Hello im owner of saab 9-3 estate late 2007 im looking for advice here because have the same engine.

Problems start with code P2279 engin on poor perfonmance and finally wont start.
-egr and solenoid clean
-Throttle was clean
After this engine start but still less power so go to garage and guy was done forced clean for dpf 0%
i bought fiat gasket for egr
After 3 days on bypass i get spanner and limp mode so connect opcom and get
P242F-75 so delete this, car back to normal ,back to motorway to check if happen again and it is another 3 times also get one time code P242F-58.
Back home and check in opcom dpf it was about 35% and last regen. about 530 km ago.
Read from opcom for egr is:
Contracted position EGR (Exhaust Gas Recirculation), 100%
Pulse Ratio EGR (exhaust gas recirculation), 4%
i do not know if this is right value..

Do anybody know what it is?
