Hello 310K KMs.. (195K Miles for US friends). Car shudders very noticeably/audibly when below 20KM/h on low battery, on 2 bars. Once battery charge is above 2 bars, the shudders reduce in intensity significantly but it is still there as long as ICE is running. I can tell because as soon as I drop into using electric engine only, car is fairly quiet. EGR was cleaned out as per previous owner. The low battery shudder was always there since I bought it earlier this year. The shudder at all times is recent. What are some /likely possibilities here?
Is the shudder worse when engine is cold? Are you having to add coolant regularly? Any check engine lights (error codes) or other symptoms?
