hmm I sitting here now biting my nails... what could it be.. When I erase the code it runs super for like 1-Min.. So practically the circuit works.. But there is some bloody thing the ECU dont like here.. A grounding problem maybe or something.. What if I just disable the code on Pre-Cat sensor.. hmm..

Dont disable codes, find out what the error is! Is the sensor new? Does it work well with a standalone controller? All wiring okay? Also could be the ecu is faulty

Well as you say i suspect its the sensor now.. I checked all wiring and power supply and did find anything. The sensor might be the problem its a used sensor i took from the scrap yard this might be the peoblem.. Im gonna se if i can get a sensor quick somewhere..  Its strange because it worked with my innovate MTX-L... Maybe I should try it again there. |

I did a test with another used LSU4.2 sensor.. same result. When at idle everything works as normal but direct when i start to drive the car it shuts of cloosed loop..  I starting to think its my software version or something.. The ECU initially used 06A906032HJ 0002 But i flashed another 06A906032HJ Stage 2 version to the ecu. emission Readiness Secondary Air sys: incomplete O2 Sensor: Incomplete O2 Sensor Heater: Complete |

No resistors needed, I run a AEB with APU harness on a ATW ecu now  Not a single resistor used, just added wideband wires and coded out anything I did not need. I'm currently running an AEB. Is this the easiest harness + ECU combination to use when converting? |

If you run AEB its another story i think. Diffrent harness.

APU harness fits AEB more or less (both 058 block) I had to change only oil pressure sensor and adapt plug of alternator. I installed tfsi coils shortly after and as last mod added wideband wires/changed to b5.5 ecu

I revieved my cable and everyting was connected as supposed to.. I Tried a diffrent sensor but same result.. This other sensor was also used though so.. A new sensor will arrive this week.. But i still cant grasp why the sensor is Alive and sending accurate values.. It gives me a worrying sense.. hmm
P0130: O2 Sensr Circuit malfunction.
Heater Coupling Check (P0130)
This monitoring will detect any short circuits between sensor heater and the Nernst cell of the Oxygen sensor by monitor the Lambda signal. The amplitude signal of Lambda is untypical and changed in the same velocity than heater duty cycle.
Signal activity and rationality checks (P0130)
The Lambda value of oxygen sensor upstream catalyst is compared to the sensor voltage downstream catalyst. Additionally, a check is performed by checking the sensor voltage range. Three diagnostics paths cover the air fuel ratio range of Lambda value (e.g. Lambda=1, lean, rich). A corresponding reaction of sensor voltage downstream catalyst is expected.
The criteria for sensor readiness of a binary sensor are:
• No fault from heater final stage check
• Sensor signal is out of a range 0,4V<sensor voltage<0,5V
• Heater power > 50% within a certain time (typically 8-10 s)
The criteria for sensor readiness of the linear are:
• No fault from LSU-Heater, LSU-Signals and LSU-IC
The criteria for sensor readiness of the linear are:
• No fault from LSU-Heater, LSU-Signals and LSU-IC
• LSU is heated up to a ceramic-temperature of > 685°C or the internal sensor resistor Ri < 130 Ω.
Could it be my secondary O2 sensor? Looking att diagram.

Hmm I have had o2 codes when I first set up my mapswitching on the rear o2 input. There is a case where a fault code is set when secondary lambda gives a high value for x seconds while primary sensor is showing a lean condition. Or something like this. But I dont know if it was this exact p number..

Ok. Well i have looked at what pther people do and I think i must use pin71 i thought it was plugged but stupid me i didnt realize it is wired inside the LSU connector. So i will wire pin2 to Pin71 on ECU. Thia must be the problem lol. Ahh cool to use O2 S2 input to switch maps. I need to learn how to code later ...Could that input be used to logg let say EGT 0-5v with correct scale factor. |

Problem solved it was pin 71 tha wuas needed. Runs like a charm... pulls retally nice on a Stage 3 file. |

Hello guys,
I will swap my 1.8T AJQ to BAM with VVT. I already bought ECU from BAM and added wires for new o2 sensor
Where can i find which cables i need to add to get VVT working? which plugs do i need?
Thank you in advance

Did you use resistor with this or just directly wired to pin 71 on ecu ? as im about to do the same thing. Problem solved it was pin 71 tha wuas needed. Runs like a charm... pulls retally nice on a Stage 3 file. |

You don't need to put resistors anywhere just get an LSU4.2 connector and connect the wires to it.
