ASZ smoking and smelling on cold start

Hello,

I've noticed more and more that my car emits smoke and has a bad smell during cold starts. It has 175,000 km on it.

The glow plugs, diesel filter, air filter, and battery are all new. It also starts very well, cranking for less than one second (of course, after pre-heating).

Which measurement blocks would be interesting to use during startup?

"Additionally, I feel like it's lacking power, and it seems to jerk slightly at 1800 rpm."


Best regards,
