I need to change the oil pressure switch on my A4 2.7 B8 which requires special tool T40175 which is an articulated 24mm socket. Due to space limitations a normal 24mm deep does not fit at all. Does anyone know where I can purchase this from in the UK? Do Audi sell them to private customers? Been searching and can only find it for sale through snapon USA (which only post to USA/Canada) for $50, there is one listed on ebay from USA for $110 (plus $20 shipping and $32 import) which makes it a crazy price.
