I've had my car a while now but have only recently done a service on it. When poking around the engine I saw this sensor disconnected, not sure why it would be? I think it's the boost or inlet temperature sensor? Is it likely to have been unplugged because of a dash light/fault? If I just plug it back in what's the worst case scenario dash light reappearing? Also can anyone recommend any independent garages around the West Midlands, I've got the amber abs light on too any have plugged it in and have 'pressure sensor 1' fault, if the brake system will need re-bleeding to change it I might just take it to the garage.
Thanks for any help
