Hi Simon
Plug & wires from VW Main dealer.
Plug - 3BO 973 703 G
Pic of old plug
Repair wires - 000 979 131 EA
Should be able to release the original loom wiring from the broken connector but if that proves difficult, the repair wires will slip straight into the new connector once the purple lock tab has been slid out.
The only problem I foresee is when my wife finds out what I've done to the Nit comb. Better go to Boots later!
