The F20 Guy 2 Report post Posted March 2, 2023 Hi Bimmer Fam i currently owned an 2014 116i F20 I've had it for 2 years done its regular servicing ODM 112Km just Got my WOF done passed with flying colours 1 week later my car started Shaking and jerking so i took it back to my mechanic to take a look at it it turns out that one of my Cylinders was Misfiring( Cylinder number 4 to be Exact) changed all the spark plugs same issue and so my Mechanic did a compression test. Cylinders 1,2,3 wer pushing over 100 PSi while Cyclinder 4 pushing over 20 PSI has anyone had this problem? or similar? if so does anyone know if this is repairable? i was informed from my Mechanic that i would need to get a new Engine But Wanna See my options first thanks Fam Quote Share this post Link to post Share on other sites

charles28 138 Report post Posted March 6, 2023 Hope things work out ok with it. I worry about mine sometimes, seems like the idles not as smooth as it should be, but no error codes and I installed new sparkplugs too. Quote Share this post Link to post Share on other sites
