hello, please help me.  in January I bought a Skoda superb 2 2012 140KM cffb original mileage 241 thousand kilometers.  as the temperature outside began to rise I noticed that the tips of my exhalation were turning black.  but when driving behind me I don't see any smoke even under load.  the soft engine I had was 9978, the one after the diesel Gate scandal.  DPF regenerated for me every 500-600 km.  at a standstill, when I added gas from the exhaust, there was not much black smoke but not really much.  Two weeks ago, I gave the car to the tuner to increase the engine power and return to the software from before the diesel Gate scandal because the car at low revs was accelerating very slowly.  the tuner restored the engine map to 7128 as this was the only one available for my ecu.  raised the engine power and basically everything works as it should, but unfortunately since then DPF burns out after about 300km with about 15g of soot.  the car still emits a lot of smoke when I add gas while stationary.  basically, as on the 9978 software, I have a new egr in my car.  I have +/- 0.3mg injector corrections and the DPF filter ash is 0.16l.  idle pressure difference is 3hpa.  I am asking you for help.  Is it possible that the car on the 7128 software from before the Gate diesel scandal would regenerate the DPF after 300 km and on the 9978 software after 500-600 km.  is there anyone who has soft 7128 and could help?

Sounds like a smoky remap. Go back to your tuner and ask them to restore your car to the standard 7128 map to see if it improves things first. If it solves the problem then you need to talk to your tuner about a different map that will produce less smoke/soot.

I found a Skoda owner with 7129 engine soft, which is almost the same. he has the serial power of the car. and also with him, the DPF burns out every 300km, i.e. with 15g of soot, it starts to burn out.it seems that this is the fault of the software, not the tuner. since in another person on the 7129 software on serial parameters it also burns out so often. unfortunately there are only 2 engine software 9978 and 7128 for my ecu. what to do in this case? ask the tuner to restore the 9978 engine software again and raise the power on it? because i heard bad reviews about 9978. is that true?

this is how the dpf is filled with soot at the moment.
