Hey, one injector seal has failed and caused the following: Hot gases escaped through the injector and damaged the plastic manifold and its gaskets which lead to this carbon ‘build up/splatter’ Injector seal replaced with plastic manifold and that was that. It is a pig to remove the hard mass so just left it there as it doesn’t really do anything - just looks unsightly. Hope this helps.

Hi Hope someone has some ideas and can help me with the below please? Audi A6 avant c7 v6 3L TDI I have noticed a black splatter around the coolant reservoir and top engine cover. Upon further inspection noticed a black mass of more of the same around where exhaust is coming out of the engine. It is totally solid/hard. What is that? Engine runs ok apart from very rare juddering on cold start and some coolant disappearing overtime. (Like 200mil over a month or two) No leaks of any sort noticed This black hard mass looks worrying 😞 No loss of power, no overheating, coolant reservoir nice and clean, oil cap clean, no bad smoke coming out of exhaust- none of the worrying bits if you know what I mean? Any help would be much appreciated. See pictures attached.
