PSA SID801A ECU Clone & Programming Service

PSA SID801A ECU Clone & Programming

This is a 1-to-1 cloning service for the PSA SID801A diesel engine control unit. When one of these units fails, a bare replacement won’t run until its data is matched to your vehicle — normally a dealer coding and immobiliser-synchronisation job. We read the data from your original SID801A and write it onto a matching replacement, so the unit you get back is a genuine plug-and-play match: no dealer flash, no immobiliser pairing, and no key re-coding after install.

Vehicles this unit may be fitted to

The SID801A is a Continental/Siemens SID common-rail diesel engine control unit. It is fitted to Peugeot 208/308/508 and Citroën C3/C4/Berlingo HDi and BlueHDi diesels.

Exact fitment depends on the engine, transmission, market and model year, so please send us your part and software numbers before ordering and we’ll confirm your unit is an exact match.

Common faults we see

Common diesel-ECU failures include no-start, injector-driver faults, EGR and glow-plug driver failures, limp mode and water-ingress damage. A 1-to-1 clone keeps your VIN and immobiliser data intact on a working unit.

What we copy across

Working from your original ECU, we transfer the complete flash and calibration, your VIN, and your immobiliser (immo) data onto the matching replacement SID801A. Every value lines up with what your vehicle expects, so the cloned unit installs ready to run.

How ordering works

1. Order this service and complete checkout.
2. Ship us both units — your original SID801A and the matching replacement — or drop them off at our Calgary shop.
3. We clone your data onto the replacement and bench-test it, usually within 24 hours of arrival.
4. We return the finished ECU ready to install.

All cloning work carries a 12-month warranty and a 100% money-back guarantee.

Before you order

We need to read your original unit to copy its data, and your replacement must be the correct matching SID801A hardware. If your original is completely dead or you’re unsure the two units match, message us with your part and software numbers first.
