Good evening, I have the following problem with my 750i Bj 2010. The vehicle is in emergency run and was throttled by the system. According to BMW error diagnosis the cylinder had 5 and 7 false ignitions, so with all 8 cylinders the spark plugs were replaced and with cylinders 5 and 7 the ignition coils. The spark plugs from the engine compartment seen from the left side were all very good deer brown. On the right side were 2x white, brownish, 1x black, and 1x deer brown. it was deleted and for 500 meters everything was gone. Now I have read out the error it came: P0025 and P13B7. I have both noted and deleted P0025 has disappeared P13B7 remains still engine control light is on!. Besides, it loses cooling water since being replaced by BMW the water pump and some hoses. Yesterday I replenished 1 liter of oil, today the message came again 1 liter, I did then was quiet today. Maybe I filled too little. After turning off the engine Clackles for about 3 minutes the balance tank of the charge air cooler. Does anyone have a tip?. Thank you…
