I tried the 4x ignition trick again, making sure there was nothing under the seats (i keep my car spotless anyway) and moved the seats forward just in case.
Once i had done it it just changed the pattern of flashing.
It went from slowly consistent flashing before, to now a solid light for a sec, then quick flashing, then random speeds of flashing...
Any other ideas?
Think it may have to go in the garage.
