Im not so sure about that.
Note 1 states:
This document tells you that your vehicle has not been shown to meet the minimum legal requirements for the reasons detailed in section A. If you intend to use your vehicle on the road you should have it repaired without delay and have it retested BEFORE THE EXISTING TEST VALIDITY EXPIRES.
This to me suggests that your old mot is still valid until its expiry date (unless the existing test validity is the 10 day period being the maximum time between a test & retest.
Note 2 appears to apply if the old mot has expired.
Can ayone verify?
