Indicator error problem, very strange...
 

When I use the left indicator it flashes at double speed and shows "Bulb Failure" on the IPK. But on inspection all the bulbs are working just fine. But oddly, if I turn on my sidelights, the error goes away and the indicators work normally. Turn sidelights off, error returns immediately.

Any ideas how to fix this?

Look for a poor earth connection Steve.

Check the plugs that go onto the rear lights they often corrode
