Cel light and codes p242f and po299 on ,clear and they come back,replaced diesel part.cat with new already
Expert:  Hipo64 replied 1 year ago.
Hi and Welcome to Just Answer! my namee is Pavlin and I will do my best to help you with your question. You have 2 different issues Here.
P242F is excessive ash acuumolation. If you have replaced the filter already, next is to use manifactured compatible sc an tool and reset all adaptive parameters and tell computer that filter was replaced.
If you do not do that code will not go away.
second code is for Turbo boost pressure below normal.
if code comes back immediatelly even if engine is not running, then you have problem with Boost pressure sensor or atmospheric pressure sensor performance. atmospheric pressure sensor is the mail input to ECM. ECM compares this pressure to intake manifold pressure. check if sensor readings are correct.
if not replace the faulty sensor. with engine not running both sensor shoud read atmospherik pressure which is equal to 1 bar or about 14.7 psi
Best Regards Pavlin!

Expert:  Hipo64 replied 1 year ago.
Hi, for first code you have to do reset. For second code it takes time before computer see the conditions to set code. You have no power due to first code.
