hi all, i just got my 1st bmw!

its a 325i in blue. no pics yet as got a few things on the car to sort

in this case the previous owner told me he replaced the brake pads and the light is on and needs resetting? is this right?
airbag light is on, had a look under passenger seat and the occupancy sensor was just hanging, so plugged it back to seat.

yesterday coolant light came on, added coolant only to see some coming out the expansion tank at the bottom it was not doing that the other day

other than these little faults she drives lovely and coming from a few scoobies and previous car a clio 172 the pot holed roads are not for me any more !!!!
