So maybe if you get the ability the find it in the TCU maybe its can be in there. Or is it hidden in other parts of the ecu that we would need to find. When I search 0741 in winOLS that's not the dtc in the table from what I'm to understand. Also I see in my file you modded u disabled p1624 and that still didn't stop the light from coming on.

p0741 isn't in the ECU, it's thrown by the tcu. That, and search as I have I've been unable to find any sort of dtc table in the TCU files I have (and I have a lot). Honestly, it's not worth the time trying to hide that code. Put the stock tune on your car that DOESN'T cause the TC to slip, and run it like that if you don't want the code. When you have the money, then fix it right.

I will try to clarify the information.
Procedure with WinOLS:
First, please note the following addresses:
DTC Error Code Class Table (8 bit table) 0x106AD
DTC Manufacturer P-codes (16 bits values) 0x12CC4
DTC CARB P-codes (16 bits values) 0x1324C
For example, to disable the following code:
17522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
P1114 - 004 - No Signal/Communication
In WinOLS, use the following view: 16 bits, LoHi, FF
Search for an hexadecimal value of 1114 in the first table.
Note: Since it's a Manufacturer P-Code, the error only appear in the first table
You will find 4 occurrences at the following addresses: 0x12EDC, 0x12EDE, 0x12EE0, 0x12EE2
Make the following calculation:
( addresses of the first occurrence - address of the associated DTC table) / 8 = index
( 0x12EDC - 0x12CC4 ) / 8 = 0x43
Now, 0x43 is the index of this DTC in the Error Code Class table.
Determine the address of the value to switch off the DTC
0x106AD + 0x43 = 0x106F0
Now, change your view in WinOLS to 8 bits, go to this address and change the value at this address to to 0
Since I don't have an S4, I will test it with my 1.8T this weekend. I will disconnect the 02 sensor and try to disable some codes.
Thanks, a very informative post. Im new to this hex thing, I am looking at an 018H TT file and have found the address of the dtc in 16bit . Im looking to get shot of the P1523 and p1807 I cannot find the appropriate DTC Error Code Class Table (8 bit table) to allow me to then /8 to set the location of the DTC trigger byte currently all i have is DTC location of 1076c I cannot get my head around finding the error code class table. Anyone willing to give me some education into this please?  018h file |

I have a newer map pack that has the actual (fehler) code listed as a 1x1 is it as simple as zeroing that out now its defined? I am making the assumption that the maths bit was to locate the specific byte to change given it may or may not be identified in the map pack

Yes, zeroing the fehlerclasse will remove the code. If you want, post your file. I'll tell you where the tables are.

it looks like the Fehlerclasse for 1523 is located at 10954 according to my map pack under DFPM_GGCS Ccash signal
I;m going to try this and will report back, ny bench cable isn't here so don't want to flash a file without it in case of something going wrong.

Hi, we talking actual zero or FF, I'm quite new to this hex stuff |

Does zero sound like FF?
But seriously, The block should contain a bunch of 00, 03, 13, etc. Just 00 whatever you want to remove.

No it doesn't,  But i have worked with some dubious people that seem to fill files with FF's for a pastime to remove stuff Thanks for the help Hmm it seems i have "located" the wrong bit going by your description. Thanks for the help so far So with this in mind I had the wrong location, I believe this is the right one now....? Maybe 10873 |

1070F is the start of your error class table.
Hint: There's almost always a 01 7F in front of it. A lot of times 01 7F 0F 00, where 00 is the start of the table. Some files this is 01 7F 50 00. Yours is 01 7F 00 (again, 00 is the start of the table).
Alright, to walk you through this:
P1523: The first occurrence is at 1361C. Scroll up until you see four blocks of 0000. The address of the first block is the start of the VAG specific DTC table. In your file this is 1327A.
Now:
1361C-1327A=3A2
3A2/8=74
Now find the start of the error class table.
1070F+74=10783
00 the byte at 10783 (it's got a hex value of 13 in your file) and you've removed that specific code.
The second one, P1807 isn't an engine code. It's stored elsewhere, and can't be removed in this fashion. If the engine gets a code that says "Check Transmission computer for errors" (for example) you can remove that, but it won't keep the engine light off. It'll just prevent an error from being displayed when you scan for codes.

Ahh that'll be some odd typo i managed to do, it should be P1650, any chance of a pointer to confirm what i have found please. I don't seem to be able to find the four blocks of 0000 just now. Maybe I have hex blindness |

Select 16bit, and go to 1327A. There will be 4 blocks of 0000. To delete it yourself you need to find ONE address. That's easy. Come up with where you think it is and I'll confirm. |

Tried this method on a ME 1.5.5 and works fine. Unplugged the EGR and no DTC Error.
