Default Smoking exhaust

I had the management light come and and O2 sensor was the problem . It was reset and following the advice given here waited it went about 3weeks came on so booked it in for change also had the timing belt changed at the same time all done today .Prior to this the car was running fine .Drove home about 15 miles car seemed fine and as I backed up the drive saw black smoke at the back .Question is there anything the garage may not have done properly to cause this . This beast has and is costing me a fortune and not being too mechanicalwill have to take the garages word for what the new prob is which no doubt Wont be theirs
1999 V70 AWD automatic 60 K

Thanks for any advice

Hi I dont know if tey reset it . I took it back thismorning it started and ran ok for the first 5 miles then the management light came on and it was a bit lumpy and erratic idle . Still had black smoke .My concern is the garage posibly saying its anew fault though the car was running ok prior to the change .

Update on the garage response they have refitted the original sensor and the car is running fine (they say) now waiting for another sensor as the replacement is deemed to be faulty?
