2453 is theor paticulate soot filter and 244 is just the restricted performace differential pressure sensor, needs to b e serviced for sure...

Both these codes relate to Catalyst efficiency below threshold on banks 1+2. This is normally caused by a combustion fault. This fault may be shown due to a faulty sensor in either air imput or exhaust systems, Get the memory read at a dealers or good garage. If you had a serious problem the car would not drive well.
Hope this helps - good luck.

Code PO430 could be = catalyst efficiency below threshold bank 2 ........ this may be caused by faults in combustion and if you have just completed repairs it may rectify itself as the car runs correctly ...... do not leave as a fault for too long as damage will occur to cat/conv.
