Looking for the 03C907309M ECU? This Bosch MED17.5.5 numbered 0261S07731 is prepared as IMMO OFF Plug & Play for: VW Passat 1.4 TSI, so it needs no programming or key coding. We check it before dispatch, and the warranty is 6 months.
The ECU is listed for: VW Passat 1.4 TSI. The label numbers decide – OEM 03C907309M and Bosch 0261S07731 must match your ECU. The model and engine size alone are not enough: a different number, e.g. 03C906022AL (0261S04399), means a different version of the ECU.
Fitting means plugging the ECU in where the old one was – no key coding and no programming. It runs without errors after fitting. Cloning the data from your ECU is available on request (send the ECU or files).
A failed ECU can show different symptoms, for example:
Power supply, earth, wiring and fuses can cause similar symptoms – run a diagnosis before replacing the ECU.
