If it is of your interest, my A6 is MY2010 and my 5F codification is this:

Address 5F: Information Electr. (J794) Labels: Redir Fail!

I hope this can help tou,

Thanks! It looks like your 5F module is a later revision than mine - yours is 4E0 035 666 C and mine is 4E0 035 666 B

I don't get any issues with the 5F at all - just this error reported in VCDS. I only have the car for another two months, so I guess it will never get resolved.

Cheers!

MF.

Can You gentily post all the ECUs codification with VCDS using the function scanner ?

I've an A6 Avant TDI 2.0 170cv as you and I wish to add the functionality: AHA (Audi hill Assist). i think it is a codification of the ABS ECU (addr. 03) but i don't know which are the right bits ...

I think that in UK, AUDI enable this feature automatically and I whish to add it on my car.

Can You help me please ?
Enrico.

[MFGF]

None of the A6 4Fs over here in the UK have hill hold as far as I know - I have never seen it offered as an option.

I can happily post the coding of my ABS module, but it will not really help you I imagine - my car does not have hill hold.

It is now a standard feature on the new 4G A6s, but they are a totally different car.

Many thanks MF,
I know that A4 (B8/8K chassis) and some A6 (4F-C6 restyle, like mine) has this option anabled. So I think that it is only a different codification of the ABS module. Now if your A6 does not has it, it is not necessary that You post your ABS codification.

The same thing is for some features anabled into the 5F module. For example,did your audio system has some DSP effects ? Your audio system is composed by 8, 10 o more speakers ?

Thanks again,
Enrico.

Hi
MFGF
Did you get 01043 - Control Module; Incorrect Software Version resolved?

There is a way to clear this fault you need to read
[Adaptation - 10] -> Channel 15

Value should be 0 count number is important
Take your count number and do some sums.
if count is 2164 adapatation value is worked out like this
2164 xor 51666 = 49574
49574 is the adaptation value....51666 is always the same

Hi Andy,

Ok. This is officially weird. I just went out to the car armed with this information and my VCDS on my laptop. When I scanned the car before starting any changes, it reported no faults across the board! Specifically, the results for the 5f module looked like this:

-------------------------------------------------------------------------------
Address 5F: Information Electr. (J794) Labels: 4E0-035-6xx-5F.clb
Part No SW: 4E0 035 666 D HW: 4E0 035 666
Component: H-BN-EU H64 0143
Revision: -------- Serial number: 345BY097545942
Coding: 010101000102C3ED01000315EF6300030001
Shop #: WSC 00778 210 97003
VCID: 2756F15056F635B
Subsystem 1 - Part No: 8R0 060 884 R
Component: EUR 2010 1107
Subsystem 2 - Part No SW: 4F0 919 604 HW: 4F0 919 604

Subsystem 3 - Part No SW: 4F0 910 609 E HW: 4F2 919 611 M
Component: Bedienteil MM H01 0060
No fault code found.

This scan result looks entirely different to the way it used to!

I was intrigued, so I went to look at the values in Adaptation channel 15. My count number is 10420, but the stored adaptation value is 0. According to the calculation, the stored adaptation should be 55702. No errors are reported, though. Very weird!!!

The car was in at my dealer for service last week - I wonder if any kind of software update was done which may have fixed the issue? I checked my installed version, and it reports HNav_EU_K0031_3_D1

Because no error is being reported, I have not changed the adaptation value. I will keep an eye on it over the next few weeks and see if the error returns.

The only other change I can think of is the version of VCDS - I am now on the following after the latest update:

VCDS Version: Release 11.11.2 (x64)
Data version: 20120126

I now have a labels file for the 5f, whereas there wasn't one available back in February 2010 when I first recorded the scan in VCDS 908.1. I don't see how this could have had any impact on the error, though.

Cheers!

MF.

Hi
Im not sure but I think the adaptation channel reverts to 0 after you enter your value
My incorrect software version only appeared after I added the battery meter so think it is some sort of checksum for mmi
Did all you vcds tweeks stay after your visit to the dealer?

Andy

PS when I entered my new adaptation value the fault code cleared without me having to clear fault codes

I see! It looks like there is no need for me to do anything at this point, then. It's puzzling that the fault disappeared of its own accord, though.

I always reset all modules back to standard coding and adaptation values before the car goes in to the dealer. I reckon the tech servicing my car has enough pressure to do the job in a fixed time without getting distracted by non-standard module coding being flagged up. I only have the car for eight weeks, so I will probably leave the coding as standard now so I don't have to reset it all when the car goes.

Thanks for the useful info!

MF.
