Mine just twist off.... Are they the rubbery plastic ones, or have you got maybe aftermarket ones? Some need a special key

 

I assume they are originall ones ? On when i recently bought the vehicle,,,, they are metal ? maybe alloy ?

 

Ok they could be aftermarket and need a special tool. I'm no expert but I'm sure some one will be along to correct or confirm in a sec...but I've never seen standard alloy dust caps myself. Some aftermarket ones are designed to spin so pesky kiddies can't steal them for their bikes :lol:

Have you tried pushing down and twisting, like on a medicine bottle?

 

Lefty Loosie, Righty Tighty:lol:

 

Sounds like you got anti theft ones.

If you haven't got the little key ring tool thingy you can twist them off with a pliers

 

so only anti theft if the scrote does not come equiped?? :cheese::cheese:

 

'Not quite anti theft dustcaps' :lol:

 

more a sort of Anti-bored-little-scrote-with-sod-all-tools-and-even-less-initiative-for-opportunist-theft dustcaps then!! :cheese:

 

:lol:

 

Some toe rag stole two of mine off the 156 last week, the car was on the drive as well, reverted back to the usual black plastic ones till I decide the way forward.
My Spider is always garaged so no worries there!
