To mitigate the problem the cleaning process as well as a new camshaft plug was introduced in engine plant at engine number - 04010816353.
Note:
The first 6 digits in the engine number indicate production date (format ddmmyy (0401O8xxxxx) and the last 5 digits is the serial number for that day.
This means that:
