Good day guys,
checking again with porsche diagnostic tool error codes appear(this time) are:
PO102 Hot maff sensor
P1101 input variables,charge measurement
P0175 oxygen sensing adaptation idle range bank 2
P0172 oxygen sensing adaptation idle range bank 1
Old maff measurement 1.12V
New maff measurement 1.32V
maff already changed 3 times(original bosch)
Intake leak tested once(one heavy leak found in port side turbine/intercooler hose colar which arrested).
Air filter installed is new.
If there is another small intake leak do you have any idea of where it might coming from??

P0102: 115 Mass air flow sensor – below limit
Possible fault cause
♦ Open circuit
♦ Short circuit to ground
♦ Mass air flow sensor faulty
P1101: Input Variables, charge measurement below/above limit
Possible fault causes:
1 Heavily soiled Throttle
2 Throttle adjusting unit faulty
3 Mass air flow sensor faulty
P0172: Oxygen Sensing Adaptation, Idle Range, Bank 1 –
Below Limit
P0175: Oxygen Sensing Adaptation, Idle Range, Bank 2 –
Below Limit
Possible fault cause
♦ Incorrect signal from MAF sensor
♦ Fuel pressure too high
♦ Fuel injector leaking
♦ EVAP canister purge valve open
Which Bosch MAF are you using?
PN: 996 606 124 00

I. Am using bosch
0 280 218 009
996.606.1224.00 same part number as the one you describe.

Good day Mr wross996tt,
i would like to thank you all for your feedback.Finally my problem was solved.Throttle found to be dirty(very thin black carbon/oil film layer) which was creating problems during low RPM where the throttle dumper is almost close.Car now is working perfectly.
