Title: Golf MK1 1.8T AUM conversion DTCs Post by: esacul on August 10, 2020, 03:42:33 AM Hi, for the past 1.5+ years I've been working on a Golf MK1 cabriolet 1.8T AUM conversion. Just a few days ago I finally got it running (ME7.5) :). The ABS, Instrument cluster and other CAN controllers are not installed so I had a a few DTCs, and the car is running in limp mode.
What I have done since the first run: - Change power output configuration (ESKONF) - Delete post cat lambda (CWCS) - Immo off After a second run, only these are left: P1523 0x64 Crash Signal from Airbag Control Unit P0600 0x68 Serial Comm. Link (Data Bus) Message Missing P0600 0x64 Serial Comm. Link (Data Bus) Message Missing Could anyone point me in the right direction to get rid of these? I read something about CW_CAN_R but in the definition file I am using there are many (CW_CAN_R_0, CW_CAN_R_1, etc). Also, they have values in the ~5000 range if I remember correctly, so I am not sure if these are the correct addresses. The XDF I am using is for a HN (converted from a kp), I have a 06A906032HJ ecu. Attached is the bin file. The XDF definition is on a different computer that I dont have access to at the moment. Help would be appreciated. Kind Regards, Eric Title: Re: Golf MK1 1.8T AUM conversion DTCs Post by: BlackT on August 10, 2020, 04:43:50 AM CWCS is for code out airbag
CW_CAN_R set all to 0 Title: Re: Golf MK1 1.8T AUM conversion DTCs Post by: esacul on August 10, 2020, 05:23:15 AM Oh yes sorry, my mistake there. CWCS has nothing to do with post cat. Forgot to mention I have set CWCS to 0 already in an attempt to get rid of P1523, but it seems I'm still getting the P1523 DTC after that. I'm working at the moment, will verify later if it really is 0. Maybe I forgot to save after changing it.
So all CW_CAN_R_x to 0, okay. I just hope the addresses in the definition file are correct, I'm not sure how I can verify that. I guess I could compare with other bins. I'll give it a try soon :) Thanks! Title: Re: Golf MK1 1.8T AUM conversion DTCs Post by: BlackT on August 10, 2020, 05:44:50 AM Post mappack, I will check adress

Attached is the definition file that I am using. I did a search on CW_CAN_R and found the following: CW_CAN_R_0___A CW_CAN_R_0___A CW_CAN_R_0___A CW_CAN_R_1___A CW_CAN_R_1___A CW_CAN_R_1___A CW_CAN_R_2___A CW_CAN_R_2___A CW_CAN_R_2___A CW_CAN_R_3___A CW_CAN_R_3___A CW_CAN_R_3___A All these have to be set to 0, is that correct? Thank you, I appreciate it. Title: Re: Golf MK1 1.8T AUM conversion DTCs Post by: BlackT on August 10, 2020, 06:48:09 AM Your CWCS is at 0x1A5E0 WRONG
It is on 0x101AF CW_CAN_R also wrong these are correct CW_CAN_R 0 at 0x132AC CW_CAN_R 1 at 0x132AE CW_CAN_R 1 at 0x132B0 CW_CAN_R 1 at 0x132B2 Out of curiosity, how do you check this if I may ask? Yust a hours and hours of reading this forum, it is all there, yust you must put in a effort. Then you will learn allTitle: Re: Golf MK1 1.8T AUM conversion DTCs Post by: esacul on August 10, 2020, 08:05:42 AM Okay, thanks BlackT, I didn't know the address of CWCS was wrong, the value at that address seemed to be correct. I would like to learn how to find these addresses / locate the tables in the bin so that I can verify and correct them.

As I say, lot of reading and lot of practice and with time you are going to get itTitle: Re: Golf MK1 1.8T AUM conversion DTCs Post by: esacul on August 11, 2020, 08:25:31 AM I probably could find maps by comparing with other bins or by using WinOLS. Still unsure how one would find constants like CWCS though.
Anyway, I used the addresses For CW_CAN_R_* and CWCS that you found. And set them to 0. All DTCs are gone, except for P1523. Any idea why? I’ll post the bin later.

Today I did a test drive (finally), and found out it had no boost. I got a few other DTCs that I need to code out (not sure how yet). Could they cause the car to go into limb/protection mode? I'm getting the following codes:
P0441 - EVAP incorrect flow EVAP is not installed in this car, might install later but for now would like to code out if that's possible. P0140 - O2 bank 1 sensor 2 no activity Need to code this out, post cat O2 is not installed. P0501 - Speed sensor implausible signal ECU speed signal wire is not connected, I am using an analog speedo cable for the Golf MK1 cluster (so no electronic speed sender). I will be getting a hall sensor for the MK1 speedo clock so that the ECU gets a speed signal. As far as I know the signal is only needed for launch control and cruise control, correct? For now I would like to code this out too if possible. Can any of these cause limb mode (no boost)? Help would be appreciated, thanks.

Did you manage to get it running right ?
