Anyone any info on what might be causing this notification? So far it has had the rear left seatbelt pretensioner replaced a few weeks ago and then a new rear left seatbelt yesterday. Today the alert reappeared. Yesterday's service (new seatbelt) was from a mobile ranger, so no inconvenience really, but the two previous services (diagnosis and then new pretensioner) have been visits to a service centre. Beginning to get slightly fed up, though it doesn't affect the car and I almost never have rear seat passengers, so no safety concerns.
