Chronology :

On June 22, 2022, BMW became aware of a BMW electric vehicle at a dealer in China which contained a warning lamp regarding a drivetrain issue. Diagnostics indicated that the issue pointed to the high voltage battery electronic control unit. An engineering review was initiated.

Various tests and analyses were conducted including software and hardware tests, and a review of field data.
Laboratory and road tests were performed. Field monitoring at that time did not indicate that any vehicle had experienced a permanent (i.e., no ability to restart) loss of power. The analyses indicated that the warranty claim rate was less than 0.1%, although there were no known cases in the US market. Nevertheless, the engineering review and field monitoring activities continued.

In August and September, additional warranty cases involving a temporary (i.e., ability to restart) loss of power became known, but the rate was still well below 1%. Approximately five cases were received in the US. At that time, there were no known incidents involving a permanent loss of power. Analyses and testing continued.

By late November, approximately five additional warranty cases in the US became known, and results from additional tests and analyses were available. It was suggested that, during certain vehicle operating conditions, an increase in cases involving loss of power could occur over time.

Vehicle assembly information and supplier production and process records were reviewed to determine the number, and production dates, of potentially affected vehicles.

On December 13, 2022, BMW decided to conduct a voluntary safety recall.

BMW has not received any reports, nor is BMW otherwise aware, of any accidents or injuries related to this issue.

BMW Diagnostic & Reprogramming

Introduction

The Online Service System (OSS) has been developed specifically for independent automotive workshops to provide an extensive range of resources. The following applications are available in the OSS:

 

ISTA Diagnosis Application

Vehicle diagnostics from the Z3/E36, with the BMW ICOM, or with a J2534 pass-thru tool (from model year 1996).

  • Fault Code Diagnosis
  • Test Plans
  • Repair Instructions (E30 or higher)
  • Technical Data
  • Wiring diagrams

 

Web ISTA Information Application

WebISTA has been developed to provide an information only application for users that do not require all of the services included in the ISTA diagnostics application.

  • Repair Instructions (E30 or higher)
  • Technical Data
  • Tightening torques
  • Wiring diagrams

 

You can search using document title, document number and subject areas as the search criteria. The desired information is displayed by means of graphics and explanatory text.

 

ISTA/P Online - Control Module Reprogramming

With ISTA/P you can reprogram the onboard control modules that are capable of software reprogramming.  For ISTA/P, a data interface, a power supply and an Internet connection are required. The data interface can be a BMW Group ICOM interface or a "Pass-Thru Tool (PTT)" that fulfills the requirements of the SAE J2534 standard.

 

What is needed to diagnose and program with the BMW OSS?

The OSS consists of a desktop or laptop PC connected to BMW over the Internet. To connect to the vehicle you can use the BMW authorized diagnostic interface "integrated communication optical module (ICOM)" or use a J2534 "Pass Thru Tool (PTT)".
