Why does my private plate now make my car non ULEZ compliant?

My '55 Registered Audi S4 4.2 Cabriolet was OK for ULEZ on it's original 55 Plate, but having moved it onto an S40 Plate purchased direct from DVLA it is no exempt, how do I fix this?

Other drivers who have added a private registration to their car are experiencing similar problems, as the congestion charge system relies on data from the DVLA. Until the DVLA has updated its records to reflect the change in number plate, the car will show as non-compliant.

Better than previous A4 in virtually every respect. Classy looks, plenty of kit, roomy cabin and a good crash safety rating.
