Focus Diesel Jerking and Stalling

Greetings, fellow Focus owner. While I do not own a 2018 model, your symptoms sound familiar to an intake manifold issue I had. Were there any mentions of manifold pressure irregularities or a vacuum leak in the error codes? Any chance of a gasket leak, perhaps leading to engine misfires?

Thanks for the quick reply! I'll check the exact error codes again, but I think I remember something about manifold pressure being mentioned. How did you eventually resolve your issue? Was it definitely the intake manifold?

Yes, after further investigation, it was confirmed to be a leaking intake manifold due to scorching. Considering the stored errors and the correlation with the symptoms you described, I suggest consulting with a trusted workshop. It's better to have it professionally diagnosed. I ended up paying around 1180€ for parts and labor but it resolved the problem completely.

Thanks a lot for your help and the advice. I appreciate the information! I'll take it to the workshop and report back.
