Hi,
Behind the bulk head cover on the passenger side (Behind coolant tank) of my M3 I came accross 3 relays.
Does anyone know what the 3 relays are used for?
Cheers

the large square black relay nearest the passenger wing is the evaporative purge realy. (mine doesn't have htis as it's a very early one)
One of the others is the main power relay, which does all the igntion live in the fuse box etc.

Can't remember the other one.

Have a search about on s14.net, you should find what you need there.

mines exactly the same,

but My fuel filter is located where the evaporative purge stuff (charcoal canister etc) normally sits. So I presume it's not meant to have it!

IF the car is non cat then it doesnt have the purge valve.
