Have you tried Autosol Paul? It works great on chrome on bikes and also on my chrome tips on the Macan. I don't know what the plating is on the black tips but it might respond to the Autosol treatment.

Tried it on the previous Nick, but it is a question of the matt black finish pitting / wearing off (very) prematurely as opposed to carbon build up

It's due a full proper clean so I'll have a go then, but I don't hold out much hope.

So it sounds like acid attack on the coating perhaps?

Is it worth having the tips detailed / coated once replaced. Mine were coated with Gtechniq C5.
No signs of any problems yet but I have only done 600 miles.
Will keep an eye on them.

It shouldn't happen regardless though so there must be a design flaw....

My first set of tips was detailed by JayOne (Exclusive car care) with GTechniq. No difference as they had to be replaced. this 500 mile old set has similar damage. I believe the powder coating is not fit for purpose.

Cry. I will no doubt be making a post with the same problem in the coming months. Cry

I will not bother asking the OPC to replace them unless they have a permanent fix though.
Keep us posted
