KO56 NJT . Apparently i was involved in an accident...but this registration number does not exist !(DVLA)

Having spoken to Adrian Flux insurance services today whilst arranging a new policy for my Scirocco, I was rather alarmed to find that, according to their data base, I had been involved in an accident with someone(unknown) on September 15th 2011 driving a vehicle (unknown) which had a registration which does not exist!.

After some Googling ,calls to DVLA and checking on the ASKMID site I have now come to the conclusion that this is some sort of mistake...but why then does it show up on my insurance claim history?

Anyone else had a similar experience?

So far have spoken to MID (Motor Insurance Database) and DVLA

Just waiting on a call from IDSL (08451652803
idsl)......hope they can throw some light on this mystery :-)

UPDATE 02/07/2015

Interesting facts. The Reg number is almost identical to that of the lorry which collided with me in April 2014 (Except that 2 of the letters in the Reg number have been reversed!)

The Entry onto my Insurance record was made (according to IDSL) by Ecclesiastical Insurance services (with whom i had a policy a few years back) . Having called them today to ascertain how a false entry was made, i am yet again awaiting an anwser.
