Just booked my c class into Inchcape for a service opted for the express service, I was then contacted and told I needed a safety software update as well which would be free but could take up to 4 hours. I then asked what the update was and was told NOx emissions I said I did not think this was a safety recall and would not have time for this at the moment which is why I opted for the express service, was then told they could not remove this from the service sheet and if I did not have it done my car could go into limp mode. Has anybody else had this problem car is 2 years old.
