Hey, but I have the following problem Since recently flashes and lights up the MKL, When I put the ignition cables out of the cylinder and plug in again the engine starts to jerk strongly only at the 3rd cylinder does not jerk, therefore the realization that the car does not ignite in the 3rd cylinder. Then to the workshop to let the error read again and the guy meant what I suspected and was ignition oscillator in the 3rd cylinder and that it can only be the ignition coil, I ha a new ignition coil, 4 spark plugs and a new set of ignition cables ordered. Result : continued ignition oscillations in the 3rd cylinder. Now started to another workshop, problem described and this meant now that it is on the piston ring and this has to be renewed, since I changed the spark plugs these were strongly oily. Now my question you mean that it can actually lie on the piston ring, moreover I also have the assumption that my valve lid seal also I’m rather perplexed and would hate to put more money into the car if it can still be something else in the end. If desired, I can also upload pictures Sincerely
