All 4th generation gasoline engine Jettas and Golfs are wired the same in this regard, the power supply relay seems to be faulty. It is really number 12 on the relay panel.Before you replace that you should check that the main fuse box on top of the battery is okay, sometimes the alternator cable fails and get so hot it melts the fuse box and that's what supplies power to these relays.I have enclosed a picture of the relay panel.If I have helped answer your question your satisfaction please remember to hit accept cuz that's the only way that I'm compensated for my time.If you have any follow-up questions please let me know, you can ask even after hitting answer.

Hi Danny its more then that i have no power to fuse 10, 29,32 and 34
fuses on top of battery have been checked no sign of meltdown
main relay 428 bypassed nothing it does have power tho
alternator cable is good also
i cant find a wiring diagram for this car anywhere even the hyanes workshop manual doesn't have it
AU Auto Mechanic: Danny, ASE Certified Technician replied 1 month ago
Relay 428 is secondary air injection, the 100 relay is the relay for the engine control module.And yes I'm aware that you won't have power to any of those fuses because all those fuses are supplied Power by the fuel pump relay and the fuel pump relay is turned on by the engine computer and the engine computer is turned on by relay number 100 in relay position 12 which is the ECM power supply relay.And Haynes manuals are junk you need to buy the Bentley manual if you're going to be working on your vehicle, family makes the repair manuals for the dealerships for all the German cars. Haynes manuals have incorrect information in them.You don't need a wiring diagram for this, the main fuse on the battery supply power to the fuse panel in the car the ignition switch is what powers up the power supply relay, the power supply relay then powers up the ECM, the ECM supplies ground to the fuel pump relay, the ECM supplies power to the fuel injectors and any sensor in the engine bay that doesn't run off 5 volts, the ECM supplies power to all the sensors that require 5 bolts and supplies a switched ground to anything that the fuel pump relay supplies power to including the fuel injectors, EVAP purge solenoid, and more.Since you already replaced the ignition switch, the ECM power supply relay is almost certainly faulty, if it's not then you'd be looking at a bad fuse box, or the wiring from the ignition switch to the fuse box is faulty which is highly unlikely.
