So can I replace the Adblue myself and reset the sensor without paying the dealer $100 to do it?

You can add Adblue yourself. I've heard mixed things, Dutch VanAtlanta said that after a dealer reflash the Adblue light came on.

If it goes off and adding adblue doesn't turn it off and you waited 30 seconds after turning the car on and adding adblue, then no you can't turn the light off yourself. In other words, if it doesn't go off by itself and you don't have a VCDS tool, you can't turn it off.

It can be turned off with VAG-COM. Ross Tech has an unverified procedure that worked for me. Since it's unverified, they don't want it published to the forum until they get more verification data points.

In my case, I have a 2007 Q7 TDI, which has no Adblue tank. Due to this I had DPF problem as a result of bad fuel. I have currently dropped the DPF, but the vehicle smokes so much, which is unusual. Could it be i need to check the injector pump or nozzles. What is the best option out
