Retrofitting Cruise Control on A4 2014 model year (facelift)

[Franky_D]

Hi,

I've just received a retrofit kit from Kufatec. The hardware has been successfully installed. Now the question about coding.

Instructions from Kufatec say that two modules need to be coded:
- Module 16 (Steering), byte 2, bit 2 to get checked/activated. Done.
- Module 1 (Engine), byte 6, bit 0 to get checked/activated. It comes actually activated from the factory (original reading of byte 6 is 00000001).

Either the instructions are outdated or the engine module is too new (it's number 03L-906-018-JP), would need to find out which other bit/byte needs to be activated in the Engine module.

If only module 16 coded and no coding/changes in module 1, module 1 throughs an error and engine electronics lamp comes flashing on on the dash.

Just in case, the car is 2014 year model A4 2.0 tdi Avant .

While I'm waiting for advice from Kufatec and trying to find an official VCDS around to see if it provides clear instructions for which bit/byte needs activation, your ideas would be greatly appreciated!

Steering Wheel - 16 > Coding > Long Coding Helper > Select 'Cruise Control Installed'
Engine - 01 > Coding > Long Coding Helper > Select 'Cruise Control Installed'

iv not known engine 01 coded from factory when cruise not installed
above is what i use

The available version of VCDS (surely not original and not updated) does not recognize the Engine module and does not provide much suggestions (in fact none at all).... Therefore I am here...

I don't think the Engine 01 was coded. I rather believe that instructions from Kufatec are getting out of date and it's not bit 0 to be changed, but another one most probably ....

Thank you!

And here is the solution (thanks to a friend with original VCDS)!

For face-lift A4 model one needs to activate/check:
- Module 16 (Steering) -- byte 2, bit 2
- Module 1 (Engine) -- byte 5, bit 5

Hello Franky_D

I have a 2010 A4 allroad and my problem was the same. With byte 6 bit 1 the engine light flashing and cruise control don't work.
I try this new coding byte 5 bit 5 and now is working.
The only problem is doesn't display in odometer the speed that i set to cruise control. Do you have the same problem?

someone knows i can i solve this?

Thanks
