Servicing Cruise


- On TDI models, cruise control system functions are controlled entirely by the Diesel Direct Fuel Injection (DFI) Engine Control Module (ECM) -J248-.

- The only additional component is the cruise control switch (integrated with the turn signal switch). The function of the cruise control switch is monitored by the Diesel Direct Fuel Injection On Board Diagnostic (OBD).
