So my AUM 1.8t is running like absolute crap and I'm unsure as to what I should do next. The car is reluctant to start, but it will and when it does it idles pretty much fine (odd jitter here and there, nothing worrying) but as soon as I try and take it for a drive it's so down on power it feels more like a 180cc car than a 1800cc car (literally struggles to get up a hill!)
I've run the car through VCDS and a preliminary scan gave me the following fault codes:
5 Faults Found
16621 - Manifold Pressure / Boost Sensor (G31): Signal too Low
P0237 - 35-00 - -
16490 - Manifold / Barometric Pressure Sensor (G71) / (F96): Implausible Signal
P0106 - 35-00 - -
16727 - Camshaft Position Sensor (G40): Signal too High
P0343 - 35-00 - -
18041 - Accelerator Position Sensor 2 (G185): Signal too Low
P1633 - 35-00 - -
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-00 - -
I then cleared all faults, started the car, took it for a drive again and got the exact same faults. It's interesting to note that this is a recurring fault that will come back the second I have cleared all faults (even if the car isn't started!)
Fault Codes have been Erased
1 Fault Found
1 - Manifold Pressure / Boost Sensor (G31): Signal too Low
P0237 - 35-00 - -
Everything is wired up correctly as far as I can tell... any thoughts as to what is up? can this fault cause my car to run like absolute rubbish? or could it be something else?
I've uploaded a video to try and demonstrate the problem, note I'm full throttling the car both times I hit red-line. The first time I rev it seems to be okay, the second time it's a jittery mess that doesn't seem to want to be revved:
