2018 Model Peugeot 508 Adblue Fault

I drive a Peugeot 508 with a 1.6-liter Bluhdi engine. The vehicle was put on the market in 2018, and it has already driven just under 70,000 kilometers. Because of Adblue, both the engine and the exhaust system in my car failed. During my investigation, I discovered that there is an ongoing problem with the system. I read some comments that said it could be done again even if it had already been done. This service does not repair the tank but rather replaces it and charges approximately one thousand euros. The fact that there was a problem with my car, which I enjoy driving so much, made me feel very downhearted.
