Every year VOSA announces that there is new data available for Petrol MOT Emissions Testers. All Petrol MOT Stations are required to use this data and program from 1st August. Where the data is available on disk VOSA expects it to be installed by the end of August at the latest.

For the last Eleven years, most Crypton MOT Emission Analysers have been fitted with CD-ROM drives. If all your Crypton emissions machines have a CD-ROM drive, please select the CD-ROM option.

Please ensure that your CD-ROM drive works and that you order the right update as there will be a £50+VAT surcharge for sending out a set of floppy disks to customers who initially purchases the CD-ROM option.
