Hello together, I’ve got a problem with my 6s and it all started very small.. The MKL went so much like that during the ride?? No power loss or anything else…it’s got to be easy to get rid of the engine. I can get rid of the engine engine error: 1) VANOS-magnet valve inlet camshaft mechanical clamps 2) Synchronization camshaft to KW value out of range. These two errors were shown again. So next theory: It has to be either the adjustment unit inlet NW or chain too long. So we have ordered this adjustment unit and have to change the head and/or the lid of the engine before it was at least one year ago. Chain sits tight, but the engine is full with hard slime – lt. Workshop master has not been made a change of oil for a long time. I have to say that I have changed the car for half a year and has got to get rid of it.
