Canbus works only on the stop lights and side lights, not the indicators.
I was wondering about the flasher relay, but as 5 of the 6 indicators work as normal I thought not.
Luddite has given me a check list... which I'll let Williams deal with.
Have you investigated the blue and brown cables from loom Peter? Just to reiterate this doesn't appear to be wiring that MMC would normally have sanctioned. Very easy to just cut back what looks like insulating tape and check for any botched connection.
