Hi. My engine managment light is illuminated. I had it diagnosed under warranty at M B of Derby they advised me that it was the connection on the Oxygen sensor, you guessed it! not covered under the used car warranty, does anyone know its location?

They are normally on the exhaust manifold. Think you'll need a slotted socket or a perfectly fitting open-ended spanner to undo it.
