DAF LF, CF, XF Truck Fault Codes DTC (ALS, AGS) 17-19. Internal fault in the VIC unit: - Short-circuit on the power supply at terminal block B16 ALSS. Improper activation of the hazard warning lights or the lack thereof. The alarm system is not activated. If the Emmission Control Light and/or the Engine Managment warning light come on at the same time as the DPF there's a more serious fault. At this point you should contact your recovery company or Volkswagen Assistance on 0800 777192 if your VW is under 1 year old (Phaeton & Touareg have a 3 year breakdown cover). All dash symbols are coded in three basic groups for initial indication - red, yellow/orange, green/blue similar to the traffic lights. Red - potentially serious problem / system failure or safety issue. Also it could show important reminder. Yellow/orange - indicates upcoming servicing or system repair. If any of the symbol is flashing please. The warning symbol in the display of the DIP will then appear in red. The 'STOP' warning indicator will also light up. Driving is therefore no longer possible! If the fault is one whereby the gearbox may still be shifted, the warning in the main display will disappear. The ECU will have recorded the fault as an inactive fault.
