Hello, The alarm on my 2004 Vaneo (recently purchased second hand) does not work. I have checked that the 10 Amp fuse is in place and in good condition but have searched in vain for the relay box in the engine compartment to check the relay K46. There is no such relay box in the position shown. I would appreciate any pointers to the location of said relay box.
Hi, i have a similar issue as Mark Lyons, 2005 Vaneo W414, 1.7CDI manual transmission, I too have the issue with the alarm and horn does not work. I have checked that the fuses but have searched in vain for the relay box in the engine compartment to check the relays K39 & K46. There is no such relay box that I can see. Any help / info would be greatly appreciated.
