Catalytic converter replacement for your BMW X4
Typical price £281 · About 2 hours
Replace a failed or stolen catalytic converter, done at a garage.
What the job involves
A failed catalytic converter causes emissions faults and MOT failure, and stolen cats leave the car extremely loud. The garage fits a type-approved replacement and checks the sensors. Working under the car means this job is done at a garage with a vehicle lift.
