Yeh Im going to have too, I generally like to replace faulty items with new items (whether they scrub up or not) and I remember someone saying they got one for £3 off ebay. Which seems alot fairer than £45 lol. Also I cant be asked removing the bumper just to clean this plug. It doesnt bother me it just means 'Auto Function' is ineffective which I dont use anyway
Something to look out for and replace at next bumper removal.
