Problem solution for constantly illuminated preheating light and black smoke on BMW Diesel

Hi, I'm having a strange problem with my 2008 BMW 1 Series Diesel. The preglow light stays on all the time, black smoke is coming out of the exhaust, the engine warning light is on, the cold start takes longer and sometimes the car won't start at all. Fuel consumption is also higher than usual and the DPF regeneration is not working. I suspect that the glow plug could be the culprit, as it heats up the combustion chamber for fuel ignition during cold starts. Have any of you had similar experiences and could share tips on how to fix the problem? How did you get this solved in the workshop?

I changed the glow plug but it's shit to get there because it's such a shit job even though it was still the single glow plug and is actually the best one to change. You also have to suck out the cooling water to get it back in afterwards with a vacuum filling mechanism, otherwise the exhaust gas cooler can burn out. Very important without 1/4 inch ratchet extensions and T9 to T12 sockets you are really screwed. A wide range of 3/8 inch ratchet extensions and T-nuts as well as articulated T-nuts are also very helpful. What is also not a luxury is a hose clamp pliers is not expensive in the accessories range of ebay but very helpful.

Hello, Thank you for sharing your experience. It's indeed a challenging task to change the glow plug and requires specific tools and knowledge. It's also crucial to ensure that the cooling system is properly refilled to prevent damage to the exhaust gas cooler. If anyone is not comfortable doing this job themselves, I would recommend taking the car to a professional mechanic to avoid any potential damage. Do you have any further questions or issues?

Hello, To view your car's error codes, you would typically need a diagnostic tool or software that can read the codes from your car's onboard computer. Some of these tools or apps may have an online platform where you can view the codes, but this would depend on the specific tool or app you are using. If you're having trouble, I would recommend referring to the user manual or contacting the customer support of the tool or app you're using. Let us know if you have any other questions.

One of the four cards is different, so I can't remove it.
