overboost problem

[brianb]

Had trouble with my s4 for a while now,ive checked/changed the wastegate/wastegate diaphram/n75/pipes around the turbo wastegate/n75,up until the other day i was only getting the 00544 35-10 code but now another one has appeared relating to boost and also the cam position sensor is throwing up a code(i only replaced it recently as it was giving the same code).It is boosting upto 2.5 bar on the lcd gauge in the dash,i know this is only 1.5 in reality

00544 maximum boost pressure exceeded
35-10 intermittent

00544 maximum boost pressure exceeded
27-10 implausible signal- intermittent

00515 camshaft position (hall) sensor-intermittent
20-10 malfunction in basic setting-intermittent

cant find much info in the search regarding the 00544 codes and even the rosstech website doesnt show it,can a faulty ecu cause this??

Sounds like the same problem another forum member is having. He found one of the small pipes from the wastegate broken down.
