thanks for checking. Mine are about an inch different too. After head scratching I found my wife had set it too high, lowering it moved it away from the dash, doh! However, I could not save her seat position to memory, the memory button lights when pressed but theres no "ping" and nothing is saved. The manual only talks about saving the drivers side, but there would not be a button for memory if it didn't function, surely?
I'm wondering if this is connected to the fact I cannot memorise dipped mirror position?
