valet

Just wondering if there's a way that I can get round having to put my cats back on for MOT really, as I really can't be fooked with them! I've got an APR switchable map, one of which is valet mode. I'm a total newbie to engine management and have no idea at all whether this is a stupid question...

Hi guys.... .....anybody have any recommendations where i can get a full valet (interior and exterior including engine bay?)?? Not sure whether to use a mobile one or take it to a proper valet workshop? I'm in the midlands area so any help would be greatly received? Thanks :confused:

Can anyone help was just reading a thread somewhere on here and someone mentioned whilst on holiday he left his cupra in valet mode. Can some one tell me in more detail if a cupra has this function and what it actuall does cheers.
