AGM84

I know - it is completely butchered, I had a lot done to it a year ago and it does run really well bar the smoke. Someone tried to mod it and just made a complete balls up of it! I don’t want to spend more than a few £100 on it, otherwise it’s not worth the risk and will just sell without an MOT. Just wondering if an air filter change and a dose of RedEx or BG244 would clear up the smoke enough to get through the MOT. I don’t foresee a long life ahead for it but as it is currently very driveable it would be nice to get a few more miles out of it...

Yes it's a TDI. from the MOT I can only see one emissions measurement. the absorption coefficient. Test limit was 0.6 , it averaged 2.8 so way out.

Apparently they can't tell it doesn't have a DPF unless they pull it apart?

Its at 122k. It didn't come with a service record (I know, I know, but it was bought in an emergency). I had £4k worth of work done on it shortly after I got it, it drives really nicely but just smokes.

I bought this car in a rush last year, it had a long MOT and ran well but after buying it, turns out someone had completely butchered it (sorry, 'tuned' it)...£1000s later, and a year later it's run perfectly fine apart from smoking on start and acceleration (was an advisory on last MOT), but just failed its MOT on emissions. It's quite a way over, 2.82 when it should be 0.6. Just wondering if anyone has any ideas on this - I want to cut my losses and sell, and get a car on PCP instead (which on reflection I should have done in the first place). But I have quite a bit of money in this car (inc. owing my dad..!), and imagine if I sell without an MOT I'm not going to get much. Apparently it's had the DPF removed. It hasn't been serviced, the garage suggested a new air filter and a clean up might help. One of the advisories today was oil leak, but not excessive. I'm happy to spend a few £100 if it means I can get it through the MOT. Any tips? Would a new air filter, clean up, oil change, fuel treatment etc be able to lower the emissions enough? Otherwise it runs and drives beautifully, does a couple hundred motorway miles a week and great fuel economy. Thanks!
