Questions about this file
Is this original file compatible with my Mercedes-Benz BUS?
Read the ECU identification with your tool (hardware and software numbers) and send it to us with the order; we confirm the exact original before delivery. Temic / Continental MR, MCM, ACM and CPC controllers (Mercedes-Benz) use A-part numbers such as A0024461235ZGS002; the ZGS suffix is the release state of that part.
What exactly do I receive when I buy the Temic OM457LA original for €25?
An unmodified factory read of the Temic OM457LA (identified on this page) as stored in our archive — a binary file in the format produced by the original reading tool, chosen among the 4 reads listed on this page after we match your identification. No modifications, no checksum changes: it is meant to restore the ECU to its stock calibration or to serve as a reference for a tuning job.
How and when is the file delivered?
After payment we confirm the read matches the numbers on this page and release it to your account, with an email notification — usually within 3 hours, within 24 hours on business days. If your ECU reports different numbers, tell us with the order and we look for the right file before delivering anything.
Can you also tune this Temic OM457LA or remove EGR / AdBlue / DPF?
