ACC & City Braking - How Its Done -

[Robert]

tried to retrofit ACC together with online help (i dont know who the person is but he clearly has deep knowledge about this).

I would expert professional retrofitter with a deep knowledge to be able to answer your questions.

Apparantly all swap related things have been adressed

Good.

but what i've been told is I have a 7E0 709 379 P ABS pump which is likely not suitable to accept ACC.

All MK100 ABS units are ACC compatible.

Furthermore my ECU doesnt seem to be able to accept ACC code.

Typical problem for some coding interfaces.

My question is: Can my ECU be flashed to accept the ACC coding? (how can this be done, or can someone over here do this service)

No need for such a thing.

And do i need to swap my ABS pump for a N version or can my N version be flashed/coded to accept ACC?

No, you don't need to swap it.

No, you don't.

Thanks for your fast reply, but could you possibly help me out how to solve this matter? or am i asking too much? after all we are here to help each other.....

I would be happy to pay for any service if thats the problem.

Sure.

Please ask, this forum members help each other.

No need.

Can you post your complete VCDS AUTOSCAN before this "retrofit" and the current one?

 

[Marc R]

Thanks, I will try and fetch the data.

 

[Marc R]

This is the before and after scan... i hope this helps.

Engine code is CFCA

It must be very old school "retrofitter"

Who uses developer software version anymore?

ECU Coding before and after:

Your Instrument Cluster is not visible in the "after" scan, can you please redo?

I'll arrange that.

i hope its visible now.

Address 01: Engine (J623-CFCA) Labels:. 03L-906-022-CFC.clb

You have a EU5 ECU to get ACC working you need to patch the ECU Firmware.

First: you need to patch the CAN RX and TX Tables (i dont have it in Mind right now)
Second: you need to patch the CCS Stuff because the old EU5 did not support the new Button based CCS, i reversed this years ago, you can read it here: https://uk-polos.net/viewtopic.php?p=561683&sid=a00f80ffcd70d451747dcb716c5ab059#p561683
Third: You need to patch the Coding Whitlist to be able to code ACC in long coding

You need to read the ECU FW (2 MByte Binary), than i can patch it for you.
If you Engine is Stock than you can do a Virtual-Read, too.

Thank you very much, i'll need to look into this on how i can do this.

My van has been tuned so that could also be a problem.

if its needed can I DM you to adress the patching?

Shure you can DM me.
Easiest to get the File from the Tuner, and get him to flash it back via OBD.

I recently screen dumped the complete ECU info obtained by Carista for my T6 TSI DSG 204 Highline panel van (without ACC) and, as well as the ABS info that I noted in a post above, I’ve just noticed that it also listed the following ACC info:

Adaptive cruise control
Part #: 7N0907572C
Coding: 00005000FE0779 (hex)
Component: ACC Bosch PQx

What, if anything, can be gleaned from that?

Is it possible to install ACC in a Jetta 2.5 with an O7K engine? PQ35?

 

[dnoermann]

O7K engine

So i guess it is a Bosch MED17.5.6 ECU ?
I have no knowlage about that ECU, someone else ? @spacewalker probably ?

 

[pellizzoni]

Yes, MED17. 5.6

EU prefere Diesel

Look into Drive2.ru, they did some Skoda with petrol + ECU
