Welcome to 1ADDICTS!
As
zx10guy said, there is no owners manual specific for a PPK equipped 135i, but
here is a link to the US owners manual. Noticed you're in South Africa and don't know how different the cars are there from the US version.
Also, which version of PPK do you have? PPK1 is software only and PPK2 is the same software plus some extra cooling hardware.
If you have any questions about PPK or your car in general, ask here and hopefully someone can answer your questions or steer you in the right direction.
