Is there any online engine number decode for YB cossie lumps that tells you year of manufacture???

The way my car is registered, my emissions on MOT are based on engine age. Ive got engine build reciepts going back to early 1992 and they have been used in the past to satisfy the MOT man to do the non cat emissions test.

With things tightening up with IVA etc, i want to be able to prove it with the engine number confirming it was built pre 31st july 1992.

So has anyone got tables that will enable me to decode YB engine number???

Also does anyone have a decode for DVLA issued VIN numbers???
