Important Notes & Buyer Tips
Make sure the part number on your original ECU exactly matches one of: 0261S06620, 9676379780, or 9666319180. Many listings emphasise these codes.
Even with matching part numbers, software version, engine variant, and immobiliser coding might differ — verify compatibility before purchase.
After installation, clear all fault codes and check that the engine runs properly (idle, sensor readings, diagnostic connectivity).
Request photos of the ECU’s label and connector to ensure correct hardware version and condition (no water damage, corrosion, burnt pins).
Because this ECU comes from a vehicle with anti-theft/immobiliser systems, some installations may require programming by a qualified technician or dealership.
