Or you have suffered a hydro block, caused by the defective Egr Coolers this cars have, that cracks and leaves pressurized cooling escape inside cylinders… happened to me..
Result: crankshaft bearings damage…solution new (used) engine. Now i change the egr cooler every 100,000 kms.

Or you have a timing chain failure..
