Hi! 

I've got a 2016 2.0tdi 150bhp crlb Skoda superb, I am having issues with the car lacking power and throwing out smoke, the car was first diagnosed with a blocked dpf and egr, we have now gutted the dpf as it internally exploded and blocked off the egr. Was just to expensive to replace the dpf unfortunately! I've also put a new turbo on as it damaged the internals of that. I have changed the boost pressure sensor/n75, map sensor. Maf. And now the car is better, but still has no power in 1st and 2nd gear, then probably about half power from 3rd onwards. The injectors appear to be flowing fine as I've had them tested, we have done a smoke test and there are no leaks, the car has been coded to remove the dpf and egr aswell.

I honestly don't know what else I can do and I think I just need a specialist to have a look now.

Thanks so much,

Phil

Could anyone recommend a specialist perhaps please? I'm based in South Wales, but at this point I will take it anywhere!

If the DPF exploded , I assume downstream was also cleaned ?

Yeah it's all been cleaned out I believe, I do think the only thing that hasn't been off is the charge cooler though actually

Those symptoms point to maybe a blockage somewhere. Wonder if the cat is ok or if some of the dpf ended up in exhaust somewhere.

Either the SCR is blocked or you have issues elsewhere. Was the EGR/DPF mapped out?
