Ever since I got my RS2 setup ABY mapped i have been facing hard times. The first test drive set the boost dial to 1.8bar and I smile on my face, after that i lost cyl 5 coil and all was no go.
Then i binned all the old spark/coil stuff and made a harness for 2.0TFSi coils. All felt right again, except the boost that did not go higher than 1.5-1.6 anymore (still pulled strong).
When I pulled the codes it gave me this:
00537 - Lambda (Oxygen Sensor) Regulation
08-10 - Control Limit Surpassed - Intermittent
The car stalled few times when going form engine brake to clutch... -> doesn´t do that anymore, also the fault code is gone. Now it only hits 1.1-1.4 (holds 1.0) and it doesn´t feel that strong anymore
.
Did test boost leaks by pressurising the maf hose and blocking the intake hose and the vacuum hose to the head. Sounded like the air was leaving the engine throw the wastegate (think through the N75, is this normal when tested like this?)
How can You test for boost leaks from the pressure side of the turbo? There is no room to put my test equipment or is there?
Tried the mechanical boost by taking of the N75 connector and the pressure rised to 0.5. Should it be 0.4??? The wastegate cover looks intact (not drilled).
Today I pulled the codes after the pressure test and it showed as follows:
00524 - Knock Sensor 1 (G61)
03-10 - No Signal - Intermittent
Erased the codes and drived the car to read the codes again but the fault code was none. It feels that the car is on limp mode but can I pull some log of the vagcom to verify what to look next? Could it be good to change the knock sensor G61 ( I think itś orginal 212tkm) When driving on part throttle the car feels like it´s going back and forwards (must be lambda adaptation of some sort?). It goes good all the way to the redline put the Going is not so hard that it used to be And the boost get´s a litle bit off a low side in my opinnion.
Many questions here, any help would be appreciated

(Not my daily driver).
Is there also the fuel pressure reading throw the Group 000? or do I need to accuire separate pressure gauge?
