I drove on the highway with my Mini Cooper S R56 and did it one or the other time properly. Then at once the engine control light went on, only flashed at first and then it lit permanently. Engine ran from then on totally restless but still drove home, there was totally jerking at the gas. It felt as if the little one was only running on 3 pötten. At home once oil and everything checked, then started again and at once the control light was but I didn’t dare to turn around again. Then immediately read out fault memory, zack 4 errors in the engine control unit among others super knocking and fuel shutdown due to super knocking. Now I don’t know what it could be, high pressure pump or spark plugs/spooling? What else? I absolutely need your help, will not give up my little ones have really gone through a lot with each other but he is now also s chon 157,000km….
