Flasher relay information You may find useful ( Courtesy of R.Ambrose )
I've marked the relay IND.
Note the relay marked C\L is the central locking relay.
If you haven't made it out yet, it you'll need to remove the plastic facia to the front speaker. Below and to the right of the steering wheel.
My relay packed up and I've replaced it with one suitable for LED's. However the rate doesn't change if you loose a bulb so I have to check now and again.
To remove the relay, the original has clips top and bottom which need to be squeezed.
