting down to a stop or when
accelerating from a stop with engine fully warmed.
CAUSE
Incorrect programming numbers in the EMS2K (DME) control module.
The manual determination programming procedure for MY' 02 / '03 R50 CVT vehicles was not followed during the DME reprogramming, resulting in a
wrong calibration version installed.
The correct procedure for DME programming is provided in SI M12 02 03 and M12 01 04.
CORRECTION
When diagnosing Cooper CVT drivability complaints, first verify the EMS2K Programmed and Basic Part Numbers.
For the MY '02/'03 MINI Cooper with CVT, the latest (as of CD 43) correct DME Part Numbers should be:
^
Programmed - 7547052
^
Basic - 7527610.
IMPORTANT:
If the EMS2K Programmed Part Number is found to be: 7539191, or 7542746, or 7547050, then the control module had been reprogrammed with
calibration for the manual transmission vehicle, and needs to be manually reprogrammed using the procedure below.
PROCEDURE
To reprogram the EMS2K control module on Cooper CVT UP TO 10/03 production vehicles:
1.
Connect a battery charger.
2.
