After a couple of hours of searching on the internet, I'm still unsure which is which. I found one site which suggests the LH relay is the fuel pump (middle socket of the three).
I'll be back at my local garage tomorrow to see what he says (he was baffled earlier today), and if that fails will try the BMW main agent to identify parts. If I get an answer, will post it back here.
If all else fails, I am tempted to just replace both of the relays; the parts are quite cheap.
Any definitive information still required ! |
