I’m having an issue with my 2019 Marco Polo (V220d) and wondered if anyone has experienced something similar. I’m getting quite noticeable chugging, particularly at idle, along with a warning that the engine oil is too high.
My Mercedes garage suspected the fuel pump, so I’ve had that replaced but the problem is still there (albeit intermittently). Unfortunately, that’s knocked my confidence in the garage so I’m keen to see if anyone has experienced something similar. Or any ideas on the root cause or how to fix it? I'm keen to avoid the expense of going into the main dealer to diagnose and fix.
