Hello everyone. Just 15 days ago, I bought a 2015 Peugeot 308 1.6 BlueHDi 120 Allure from Izmir. I drove to the Anatolian side of Istanbul with it, no problem. I drove in the city for 2-3 days and it gave me a warning to add AdBlue, 2400 km. I bought AdBlue from Shell and added it (it took 7.5 liters of fuel). Is this true that I have to wait 10 minutes without doing anything? (I didn't)? After adding it, I get the same warning every time I turn the ignition (The engine malfunction light isn't on, it just says to fill up). I had the expert do a full detailed inspection at Izmit Auto Expertise, and no such problem was found. Today, I took it to the authorized service for diagnosis. They asked for a 2000TL diagnosis fee. A report will be prepared tomorrow and I will share it with you. I stuck the car in S mode, the engine malfunction light came on twice, and after 3-4 stops and starts, the malfunction light went off. Can AdBlue do this? If there is a problem with the past, can I request a report from the dealer and an expert? Does the vehicle have a DPF filter, and if so, do I need to add DPF fluid?
