TECHNICAL SERVICE BULLETIN

Reference Number(s): SI M12 08 05, Date of Issue: November 2005

MINI:	Cooper with CVT up to 10/03 production
GROUP:	Engine Electrical Systems

SUBJECT

Incorrect DME Programming

MODEL

Cooper with CVT up to 10/03 production

SITUATION

Customers may complain about various intermittent driveability 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 driveability 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.
