Repair of the injection pump EDC controller - regeneration of diesel electronics

Typical problems with Bosch VP44 drivers

Failure of Bosch VP44 controllers is a common problem in diesel cars. Typical symptoms are:

  • No power or loss of power while driving
  • Uneven engine operation
  • Boot problems
  • OBD2 error codes: P1631 (Opel), 00550 (VW/Audi), P0216 (Ford)

Why does the choice of transistor matter?

There are two types of VP44 drivers, each of which requires anindividually selected transistor. Using an inappropriate transistor will overload the coil and cause it to fail again. At A-Core, we select the transistor based on laboratory measurements.
