I've recently bought an XF wagon. Nothing special, but going over the car when I got it I noticed the front left indicator wasn't working (it was when I inspected it) I replaced the bulb and it's dull and flashing fast. I replaced the rear as well just to be sure. I have also replaced the battery terminals as the negative had a crack, earthed the lead properly to the body, cleaned up any earth I could easily reach, replaced the flasher relay and replaced the bulb housing. It's still dull and flashing fast.
I'm at a loss, any ideas?
