Hi, my good lady had a problem with her Mk1 Octavia estate- when she went to fill up with diesel, the flap would not open. I replaced the solenoid/opener having checked for current at the plug, but it still wouldn't activate. On testing with a voltmeter, I found I was only getting 7 or 8 volts at the solenoid. I tried the switch on the dash and that also reads 7 volts supply, although the voltage across the fuse is 12V. I was wondering whether there is anything else I should look at between the fuse and switch. Any advice would be most gratefully received. Thanks! Mark

The switch sends a ground to the flap motor the 12v supply should be on pin 2 of the flap motor at all times

Thanks for that, I've just got round to having a look and am getting 12V between the solenoid and earth but having replaced the switch and solenoid, still no action .I will keep playing with it, thanks again.

The #10 in the diagram coming from the fuse goes to the main central locking unit and A23 feeds the two bulbs in the boot area
