i have overboosting problems with my s3. It is 210HP engine, year 2000.
This is fault code:17963 - Charge Pressure: Maximum Limit Exceeded
P1555 - 35-10 - - - Intermittent
Car isnt chiped yet, but it has FMIC, 007p DV, deleted N249, bigger intake manifold and milltek catback (decat with 2.75" downpipe). All hoses seems to be OK, i replaced LMM (maf sensor) and n75 with new OEM. I have boost gauge and it is boosting over 1.3bar, car goes into limp mode only in 5. gear at around 5200rpm. Did anyone had the same problem on standard map? I have also disconected n75, it's the same, only difference is that it goes to limp mode in 3. and 4. gear also . Boost is the same. Turbocharger has been renewed 10.000km ago, but i assume that actuator isn't properly configured or it is broken. i will be fully grateful for your help.
