Black smoke on acceleration and fault code P0087

[youngy93]

Hello, being having abit of a nightmare with 1.6hdi 90, had dpf delete about 2500 miles ago, about 3 month ago the car started smoking heavily under load, eventually came to find that turbo was on its way out with play in turbo and failed oil seal.
Replaced turbo with new, sorted out banjo bolts etc.
Car still smokes on acceleration worse at low revs, higher they get the cleaner it is.
Doing a 2nd gear pull felt a stutter then limp mode with fault code P0087?

Next on the list is to replace fuel filter

Also had 2 intermittent fault codes of;

P1403 & P1404

Thank you!

Did you get it mapped at the same time? If yes, then it must be a bad map if it's not ensuring a clean burn the whole time. Also if yes, how much power with decat and remap out of interest?

But also, the DPF catches the black stuff. You removed it, so black stuff comes out now. Good luck when MOT comes round too, hope you have a "friendly" tester.

If you have removed the DPF, there is nothing to catch the soot before it comes out of your exhaust. It's probs only just started happening as the build up of the black soot is now sat in your exhaust pipes rather than in the DPF, so when you accelerate harder, its more likely to blow it all out.

Any kind of smoke emitted from exhausts is now (from 20th May) an MOT fail and "evidence of any tampering with the DPF" is now classed as a MAJOR fail.

As BenS says, I hope you know a friendly MOT chap, otherwise it ain't gonna pass now.

I had it mapped a few month prior to the smoke issue arising so in 2 minds whether its that, map was my thinking until I found the turbo was goosed, good thing with the dpf cannisters on these is they don't require any cutting welding etc so no visual damage. Just the smoking which is the issue now, going to change the fuel filter tomorrow and hopefully that should help with the low fuel rail pressure but in the back of my mind I'm thinking its most likely an injector. When a car is mapped reputable theres minimal smoke, taken it for a "custom" flash but aimed at power so going to see if it can be changed to eco and see if that fixes it. Still digging around for a possible boost leak aswell

Best of luck!
