Clicking / buzzing sound in fuel cap cover when locking car

[P Adams]

Hi all

After sorting my wife’s B7 and getting on with life I thought I’d have a few months of ‘normal’ motoring!

Well my 2015 B8 GT 2.0l TDi saloon has started acting up around the fuel cap cover. When I go to lock the car it makes a clicking / whirring / buzzing noise for a second and then locks the cover. When I go to unlock the fuel cover with the normal key fob, it sometimes stays locked and sometimes opens after a few lock and unlock clicks. The clicking noise still sounds off though.

I sprayed some silicone spray into the small locking pin area and that seems to have helped allow the unlocking of the fuel cover, but the clicking noise still remains. I can feel a slightly expensive diagnostic / replacement coming from my friendly VW pals! Any thoughts anyone?

Much appreciated

Paul
