BMW Working Hours Reset – Fault 2FA4

Descriere

The BMW Working Hours reset service resets the operating hours counter in the DME to zero, fixing fault 2FA4, which appears on MEVD17, MSD80, MSD81, MSV90 and MEV17.x units. The operation is done at file level, without replacing hardware, with the checksum recalculated.

This way, the BMW Working Hours reset fixes fault 2FA4 without the cost of a new DME and without mechanical work.

What the BMW Working Hours reset fixes

Fault 2FA4 indicates that the maximum number of hours recorded by the DME has been exceeded. The BMW Working Hours reset removes this fault and brings the control unit back to working condition, avoiding the cost of a new DME. The BMW Working Hours reset service is a niche job, with clear demand and few providers.

The work is done exclusively based on the read you send; the car doesn’t need to be present and the DME doesn’t need to be removed if you already have the complete read.
