Hello, I bought the Touran 2009 1.9 BLS. The problem is I still have a P0401 error with exhaust gas flow too low. I replaced the EGR with a new flow meter, differential pressure sensor. DPF burned out. Ash content 44g and soot 2g. Nothing helps. Added after 2 [minutes]: I forgot to add a turbine...

Of course. Forced firing while driving. Positively completed. I used vasa.

Hello, I have the same problem, how did you solve the case?

Exhaust gas flow EXCLUDED, for nearly 600 mg, i.e.? 1 too much exhaust flows 2 flow meter is lying 3 you have hurried with the reading. Leave the engine hot at idle and take a look at the exhaust flow after 2-3 minutes.

I forgot to add a turbine like new.

Added after 4 [minutes]:

I also did the Egr adaptation.
