Front door wiring loom replacement and locks.
On the 2008 125k miles A3 I've just bought for my daughter it has the not uncommon (I've learned from reading past threads) front door locks which don't open with the plip. Also the wiring has several wires in the drivers door shut area with broken insulatIion and a couple where the copper is just starting to break.... plus the passenger side has just two with insulation cracked but copper inside still unbroken.
I'm taking the door cards off today to see if the fault is the same as this guy
Annoyingly the new loom didn't make the lock work so I guessed my lock repair hadn't worked well and ordered a 2011 lock from a breakers... but that displayed exactly the same faults and codes. So I wasted ages stripping the two locks I now had... cleaning up the motor commutators... greasing the moving parts and even re-assembling them in various combinations of parts from the two locks mixed together... but still no luck.
