CORRECTION

1. Perform a vehicle test with ISTA to identify fault code entries.
2. Work through the corresponding test module.
3. Program and encode the vehicle with the latest version of ISTA (e.g., 4.21.1x, available December, 2019 or higher) to integration level F056-16-11-501 or a higher version.

Important warning for working on the high-voltage systems on the i3: 

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 is found in Repair Instruction 61 00... Observe safety instructions when handling electric vehicles. 

PARTS INFORMATION

Not required.

WARRANTY INFORMATION

During this workshop visit, the affected vehicle may also show one or more programming and encoding Technical Campaign repairs open, the programming and encoding procedure may only be invoiced one time.

Update the vehicle to the required I-level or higher by performing and submitting for one of the open Technical Campaigns instead. Please be sure to also perform any additional work (before and/or after) the campaign repairs require and/or close the remaining open programming and encoding Technical Campaign repairs as outlined in the corresponding Service Information Bulletin. 

In conjunction with performing these Technical Campaign repairs on the vehicle, if needed for the repair described in this bulletin, claim the diagnosis portion provided below (excluding the flat rate labor operations for battery charging, programming and encoding) together with a corresponding explanation on the RO and in the claim comments.

Only if the above situation does not apply, the BMW software solution is then:

Covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks or the BMW Certified Pre-Owned Program as described below.
