Title: Help clearing DTC errors APY to BAM S3
Post by: pompak on August 13, 2017, 05:25:48 AM
Hello.
I need help with the Audi S3 1.8T APY 210 ps. Orginally there is a computer with 512kb memory and a narrowband lambda sensor. I changed the computer to BAM 1024 kb with a broadband lambda probe, put the wires into the ECU, everything works, the map was made, Audi accelerates about 5.8s to 100km / h. Unfortunately I have DTC errors and I can not turn them off, will somebody help me? Ecu immo off
Exactly:
17526 - Oxygen Lambda Sensor Heating B1 S2: Open Circuit P1118 - 35 -
17939 - Camshshaft Timing Adjustment: Open Circuit P1531 - 35 -
18058 - Powertrain Data Bus: Missing Message from Instrument Cluster P1650 -35-
17863 - Exhaust Gas Temp Sensor 1 (G235): Implausible Signal P1455 -35-
Sometimes there are also:
17705 / P1297 / 004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
Auto then loses power, DV replaced, leak tested, where does that come from?
I would ask for help removing the DTCs from the map or possibly throwing them out of ECU Lambda 2 and Exhaust Gas Temp, and Camshaft.
Regards, I attach the current flash

Thanks, I learned a lot from this site, I erased DTC errors and egt sensor, but there is another problem after running about 1km appears:
16396 - Bank 1 Camshaft A (intake) Advance Setpoint not Reached (Over-Retarded) P0012 -35 -
What do I have to change in the map to not display this error? I do not understand the description of s4 wiki VVt with DTC is erased, probably loses power as this error occurs

Have you tried ESKONF to tell the ecu what is installed and what is not installed hardware wise?

you are plz read more this site and find the solution

short time melt the engine
