Fuel pump relay location
Clarkj93:
Anyone know where the fuel pump relay actually is? That I can splice a kill switch into? I've been following documents online like this (can only find LHD info) https://www.google.com/amp/s/fuse-box.info/volkswagen/volkswagen-golf-v-mk5-2004-2009-fuses-and-relay which say port 5 on the top layer of the relays is for the fuel pump, well I've spliced into and it's obviously not, it will fail to turn over with it off but when it's running switching this off does nothing.
Here is what mine looks like
Or do I just splice into the cable that goes directly to the fuse for the fuel pump? Or is that a terrible idea?

I've never been able to find it mate.....or the LPFP fuse.
There is an additional bunch of relays behind the driver's side knee panel (under the steering wheel), and I think there's a few more on the passenger side. I gave up trying to find it years ago. Would have been useful for doing compression checks etc.

Balls... if you can't find it then I've got no chance. That is the one under the wheel I should have said, the top left marked with 53 I think is the starter relay I'm sure of now.

Under the rear seat above the LPFP you can unplug the power control relay/module.
There is also fuse #27 15amp off the top of my head that kills the HPFP....I always pull this one and let the car run, until it dies to depressurise the HPFP to check the follower.
ROH ECHT:
There is no relay for those from 2006 on. Could be there is no relay prior to 2006, but not 100% on that. It has the fuse and the control module on the LPFP access lid...under the rear seat.
On the 'side-dash' fuse panel...Fuse 2 is for the J538 - Fuel Pump Control Module; which again is placed into the LPFP access lid over the LPFP.
