Problem solutions for smoke from the exhaust and loss of power in a BMW 1 Series Diesel

Hey, had a similar problem with my BMW 3 series, model year 2006. As I said, I'm not a mechanic, but I was told it was damage in the wiring harness that caused the problem. I had it repaired at the garage and it cost me about 120 euros. But as I said, it would be best to consult a professional. What kind of engine do you have in your BMW 1 Series? Have you ever had the fault memory read out? I would be pleased to get more information so that I can better assess what could be wrong. Hope this helps a little.

Hey, thanks for the tip! My 1 Series has a 2.0 liter diesel engine. I haven't had the fault memory read out, but that seems like a good idea. I'll ask my mechanic about it. I haven't really noticed any other symptoms except that it sometimes jerks a bit when accelerating, but I thought that was normal. Could it be that a spark plug problem is also causing this? Thanks again!

Hey, it's definitely not spark plugs; this doesn't matter for diesel vehicles as they don't have spark plugs. Instead, diesel vehicles have glow plugs, which ensure that the diesel ignites in the cylinder. It is definitely worth having the fault memory read out. This can definitely help your mechanic and narrow down the exact fault. Hope this helps you! All the best for the repair!

Wow, thank you very much for this detailed answer! That explains a lot. I am confident that I can now talk to my mechanic better and hopefully the problem will be solved soon. I'm looking forward to driving again without any worries!

Hello. BMW Serie 1 Diesel Type: 187UD71AJ Black smoke, then the engine stops on the road and no longer starts.

(Translated from French)

Black smoke from the exhaust usually indicates a rich fuel condition, meaning too much fuel is being burned. This could be due to a variety of reasons such as a faulty fuel injector, a clogged air filter, or a malfunctioning sensor. Since your engine is not starting, it could be a more serious issue. It's important to have your vehicle inspected by a professional mechanic as soon as possible, as this is a safety concern.

Hey good afternoon, so I just got a code that says air mass system, and I was just curious as to what yall might think in causing this issue?

The code indicating an issue with the air mass system typically points to a problem with the Mass Airflow Sensor (MAF). This sensor measures the amount of air entering the engine and is crucial for your engine to run properly. A faulty MAF can cause a range of issues, including poor fuel economy, stalling, and difficulty starting. A simple first step is to check if the sensor is dirty or obstructed, as this can sometimes cause the issue. If cleaning doesn't help, it may need to be replaced. Please update us on your progress.

Given the extensive work you've already done and the symptoms you're describing, it sounds like you might be dealing with a fuel delivery issue. This could be due to a faulty fuel pump, clogged fuel filter, or a problem with the fuel injectors. However, white smoke from the exhaust can also indicate a coolant leak, which could mean a head gasket failure. This is a serious issue and should be checked by a professional mechanic immediately.
