I've just picked up a cheap 51 plate A3 130tdi.
The car came with 2x keys with a light button, but no radio function. I believe anything after 1997/1998 should have a CL pump that supports RCL, so I'd guess that a previous owner had lost or broke their flip key, as one wasn't supplied.
Could someone confirm that ALL 2001+ models should have RCL.
Secondly, I've searched on this forum and found a file that shows the softcoding options for the central locking, however the link is dead. Does anybody have the below file, that they could send me? Just incase I need to turn this funciton on, in the event it wasn't dealer-activated
