Nice. I will watch for later updates on this car. One thing I am most interested in is how long before the dpf has to be replaced. With semis they have a limit with miles (iirc MB has the ecm set a code around 400k that the dpf NEEDS to be pulled and cleaned) The soot built up in the dpf will leave behind an ash that after so long plugs it up, as I said tho, on semis we can pull them off and clean them out provided they pass a couple tests. But with automotive they don't make the dpf serviceable, so when the limit is reached you remove it and install a new one. Also, you stated about fuel being injected to get the dpf up to temp, mostly they need exhaust temps to reach a certain level before the fuel will start to be injected.
