I need to replace the glow plug relay on my X5 E70 40d, there seems to be a few brands to choose from,are any better than others and has anyone any experience in fitting one?
Just to close this off,I changed the controller today,took around 2 hours start to finish,its probably the fiddliest job I've done on a car,you need hands like a babies and the patience of a angel,it is indeed do able without the manifold removed,just a bh of a job!
