It all started about 6 months ago while on a drive with the Oz Audi Melbourne. I get this annoying click when I press the accelerator or take my foot of it. Sometimes its louder than other times. You can even sometimes feel the point where it makes the click. I thought it might be stones under the base so I undid the screw that holds the accelerator and vaccumed between the carbet and the base but no luck. Can I use a silicon spray lube on the joints? will it affect the electricals or it should be ok? otherwise im very close to getting a new one.
