Hi, thanks for your quick reply! That sounds like the same problem I'm having. I recently had my Mercedes serviced, at 60009 km mileage. I don't have an error code, unfortunately I don't have an OBD2 diagnostic device. But I will definitely look for an appointment at a garage and have the glow plugs checked. I hope it won't be too expensive... Many thanks for your help! Best regards!

Hi, that sounds like a good plan! In my case, replacing the glow plugs really paid off. After that, my Mercedes ran like the first day again. With your mileage, the glow plugs should actually still last, but something can always break... So it's best to have it checked. Oh, and even if you don't have an OBD2 diagnostic device, your garage can normally read out the error code. This can sometimes also provide information about whether the glow plugs are really faulty or whether something else might be wrong. As for the cost, in my case it was 5 euros for all four glow plugs. If it's similar for you, then it should actually be feasible. I'll keep my fingers crossed that it won't be more expensive! All the best!

Hi, thank you very much for the good advice! I will visit a garage and ask them to read out the fault. I'm a little relieved that the costs were manageable for you. I hope it will be the same in my case. I will keep you informed as soon as I have an update. Your help was really great, thank you again! Best regards!

Hi, I had a similar problem with my 2010 Mercedes GLK diesel. I would describe myself as someone with a little experience in cars. My garage found that the glow plug was faulty due to wear and tear. The repair cost me 560 euros and all four glow plugs were replaced. The symptoms definitely sound like a glow plug problem, especially with regard to the long cold starts. Without the exact vehicle data, however, it will be difficult to help more precisely. Have you perhaps read out an error code? That could help. Best regards!
