Hi buddy, your problem sounds very familiar to me. I had something similar with my 3-year-old 2014 BMW 5 Series diesel. The same engine light and the final verdict: DPF regeneration failed. My Ad-Blue tank was also empty. But had to have more done in the garage than just that. It was a serious problem as the entire diesel particulate filter had to be replaced. The mechanic told me that a new filter was the only way to make the car healthy again. Also, don't forget to fill up the Ad-Blue tank or the messages will repeat. I hope this helps you and good luck finding a decent, trustworthy garage.

Hey, thanks for your reply! That doesn't sound too good about replacing the diesel particulate filter. Can you remember how much you paid for it? Has anything else come up since the repair? I'm really looking forward to hearing about your experiences.

Hey, you're welcome! Yes, replacing the diesel particulate filter was unfortunately a necessary evil. It cost me €1125 to repair the component. Sure, it was a lot of money, but since then my BMW has been running like clockwork again. Since the visit to the mechanic, the problem with the Ad-Blue tank has also been fixed, it was probably empty. No further problems have occurred since then. Hope this helps you!

Oh wow, 1125 €... That's a really hefty price! But at least you have peace of mind and your car is running well again. I hope I'm just as lucky with my car. Thanks for your help and the information, that's a bit reassuring! I'll take it to the mechanic and hope it's not as bad as I think.
