What a bloody pain this is...
Working on the car most of Tuesday afternoon then went to finish up, locked her up and 5mins later the indicators start flashing. Unlocked/relocked now the siren starts wailing.
After about 15mins frigging around finally stopped after opening and closing all doors and starting stopping the engine.
Wednesday morning the neighbor across the road knocks on my door, indicators flashing again no siren. Spent nearly an hour frigging around trying to get it to stop. Finally decided to try disconnecting the battery for half an hour. Also sprayed a bit of inox in the bonnet sensor as it wasn't moving very freely. Since then it hasn't done it again (that I've noticed) so fingers crossed maybe it was the bonnet sensor.
But now since disconnecting the battery I had the engine check light on constantly that hasn't been on before!! Resetting the codes doesn't turn it off. So now I have to work through the codes again and try and figure out what's wrong now....
Think I should have stuck with a WJ
