Well done locating those splices! On the face of it they look like the regular barrel crimps.
Perhaps worth doing a light pull test on those UR and SR wires just to check the crimping integrity. That would at least rule out a poor mechanical crimp but unfortunately would not necessarily rule out high resistance from any corrosion.
Have you considered re crimping through the heat shrink? Perhaps give them another squeeze (in the orig direction) with a crimp tool. Then just sit back and see if the prob goes away.
PS- Where were they located, other GDI owners may be interested?
Hi,
I had realised, as Richard points out, that the connector and splices must be close together with the Relays shown in the diagram. So in the Fuse Box, just moved the BCU out of the way (just Velcro in) and removed a bit of tape.
Good idea re pulling on the wires and re-crimping, can't hurt to try.
Thanks
