EIPCW - you have *somehow* generated three very interesting answers to your totally impossible question.
The thread title says you want to REVALIDATE A PPL. That's one set of answers.
Your opening line (edited) says your PPL DUE RENEWAL (SHORTLY). That's an impossibility by definition.
Your next line suggests you have (AT LEAST! ) 12 hours total time in last two years - which in itself suggests you are talking about the class rating - and not the PPL.
Irrespective of the fact that this is very basic stuff that you should have learned by heart during your training, you are asking impossible to answer questions. It's difficult for us to help when you don't even understand your own question. Air Law via PPL Confuser was it - or regarded as "RAM/Dump" information?
What, exactly, are you trying to do? If you wish to switch to PM - and then to e-mail - I'll try and help guide you in the right direction (assuming the CAA have no objections).
