The car manufacturer is cutting the amount of employees required at its Mini plant just off the Oxford Ring Road in Cowley.
But it is not yet known whether similar redundancies will be carried out at the Bridge End Road factory in Stratton.
The two facilities form part of a Mini production triangle that connects with Plant Harms Hall in North Warwickshire.
The Adver’s sister paper, The Oxford Mail, reported that BMW is moving to a different shift pattern as it phases out old vehicle models, and is reducing the amount of temporary staff required in the city.
A spokesman told that newspaper: “We are in the process of phasing out our current models and building up to new ones next year, which is normal in the automotive business.
“This means that we will be producing fewer cars than usual for a period and so we need to move to a different shift pattern.
“As a result, some of our temporary staff have been stood down.
“We understand that this has an impact on part of our team employed by Staffline and we are doing everything possible to retain as many as possible within the business.”
The Adver approached BMW for comment as to whether this decision would affect staff in Swindon but has not yet received a response.
