DS – Exhaust gas cleaning smoke and stench

Hello everybody, I have a question for the diesel drivers. The exhaust gas cleaning on my DS MY2017, 180 hp diesel has become a massive nuisance for me. After now 56,000 km in 1.5 years the interval has become ever shorter, partly only 60 km between the cycles. But the worst is the smoke and stench! When the cleaning starts again in the city traffic and I have to stop because of traffic, I now have to turn off the ventilation completely. If the vehicle is then standing, thick clouds of smoke come from the engine compartment and push at the sides and at the cooler out of the engine compartment, I have already been addressed: “Your car burns. Everyone who drives with me immediately notices the smell and is appalled. I have not experienced anything like this at VW, Mercedes, or BMW before. Twice already with the friendly about it, they say that is normal and I should just drive and not stand. Great tip, because I can’t control when the cleaning starts. And strictly according to Murphy’s law, the cleaning NEVER runs when I’m near the workshop to demonstrate it… What’s this like with you? Similar experiences? I really like driving the vehicle but by now I’m longing for the end of the leasing period 🙁
