Hello together, I have had a strange problem with my R for a few days. The engine started to stutter easily at 50 km/h driving speed (so from 2000 rpm) and later 1-2 kilometers also the EPC and motor control light went on. For me this felt as if the car was running in the emergency running program and only on 7 cylinders. Did anyone ever have this problem or can tell me what was defective? I read out error memory today and this came out: Address 11: Motoreektr onik 2 Label file:. 079-910-560-BYH2.clb Part number SW: 420 910 560 L HW: 420 907 560 Component: 4.2L V8HDZ/4V FS a0030 Revision: 5DH09— Serial number: AUX7Z0H3FN30G2 Coding: 011000031B0F0120 Operating no.: WSC 00243 211 79472 VCID: 176A3F1FC3810A8F4F7-8042 3 Error codes found: 000768 – Burn breakers detected P0300 – 001 – Environment conditions: Error status: 01100001 Error priority: 0 Error frequency: 2 Leverage counter: 255 Kilometer: 80792 km Time indication: 0 Date um: 2019.03.08 Time: 13:06:36 Ambient conditions: RPM: 1841 /min Load: 44.7 % Speed: 33.0 km/h Temperature: 95.0°C Temperature: 20.0°C Pressure: 990.0 mbar Voltage: 13.716 V 000772 – Cylinder 4 P0304 – 001 – Combustion breakers detected Ambient conditions: Error status: 01100001 Error priority: 0 Error frequency: 2 Learning counter: 255 Kilometer: 80792 km Time indication: 0 Date: 2019.03.08 Time: 13:06:36 Ambient conditions: RPM: 1841 /min Load: 44. 7 % Speed: 33.0 km/h Temperature: 95.0°C Temperature: 20.0°C Pressure: 990.0 mbar Voltage: 13.716 V 004874 – Cylinder shut-off P130A – 001 – – Sporadic Ambient conditions: Error status: 00100001 Error priority: 0 Error frequency: 1 Learning counter: 255 Kilometer: 80816 km Time specification: 0 Date: 2019.03.12 Time: 10:27:16 Ambient conditions: Speed: 2012 /min Load: 34.5 % Speed: 49.0 km/h Temperature: 95.0°C Temperature: 15.0°C Pressure: 1000.0 mbar Voltage: 13.843 V According to the error memory, what is wrong with the 4 cylinder, has already ordered a new ignition coil and spark plug, will then report if the problem is gone.
