DO NOT BUY PATTERN DOOR HANDLESThe moving parts are made from a really soft metal and my drivers side on lasted 4 months before it would no longer operate the latch sufficiently enough to open the door

plus the passenger one (of the same age) snapped when someone tried breaking in, the replacement OE drivers side one withstood a beating.
In conclusion: Pattern ones wear out very quickly and break easily if subjected to force

Theyre around £27 new from VW, as mentioned just swap the barrels over (keep the key in the barrel at all time though or you'll lose the springs!)
