What to do next
If you own a Mercedes-Benz B-Class, check its registration on GOV.UK and ask a Mercedes-Benz dealer whether any recall work is outstanding. If you are buying one, ask the seller for proof the work was done, and run a Motoring Insider history check for finance, write-offs and the MOT history.
