I've had a good google around this but I think I need some knowledgeable help and hoping someone on here may be able to help.

My old Golf TDI (about 2004 I think, 115k miles) has just failed it's MOT based on new emissions regulations. (diesel smoke level I believe) 

As I understand it the government level for this car would be 3.0. if no 'plate' can be found. Apparently my 'plate' level is 0.7 which is what needs to be used. My car tests at 1.4

So a 'random' (given that it is linked to when the car was new etc.) level, that is probably very low in order to look good (it is a VW and this is emissions remember) is going to force me to scrap a perfectly functional car, even when it comes well within 'standardised' government levels.

Does this make sense (i.e. have I understood it correctly) and is there anything I can do about it?

Thanks in advance.

A good blast up and down the motorway with a good fule additive in the tank. My old van used to smoke because I pottered about in it but a good gulp of whatever injected cleaner my mates garage recommended and thrashing the arse of it for a bit sorted it out every time. 

Ah, thanks, I do mainly do shortish journeys. 

Just as an idea do you think an hour will do the trick, or a long 4hr+ needed?

Thank you!

With my old diesels I also did as above, week before the MOT I would fill tank and put in additive to clean injectors etc. and just before the test hammer the car at full revs - typically drop it into 3gear and full revs up a long straight hill. It is a little scary but you will not believe the s*** that it blows out.

Worth a go.

Again, thank you, I will also give that a shot!

In my case about 1 hour. I would jump on the M62 at Leeds and go to the M61 and back again. Some good hills on there and no speed cameras. 

+1 for a good thrash pre-test.

Always make sure the car is properly warm before taking to the test

Does your car have a DPF, or has it never had one fitted even from the factory?

Will have a look, thanks.

Scotty Kilmer has the answer. It helps if you can do a basic oil and filter service:  youtube.com/watch?v=5I71er1vxZQ&

This is the stuff I used when my old car was not running well, double dose the first time and as above a right good thrashing.

Change the oil, oil filter and air filter in addition to a fuel additive and a thrash. Good luck.

It passed. Just. Thank you for the all the help everyone.

Well done, sell before next MOT??????

Yeah, that is something to be thought about. But for now it's okay, and it's emissions are very low so I'm not gassing everyone, it's only because the plate number is so low that there was a problem.
