2002 1.9tdi Avant... Due to the common water ingress on driver's (uk) side. I've tried everywhere to get a 'pointer' towards what's damaged, causing brake lights on permanently, usually headlights, eccentric indicators, wipers etc. I have to disconnect battery to switch off. I've replaced the brake light switch to no avail.
I was suspicious of the CCCM but that side seems dry and the water was getting in on the other side behind the fuse board close to all that wiring and I'm guessing, the CECM?
Surely pleeese someone knows which module controls the symptoms I'm getting. Would be much appreciated.
