Quick Question please, I have read loads on this subject re the relays solder causing the “engine management light” to come on intermittently. Upon checking mine this morning the solder joints were all ok but the relay contacts were badly burnt. I have filed them for now and everything seems to be working fine, as per the below photos, but my question is can you just get one of these relays and re solder it on the board or do you have to get the full block. If so what’s the part number and where can I get one posted to Australia. Thanks in advance.
