4. All V8 - Otto - Engines
Ignition module with part numbers 077 905 115 C, 07C 905 115 D, 077 905 115 C, 077 905 115 E or 077 905 115 F from 2003 onwards

Solution:
When the ignition coil is faulty, the combustion points are only stored on one cylinder.
Are the misfires stored on multiple cylinders, other causes for the error code entries could be responsible. (e.g. Incorrect air intake, camshaft adjustment, fuel system)

Exhaust gas emissions control systems can have many causes (e.g., (Fuel injector), but not always is the distributor ignition coil responsible for this.
