what checks have been made?
Customer: replied 3 years ago.
All bulbs have been checked and diagnostic machines plugged in to get error codes that show "open circuits"
Expert:  Steve replied 3 years ago.
have bulbs been replaced?
Customer: replied 3 years ago.
Not sure. One fitter said he'd changed a bulb. The other suggested all bulbs might need to be changed but I don't think they had been. But all bulbs are currently working

the first thing to do would be to replace all turn indicator bulbs with new, proper bulbs from a dealer. it sounds foolish to buy bulbs from a dealer, but it can make a difference.

 

if the problem persists, then there has to be either some kind of resistance issue in the circuit's wiring, or a problem with the control module which controls lighting. if you drive for a long time with a short in a lighting circuit, it can actually lead to the need to replace the control unit

 

one other thing to try, which is worth a mention, is to unhook the car battery for an hour, this will reset everything and can clear out weird glitches - I would start with this, then replace bulbs, actually.
