Passat (B5) :: 2002 GLX Stalled - Small Click Inside Relay Panel But No Crank

B5.5. Here is what happened: Was driving as usual, running low on gas. Cluster was showing zero miles left for last 10 miles. I successfully made it to the gas station. Trying to open lid - maybe on third press it popped. I thought I'm just imagining things. Drove home another 5 miles. Trying to open trunk - same as gas lid, eventually opened. I turn engine off. No dome light. None of the dome lights working. Everything else appeared still has power. Trying to open trunk again - it's dead. Trying to start the car - does not start. Trying to go home and lock with remote - not working. Lock manually and went home.

Next morning went to check fuses - all OK. Everything still not working just the way I left it. When ignition key turned - cluster comes up. When starter should crank I can hear small click inside relay panel and lighter power turned off momentarily as usual, but no crank. No messages on cluster. Dome lights, door locks by remote and starter/engine don't work. Gas lid and trunk don't work even from driver's door. If I press power lock on driver's door it will lock and immediately unlock all doors.

I did check power on fuses. Three engine related fuses don't have 12V on them. The fuses are 28, 29 and 34, or second and third up from bottom left and fourth up in second column from bottom left. Fuses itself are good.

Here I Got my first suspect: power for all 3 fuses above coming from same relay. I thought if I jump these fuses to live 12 Volts I might be able to start engine. I did jump one fuse at the time. I've heard fuel pump came up but nothing else happened. I understand that it can also be Motronic control for this relay. I pull my OBD reader, but found no codes or freeze frames. I don't have WAG reader.

But Motronic should not affect doors and dome lights (I think so but not sure), unless CAN bus shorted or something. Lights and doors can be related to Central Control and Convenience module, which supposed to be under driver seat. I had rear driver side carped wet few times when I just bought the car, but not lately, not in 6 months. I still think water damage can occur much later after exposure.

So here are mu suspects: Engine power relay, Motronic or Convenience module. It might be something else.
