Starting problem and black smoke in Smart fortwo

Hello, I have a 2002 Smart fortwo 450 diesel with 360,000 km and I have the following problems: in winter the car won't start, even though the starter is working properly, and the battery is running out from the many attempts to start it. In the summer, the car starts immediately, but it emits a lot of black smoke from the exhaust during acceleration, as if it is clogging up. The garage is trying to locate the problem, but to no avail so far. What could be the problem? Thank you.

For the winter starting issue, check the glow plugs and their relay, as they are crucial for starting a diesel engine in cold weather. For the black smoke, inspect the air filter and clean or replace it if necessary, as a clogged air filter can cause excessive smoke. Let me know if these checks help or if you have any further questions.
