Hello! The car is an Opel Zafira Tourer, 2017. The car had a multimedia based on the AC8257 processor with a Canbus module installed on it and everything worked as it should for months. I replaced the multimedia with DUDU7 and the engine light came on and the car recorded some errors. I clear them, but after about 15 seconds of engine operation they appear again. When I turn off the multimedia on DUDU7 the problem is gone. What should I do to solve the problem?
