Title: A4 B6 2.7TT swap issues - EPC Post by: envisible on November 05, 2017, 02:57:31 AM Hi
I swapped AJK (2000 eu A6 MT) engine in my a4 b6 1,8T quattro MT, AMB engine. It starts and run Ok, speedo, tacho, ESP works fine, but I have EPC lamp on cluster and DTC in ECU 18084/P1676/005750 - EPC Warning Lamp (K132) Circuit: Electrical Malfunction I found, It's a pin48 on ECU, It should be connected to instrument cluster, but 8E cluster has no pin for EPC lamp, unlike 4B cluster. I guess 8E cluster communicates with ECU just only CAN or/and K-line and receives MIL and EPC request via these lines. How can I solve these problem? I think my 2.7 ecu doesn't have MIL, but I would like to have working EPC lamp. I tried to connect pin48 to ground or kl.30 via resistance, but no success. I tried to code out EPC lamp circuit diagnosis in ESKONF, but I couldn't find Bit to disable. Orig file attached, I found ESKONF at 14F46 And I need to confirm some maps, please CWSAWE - 15498 KFNWEGM - 19758 KFTVSA - ??? Thanks in advance Upd: EPC lamp Ok! pin48 to kl.30 via 10kOhm resistance And it works fine, no lamp on normal condition, when disconnect throttle connector - EPC on Still need for maps Title: Re: A4 B6 2.7TT swap issues - EPC Post by: nyet on November 05, 2017, 09:15:53 AM Still need for maps Use a more well defined file, like 8DO - 551M Title: Re: A4 B6 2.7TT swap issues - EPC Post by: envisible on November 05, 2017, 12:02:22 PM It’s not easy to find s4 b5 Ecu in our country(

Stupid question, I have spare 1.8t ECU with 1mb flash. Can I replace 29f400 to 29f800 and flash it with 551m file?
