Got a 2010 fabia 1.4 tdi. Today while driving the interior light came on & the red door open symbol lit up on the dash, along with the door open alarm. It was a bit intermittent at first but on the way home it was on continuously
I couldn't set the alarm when i parked up as it set it off a few seconds after arming it. For now I've manually locked it by putting the key in the door lock.
In the summer I noticed that the rear passenger side door lock sounded a bit clunky & sometimes couldn't be opened using the door handle from outside & I had to operate the inside handle
My question is could this  be the problem & I need to replace the rear door lock unit, or is it the drivers door lock module that sends the signal to the alarm horn/dash light & interior light?

Would it be better to scan using vcds to pinpoint  the problem lock or would it not say?

Is there an online guide to help? I've replaced mk5 golf lock units before as they're known to be problematic but haven't done a fabia one before
