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 - Huh

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

Use a more well defined file, like 8DO - 551M

551m is 1mb ECU, my ECU 512kb
Stupid question, I have spare 1.8t ECU with 1mb flash. Can I replace 29f400 to 29f800 and flash it with 551m file?
