Mercedes-Benz China has decided to recall vehicles that might be given incorrect software calibration number (SCN) coding in recent visit to workshops.

The error could cause various problems in different automobile models. It might disable fuel pump's reaction to car crash, when it was designed to cut off fuel supply. Other problems include ineffective speed limit and fuel meter mistakes.

The recall involves 22 vehicles in China, including R-Class, SLK-Class, GL-Class, C-Class, CLS-Class and S-Class ones, said the General Administration of Quality Supervision, Inspection and Quarantine of China on Friday.

The incorrect coding is caused by a temporary error of central system, which sent incorrect codes to part of online applications from April 15 to 17 and June 5 to 10. The recalled cars would be renewed with correct codes.
