Opacity limits

Hi all,
Could anyone throw light on what the opacity limit for mot purposes are on my 2.2 cdti 163bhp exclusive. There's no limit on vin plate so I assume its 1.5 as per gov.uk but according to my local vx dealer it is now 0.5
Thanks andy

1. First used before July 2008: Non-turbo: 2.5m-1 or plate value if lower
Turbo: 3.0m-1 or plate value if lower

2. First used on or after 1 July 2008: All diesels:1.5m-1 or plate value if lower

3. First used on or after 1 January 2014: All diesels: 0.7m-1 or plate value if lower

Count yourself lucky if you don't have a value stamped on your plate, your limit will be as Item 3. My Antara has .3m stamped on it so not much to play with.

V1: CO (g/km or g/kWh) 0.163
