Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Your VS V8 could have one of the following for no spark:
Faulty coil, coil lead, rotor breakdown, faulty crank sensor (part of distributor), faulty ignition module (mounted on LH strut tower).
The ECM needs to have a DTC check performed and this will tell you which way to go.
IE: if it logs an engine speed DTC, it will be the distributor. If it logs an ignition bypass DTC, it will be the module, if it logs no DTCs, it will be the coil, or lead, rotor button etc.
Hope this helps.
