Displayed Range Is Lower After Programming (61 35 14)

DISPLAYED RANGE IS LOWER AFTER PROGRAMMING

TECHNICAL SERVICE BULLETIN

This Service Information bulletin supersedes SI B61 35 14 dated May 2015. 

SUBJECT

Displayed Range Is Lower After Programming 

SITUATION

After the vehicle is programmed with ISTA/P 3.53.3 (i-level I001-14-07-503), the displayed vehicle range in the instrument cluster is lower than prior to the software update. The actual range that the vehicle is capable of achieving on a full charge has not changed.

The difference between the displayed range and actual range is always conservative, yet this difference varies based on driving profile. When driving primarily at highway speeds, the difference between displayed and actual range is within a few percent of each other. When driving primarily with a low speed/city profile, the gap may widen to as much as 20% or more.

Software improvements have been made to the range algorithm to improve its accuracy in all driving scenarios. These updates are available with ISTA/P 3.55.0 (I-level I001-15-03-501). In addition, the following enhancements are integrated into this new I-level:

• The state of charge (SOC) percentage is visible in the upper left corner of the Kombi. It has been added to the board computer display in order for the customer to better manage the vehicle range.
• On vehicles from 3/2015 production, hospitality charging (charger sharing) has been added. This feature will automatically unlock the charge port when the vehicle is fully charged and still plugged in. This feature is not backwards-compatible to vehicles produced prior to 3/2015.
• REx only - if the SOC reaches 2.0% with the REx running, the message "Low Battery. Power Reduction Possible." will appear in the Kombi.

In addition to the range display, the customer may notice that the vehicle's range has decreased as outside temperatures have gotten colder. This is most noticeable in extreme cold climates, and when preconditioning is not used. This situation does not indicate a problem and is independent of the range display algorithm.

CAUSE

The algorithm that determines the displayed range, was changed with the 14-07-503 software level. The result of the changed algorithm is that the display is too conservative.

PROCEDURE

Only properly trained personnel, who have passed all applicable technical training courses, should perform any maintenance or repairs on any Hybrid or Electric Vehicle. Work performed by unqualified persons may result in severe injury or damage to the vehicle. Additional information may be found in REP 61 00... Observe safety instructions when handling electric vehicles. 

Program and code the entire vehicle using the latest version of ISTA/P (3.55.0 or higher). Target integration level I001-15-03-501 or higher.

Always connect a BMW approved battery charger/power supply (SI B04 23 10 ).

For information on programming and coding with ISTA/P, refer to Centernet/Aftersales Portal/Service/Workshop Technology/Vehicle Programming.

If the customer believes the actual range has degraded considerably and is prior to the release of the improved software, submit a PuMA case entitled "i3 Range Display Accuracy" for further assistance.

BMW I CHARGEFOWARD PROJECT

BMW has identified "85" vehicles that may require a software update procedure to be performed as outlined and in conjunction with this bulletin.

To assist you in identifying these vehicles, the DCSnet Warranty Vehicle Inquiry has been updated with the "Vehicle Comment" shown below:

This vehicle is part of the "BMW i ChargeFoward" project. This vehicle's integration level may not be at "I001-15-03-502 or higher" as required, please program and code this vehicle using the latest version of ISTA/P. This work is covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks or the BMW Certified Pre-Owned Program. Please see SI B61 35 14. No repair is necessary if the vehicle is already at or above the "noted" integration level. 

A VIN list is also attached.
