Hi there, 

Random question, so this foam has appeared on the outside of the engine, next to the drivers wheel. It looks like it has consumed the connector also. Any idea where this is likely to be coming from ??

Yesterday I had to add oil and coolant, not normal for this car. But one the cylinders appears to have gone and it sounds like the DMF may also be on its way out ?? Is there any chance that it's connected to a singular point of failure or has everything gone at once ??

    Did you add the oil & coolant together?  Looks like headgasket failure 'milkshake'.

    Lol, just checking. :wink: 

    It'll be coming out of the waterpump or the crank seal if it is headgasket milkshake.  Can't see specifically where it's coming from on that photo unfortunately.

    If the coolant reservoir isn't full of it, then check the oil dipstick carefully, don't wipe it the first time you pull it.
