Hi 

I have a 2014 A6 Allroad 3.0 TDI 204hp with ACC and side assist. The side assist slave module (J770) has stopped working, with the effect that the ACC becomes unavailable as well. 
 

It seems that the OEM replacement part is hard to come by - 4G0907568 E - and my question is if anyone has any experience with a different part number working as a replacement. I can see that some sites are claiming that 4G0907568 M will fit my vehicle, but my dealership of course says that it won’t. 

I would greatly appreciate any tips or input, as I’m trying to get around having to buy a new way too expensive part from Audi. 

Привет.Хотелось бы узнать,как вы решили эту проблему,у меня такой же автомобиль и такая же проблема.

Спасибо

Hi, Allroadaudi

I see that it's been a while since you posted this question. I'm hoping that you have solved the problem with your car.

I'm having the exact same issue as you, and hunting down the module with the exact part number "4G0 907 568E" has turned out to be a real PIA.

Wondering if you eventually found the correct part or if you tried with something else?

Couple of used parts matching that description on EBay for £280 GBP plus postage (Europe), new, part is £670 for info.
