Unusual Odor and Smoke from Mini Cooper's Engine - Any Thoughts?

Strong exhaust smell

I've been noticing a strange burning smell from my Mini Cooper after driving. When I open the bonnet, a small amount of smoke is visible from the back of the engine where the EGR and DPF are located. Additionally, the main cooling fan is constantly on, even when the air temperature is quite low (around 2 degrees). Has anyone experienced similar issues or have any insights on what might be causing this?

Smoke from back of engine Engine I hot and fan running but out side temperature is low (winter)

It sounds like your car might be overheating, which could be due to a variety of issues such as a coolant leak, a faulty thermostat, or a problem with the water pump. Start by checking the coolant level in your car. If it's low, you might have a leak. If the coolant level is fine, the thermostat or water pump might be the issue. In any case, overheating can cause serious damage to your engine, so I would recommend getting your car checked by a professional mechanic as soon as possible. Please keep us updated on your progress. Do you have any other questions?

It's possible that the EGR cooler could be the issue. If the EGR cooler is leaking or blocked, it could cause overheating and a burning smell. However, replacing the thermostat is a good first step. If the problem persists after replacing the thermostat, I would suggest having the EGR cooler inspected. Please keep us updated on your progress. Do you have any other questions?
