2018-19 Mercedes-Benz C217 S-Class Coupe: oil lines could leak
In March 2020, recall campaign RC2764 was issued for Mercedes-Benz C217 S-Class Coupes that were available for sale in Australia from 1 August 2018 to 30 April 2019. In these vehicles, materials used in the oil lines may not meet the correct specifications – this could result in oil leakages while the vehicle was in operation. If a leak occurred, oil could come into contact with hot components of the vehicle and cause a fire – this posed a risk of serious injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see PRA 2020/18261.
2017-18 Mercedes-Benz C217 S 560 Coupe: oil leaks could cause engine to engine to run dry
In August 2020, recall campaign RC2788 was issued for Mercedes-Benz C217 S 560 Coupes that were available for sale in Australia from 2 October 2017 to 28 November 2018. During hard driving, the closure material of the engine plugs may fail as a result of high engine oil pressures – this, in turn, could cause oil leaks. If enough oil leaked, a red warning message would illuminate in the instrument cluster. If the warning message was ignored, the engine could run dry, causing it to stall and sustain damage – this increased the risk of a collision for vehicle occupants and other road users. If oil leaked onto the road, it increased the risk of collisions, posing a risk of injury for other road users. For the VINs of the recalled vehicles, please see PRA 2020/18484.

Mercedes-Benz C217 S 500: engine rattle noise after start-up
In December 2015, Mercedes-Benz issued Service Bulletin LI05.10-P-056435 Version 10 for Mercedes-Benz C217 S 500 Coupes that had M278 engines with engine numbers up to 2789xx 30 191843.
According to the Service Bulletin, the driver may hear a rattling noise after start-up – from the engine compartment – that lasts for several seconds. This noise was attributed to a lack of oil pressure in the secondary chain tensioners, though Mercedes-Benz claimed that no consequential damage was to be expected.
To fix, the secondary chain tensioners (left and right) were to be replaced and a check valve was to be installed in the oil supply bore of each secondary chain tensioner in the cylinder head (left and right).
