Checked and cleaned earths etc. due to it not happening all the time.
One of the threads about the amigos talked about the yellow green wire in the ABS harness being loose. They took the connector out of the block with a fine screwdriver to push down the retainer piece on the connector, retensioned the retainer, pushed it back in and the 3 amigoes didn't reoccur.
I didn't go to this length, just pushed the yellow green wire firmly back into the connector block and onto the terminal it was meant to connect to. So far, (touch wood), it's been over a year without them reappearing. Interesting, if you do an Option B mod, it also bypasses the connector block.....
BTW: I don't want to resurrect the whole 3 amigoes discussion, just add to this thread.
